Early career

Pratchett had his writing breakthrough in 1968 when he interviewed Peter Bander van Duren, co-director of a small publishing company, Colin Smythe Ltd. During the meeting, Pratchett mentioned he had written a manuscript, The Carpet People. Colin Smythe Ltd published the book in 1971, with illustrations by Pratchett. The book received strong, if few, reviews and was followed by the science fiction novels The Dark Side of the Sun (1976) and Strata (1981).

After various positions in journalism, in 1980 Pratchett became Press Officer for the Central Electricity Generating Board in an area which covered four nuclear power stations. He later joked that he had demonstrated "impeccable timing" by making this career change so soon after the Three Mile Island nuclear accident in Pennsylvania, US, and said he would "write a book about my experiences, if I thought anyone would believe it".

The first Discworld novel, The Colour of Magic, was published in hardback by Colin Smythe Ltd in 1983. The paperback edition was published by Corgi, an imprint of Transworld, in 1985. Pratchett's popularity increased when the BBC's Woman's Hour broadcast The Colour of Magic as a serial in six parts, and later Equal Rites. Subsequently, the hardback rights were taken by the publishing house Victor Gollancz Ltd, which remained Pratchett's publisher until 1997, and Colin Smythe became Pratchett's agent. Pratchett was the first fantasy author published by Gollancz.

Pratchett gave up working for the CEGB to make his living through writing in 1987, after finishing the fourth Discworld novel, Mort. His sales increased quickly and many of his books occupied top places on the best-seller list. According to The Times, Pratchett was the top-selling and highest earning UK author in 1996. Some of his books have been published by Doubleday, another Transworld imprint. In the US, Pratchett is published by HarperCollins.

According to the Bookseller's Pocket Yearbook (2005), in 2003 Pratchett's UK sales amounted to 3.4% of the fiction market by hardback sales and 3.8% by value, putting him in second place behind J. K. Rowling (6% and 5.6%, respectively), while in the paperback sales list Pratchett came 5th with 1.2% and 1.3% by value (behind James Patterson (1.9% and 1.7%), Alexander McCall Smith, John Grisham, and J. R. R. Tolkien). His sales in the UK alone are more than 2.5 million copies a year.

Later life

Pratchett married Lyn Purves in 1968, and they moved to Rowberrow, Somerset, in 1970. Their daughter Rhianna Pratchett, who is also a writer, was born there in 1976. In 1993, the family moved to Broad Chalke, a village west of Salisbury, Wiltshire. He listed his recreations as "writing, walking, computers, life". He described himself as a humanist and was a Distinguished Supporter of the British Humanist Association and an Honorary Associate of the National Secular Society. He was the patron of the Friends of High Wycombe Library. In 2013 he gave a talk at Beaconsfield Library which he had visited as a child and donated the income from the event to it. On a number of occasions he also visited his former school to speak to the students and look around.

Pratchett was well known for his penchant for wearing large, black fedora hats, as seen on the inside back covers of most of his books. His style has been described as "more that of urban cowboy than city gent."

Concern for the future of civilisation prompted him to install five kilowatts of photovoltaic cells (for solar energy) at his house. Having been interested in astronomy since childhood, he had an observatory built in his garden. An asteroid (127005 Pratchett) is named after him.

On 31 December 2008, it was announced that Pratchett was to be knighted (as a Knight Bachelor) in the Queen's 2009 New Year Honours. He formally received the accolade at Buckingham Palace on 18 February 2009. Afterwards he said, "You can't ask a fantasy writer not to want a knighthood. You know, for two pins I'd get myself a horse and a sword." In late 2009, he did make himself a sword, with the help of his friends. He told a Times Higher Education interviewer that “At the end of last year I made my own sword. I dug out the iron ore from a field about 10 miles away - I was helped by interested friends. We lugged 80 kilos of iron ore, used clay from the garden and straw to make a kiln, and lit the kiln with wildfire by making it with a bow.' Colin Smythe, his long-term friend and agent, donated some pieces of meteoric iron - ‘thunderbolt iron’ has a special place in magic and we put that in the smelt, and I remember when we sawed the iron apart it looked like silver. Everything about it I touched, handled and so forth ... And everything was as it should have been, it seemed to me.”

Alzheimer's disease

In August 2007, Pratchett was misdiagnosed as having had a minor stroke in 2004 or 2005, which doctors believed had damaged the right side of his brain. While his motor skills were affected, the observed damage had not impaired his ability to write. On 11 December 2007, Pratchett posted online that he had been newly diagnosed with early-onset Alzheimer's disease, which had been responsible for the "stroke". He had a rare form of the disease, posterior cortical atrophy (PCA), in which areas at the back of the brain begin to shrink and shrivel.

Describing the diagnosis as an "embuggerance" in a radio interview, Pratchett appealed to people to "keep things cheerful" and proclaimed that "we are taking it fairly philosophically down here and possibly with a mild optimism." He stated he felt he had time for "at least a few more books yet", and added that while he understood the impulse to ask "is there anything I can do?", in this case he would only entertain such offers from "very high-end experts in brain chemistry." Discussing his diagnosis at the Bath Literature Festival in early 2008, Pratchett revealed that by then he found it too difficult to write dedications when signing books. In his later years Pratchett wrote by dictating to his assistant, Rob Wilkins, or by using speech recognition software.

In March 2008, Pratchett announced he would donate US$1,000,000 (about £494,000) to the Alzheimer's Research Trust, and that he was shocked "to find out that funding for Alzheimer's research is just 3% of that to find cancer cures." He said: "I am, along with many others, scrabbling to stay ahead long enough to be there when the Cure comes along."

In April 2008, Pratchett worked with the BBC to make a two-part documentary series about his illness, Terry Pratchett: Living With Alzheimer's. The first part was broadcast on BBC Two on 4 February 2009, drawing 2.6m viewers and a 10.4% audience share. The second, broadcast on 11 February 2009, drew 1.72m viewers and a 6.8% audience share. The documentary won a BAFTA award in the Factual Series category. Pratchett also made an appearance on The One Show on 15 May 2008, talking about his condition. He was the subject and interviewee of the edition of 20 May 2008 of On the Ropes (Radio 4), discussing Alzheimer's and how it had affected his life.

On 8 June 2008, news reports indicated that Pratchett had an experience which he described as: "It is just possible that once you have got past all the gods that we have created with big beards and many human traits, just beyond all that, on the other side of physics, there just may be the ordered structure from which everything flows" and "I don't actually believe in anyone who could have put that in my head". He went into further detail on Front Row, in which he was asked if this was a shift in his beliefs: "A shift in me in the sense I heard my father talk to me when I was in the garden one day. But I'm absolutely certain that what I heard was my memories of my father. An engram, or something in my head...This is not about God, but somewhere around there is where gods come from."

On 26 November 2008, Pratchett met the Prime Minister Gordon Brown and asked for an increase in dementia research funding. From August 2008, Pratchett tested a prototype device to address his condition. Despite some apparent improvements, the ability of the device to alter the course of the illness has been met with scepticism from Alzheimer's researchers.

In an article published mid-2009, Pratchett stated that he wished to die by assisted suicide (although he disliked that term) before his disease progressed to a critical point. He later said he felt "it should be possible for someone stricken with a serious and ultimately fatal illness to choose to die peacefully with medical help, rather than suffer." Pratchett was selected to give the 2010 BBC Richard Dimbleby Lecture, entitled Shaking Hands With Death, broadcast on 1 February 2010. Pratchett introduced his lecture on the topic of assisted death, but the main text was read by his friend Tony Robinson because Pratchett's condition made it difficult for him to read. In June 2011 Pratchett presented a one-off BBC television documentary, Terry Pratchett: Choosing to Die, about assisted suicide. It won the Best Documentary award at the Scottish BAFTAs in November 2011.

In September 2012 Pratchett stated: "I have to tell you that I thought I’d be a lot worse than this by now, and so did my specialist." In the same interview, he stated that the cognitive part of his mind was "untouched" and his symptoms were physical (normal for PCA). However, in July 2014 he cancelled his appearance at the biennial International Discworld Convention, saying: "the Embuggerance is finally catching up with me, along with other age-related ailments".

Death

Pratchett died at his home on the morning of 12 March 2015 from his Alzheimer's, according to his publisher. The Telegraph reported an unidentified source as saying that despite his previous discussion of assisted suicide, his death had been natural. After Pratchett's death, his assistant, Rob Wilkins, wrote from the official Terry Pratchett Twitter account:

AT LAST, SIR TERRY, WE MUST WALK TOGETHER.

Terry took Death's arm and followed him through the doors and on to the black desert under the endless night.

The End.

The use of small capitals is a reference to how the character of Death speaks in Pratchett's works.

Many public figures paid tribute following Pratchett's death, including British Prime Minister David Cameron and the comedian Ricky Gervais, and authors including Nick Harkaway, Ursula Le Guin, Terry Brooks, Margaret Atwood, George R. R. Martin, and Neil Gaiman. Pratchett was memorialised in a graffito in East London, and the video game company Frontier Developments added a space station to Elite: Dangerous named "Pratchett's Disc". Developers of Dota 2, Valve Corporation, added an item to their game called "Octarine Core". In reference to Pratchett's Novel "The Colour of Magic". Users of the social news site Reddit organised a tribute by which an HTTP header, "X-Clacks-Overhead: GNU Terry Pratchett", is added to a site's responses, a reference to the Discworld novel Going Postal.

Pratchett's humanist funeral service was held on 25 March 2015.

Interests

Computers and the Internet

Pratchett started to use computers for writing as soon as they were available to him. His first computer was a Sinclair ZX81; the first computer he used properly for writing was an Amstrad CPC 464, later replaced by a PC. Pratchett was one of the first authors routinely to use the Internet to communicate with fans, and was a contributor to the Usenet newsgroup alt.fan.pratchett from 1992. However, he did not consider the Internet a hobby, just another "thing to use". He had many computers in his house, with a bank of six monitors rigged up to ease writing. When he travelled, he always took a portable computer with him to write.

His experiments with computer upgrades are reflected in Hex.

Pratchett was also an avid video game player, and collaborated in the creation of a number of game adaptations of his books. He favoured games that are "intelligent and have some depth", citing Half-Life 2 and fan missions from Thief as examples. Additionally, he played Oblivion, which he described as "wonderful", and used many of its non-combat-oriented, fan-made mods. He is also said to have enjoyed playing the first Tomb Raider game.

Natural history

Pratchett had a fascination with natural history that he referred to many times, and he owned a greenhouse full of carnivorous plants.

In 1995, a fossil sea-turtle from the Eocene epoch of New Zealand was named in honour of him Psephophorus terrypratchetti by the palaeontologist Richard Köhler.

In 2016, Pratchett fans petitioned the International Union of Pure and Applied Chemistry to name chemical element 117, currently referred to as Ununseptium, as Octarine, with the proposed symbol Oc (pronounced 'ook').

Orangutans

Pratchett was a trustee for the Orangutan Foundation UK but was pessimistic about the animal's future. His activities included visiting Borneo with a Channel 4 film crew to make an episode of "Jungle Quest" in 1995, seeing orangutans in their natural habitat. Following Pratchett's lead, fan events such as the Discworld Conventions have adopted the Orangutan Foundation as their nominated charity, which has been acknowledged by the foundation. One of Pratchett's most popular fictional characters, the Librarian of the Unseen University's Library, is a wizard who was transformed into an orangutan in a magical accident and decides to remain in that condition as it is so convenient for his work.

Amateur astronomy

Pratchett had an observatory in his back garden and was a keen astronomer from childhood. He made an appearance on the BBC programme The Sky at Night.

Terry Pratchett First Novel Award

Pratchett sponsored a biennial award for unpublished science fiction novelists, the Terry Pratchett First Novel Award. The prize is a publishing contract with his publishers Transworld. In 2011 the award was won jointly by David Logan for Half Sick of Shadows and Michael Logan for Apocalypse Cow. In 2013 the award was won by Alexander Maskill for The Hive.

Sir Terry Pratchett Memorial Scholarship

In 2015, the estate of the late Sir Terry Pratchett announced an in-perpetuity endowment to the University of South Australia. The Sir Terry Pratchett Memorial Scholarship supports a Masters scholarship at the University’s Hawke Research Institute.

Writing career

Awards

Pratchett received a knighthood for "services to literature" in the 2009 UK New Year Honours list. He was previously appointed Officer of the Order of the British Empire, also for "services to literature", in 1998. Following this, Pratchett commented in the Ansible SF/fan newsletter, "I suspect the 'services to literature' consisted of refraining from trying to write any," but added, "Still, I cannot help feeling mightily chuffed about it."

Pratchett was the British Book Awards' 'Fantasy and Science Fiction Author of the Year' for 1994.

Pratchett won the British Science Fiction Award in 1989 for his novel, Pyramids, and a Locus Award for Best Fantasy Novel in 2008 for Making Money.

Pratchett was awarded ten honorary doctorates: University of Warwick in 1999, the University of Portsmouth in 2001, the University of Bath in 2003, the University of Bristol in 2004, Buckinghamshire New University in 2008, the University of Dublin in 2008, Bradford University in 2009, University of Winchester in 2009, The Open University in 2013 for his contribution to Public Service and his last, from the University of South Australia, in May 2014.

Pratchett won the 2001 Carnegie Medal from the British librarians, recognising The Amazing Maurice and His Educated Rodents as the year's best children's book published in the UK.

Night Watch won the 2003 Prometheus Award for best libertarian novel.

In 2003, BBC conducted The Big Read to identify the "Nation's Best-loved Novel" and finally published a ranked list of the "Top 200". Pratchett's highest-ranking novel was Mort, number 65, but he and Charles Dickens were the only authors with five in the Top 100 (four of his were from the Discworld series). He also led all authors with fifteen novels in the Top 200.

Three of the five Discworld novels that centre on the "trainee witch" Tiffany Aching won the annual Locus Award for Best Young Adult Book in 2004, 2005 and 2007.

In 2005, Going Postal was shortlisted for the Hugo Award for Best Novel; however, Pratchett recused himself, stating that stress over the award would mar his enjoyment of Worldcon.

Pratchett received the NESFA Skylark Award in 2009 and the World Fantasy Award for Life Achievement in 2010. In 2011 he won Margaret A. Edwards Award from the American Library Association, a lifetime honour for "significant and lasting contribution to young adult literature". The librarians cited nine Discworld novels published from 1983 to 2004 and observed that "Pratchett’s tales of Discworld have won over generations of teen readers with intelligence, heart, and undeniable wit. Comic adventures that fondly mock the fantasy genre, the Discworld novels expose the hypocrisies of contemporary society in an intricate, ever-expanding universe. With satisfyingly multilayered plots, Pratchett's humor honors the intelligence of the reader. Teens eagerly lose themselves in a universe with no maps."

He was made an adjunct Professor in the School of English at Trinity College Dublin in 2010, with a role in postgraduate education in creative writing and popular literature.

I Shall Wear Midnight won the 2010 Andre Norton Award for Young Adult Science Fiction and Fantasy presented by the Science Fiction and Fantasy Writers of America (SFWA) as a part of the Nebula Award ceremony. In 2016, SFWA announced that Sir Terry would be the recipient of the Kate Wilhelm Solstice Award, presented at the 2016 SFWA Nebula Conference.

Fanbase

Pratchett's Discworld novels have led to dedicated conventions, the first in Manchester in 1996, then worldwide, often with the author as guest of honour. Publication of a new novel was sometimes accompanied by an international book signing tour; queues were known to stretch outside the bookshop as the author continued to sign books well after the intended finishing time. His fans were not restricted by age or gender, and he received a large amount of fan mail from them. Pratchett enjoyed meeting fans and hearing what they think about his books, saying that since he was well paid for his novels, his fans were "everything" to him.

Writing

Pratchett said that to write, you must read extensively, both inside and outside your chosen genre and to the point of "overflow". He advised that writing is hard work, and that writers must "make grammar, punctuation and spelling a part of your life." However, Pratchett enjoyed writing, regarding its monetary rewards as "an unavoidable consequence", rather than the reason for writing.

Fantasy genre

Although during his early career he wrote for the sci-fi and horror genres, Pratchett later focused almost entirely on fantasy, and said: "It is easier to bend the universe around the story." In the acceptance speech for his Carnegie Medal he said: "Fantasy isn't just about wizards and silly wands. It's about seeing the world from new directions", pointing to J. K. Rowling's Harry Potter novels and J. R. R. Tolkien's The Lord of the Rings. In the same speech, he acknowledged benefits of these works for the genre.

Pratchett believed he owed "a debt to the science fiction/fantasy genre which he grew up out of" and disliked the term "magical realism" which, he said, is "like a polite way of saying you write fantasy and is more acceptable to certain people ... who, on the whole, do not care that much." He expressed annoyance that fantasy is "unregarded as a literary form", arguing that it "is the oldest form of fiction"; he described himself as "infuriated" when novels containing science fiction or fantasy ideas were not regarded as part of those genres. He debated this issue with novelist A. S. Byatt and critic Terry Eagleton, arguing that fantasy is fundamental to the way we understand the world and therefore an integral aspect of all fiction.

On 31 July 2005, Pratchett criticised media coverage of Harry Potter author J. K. Rowling, commenting that certain members of the media seemed to think that "the continued elevation of J. K. Rowling can be achieved only at the expense of other writers". Pratchett later denied claims that this was a swipe at Rowling, and said that he was not making claims of plagiarism, but was pointing out the "shared heritage" of the fantasy genre. Pratchett also posted on the Harry Potter newsgroup about a media-covered exchange of views with her.

Style and themes

Pratchett is known for a distinctive writing style that included a number of characteristic hallmarks. One example is his use of footnotes, which usually involve a comic departure from the narrative or a commentary on the narrative, and occasionally have footnotes of their own.

Pratchett's earliest Discworld novels were written largely to parody classic sword-and-sorcery fiction (and occasionally science-fiction); as the series progressed, Pratchett dispensed with parody almost entirely, and the Discworld series evolved into straightforward (though still comedic) satire.

Pratchett had a tendency to avoid using chapters, arguing in a Book Sense interview that "life does not happen in regular chapters, nor do movies, and Homer did not write in chapters", adding "I'm blessed if I know what function they serve in books for adults." However, there have been exceptions; Going Postal and Making Money and several of his books for younger readers are divided into chapters. Pratchett offered explanations for his sporadic use of chapters; in the young adult titles, he said that he must use chapters because ' editor screams until does', but otherwise felt that they were an unnecessary 'stopping point' that got in the way of the narrative.

Characters, place names, and titles in Pratchett's books often contain puns, allusions and culture references. Some characters are parodies of well-known characters: for example, Pratchett's character Cohen the Barbarian, also called Ghengiz Cohen, is a parody of Conan the Barbarian and Genghis Khan, and his character Leonard of Quirm is a parody of Leonardo da Vinci.

Another hallmark of his writing was the use of capitalised dialogue without quotation marks, used to indicate the character of Death communicating telepathically into a character's mind. Other characters or types of characters were given similarly distinctive ways of speaking, such as the auditors of reality never having quotation marks, Ankh-Morpork grocers never using punctuation correctly, and golems capitalising each word in everything they say. Pratchett also made up a new colour, octarine, a 'fluorescent greenish-yellow-purple', which is the eighth colour in the Discworld spectrum—the colour of magic. Indeed, the number eight itself is regarded in the Discworld as being a magical number; for example, the eighth son of an eighth son will be a wizard, and his eighth son will be a "sourcerer" (which is one reason why wizards are not allowed to have children).

Discworld novels often included a modern innovation and its introduction to the world's medieval setting, such as a public police force (Guards! Guards!), guns (Men at Arms), submarines (Jingo), cinema (Moving Pictures), investigative journalism (The Truth), the postage stamp (Going Postal), modern banking (Making Money), and the steam engine (Raising Steam). The "clacks", the tower-to-tower semaphore system that sprang up in later novels, is a mechanical optical telegraph (used in Napoleon's Era successfully) before wired electric telegraph chains, with all the change and turmoil that such an advancement implies. The resulting social upheaval driven by these changes serves as the setting for the main story.

Influences

Pratchett made no secret of outside influences on his work: they were a major source of his humour. He imported numerous characters from classic literature, popular culture and ancient history, always adding an unexpected twist. Pratchett was a crime novel fan, which was reflected in frequent appearances of the Ankh-Morpork City Watch in the Discworld series. Pratchett was an only child, and his characters are often without siblings. Pratchett explained, "In fiction, only-children are the interesting ones".

Pratchett's earliest inspirations were The Wind in the Willows by Kenneth Grahame, and the works of Isaac Asimov and Arthur C. Clarke. His literary influences have been P.G. Wodehouse, Tom Sharpe, Jerome K. Jerome, Roy Lewis, Alan Coren, G. K. Chesterton, and Mark Twain.

Publishing history

While Pratchett's UK publishing history remained quite stable, his relationships with international publishers were turbulent (especially in America). He changed German publishers after an advertisement for Maggi soup appeared in the middle of the German-language version of Pyramids.

Works

The Discworld series

Main article: Discworld

Pratchett began writing the Discworld series in 1983 to "have fun with some of the cliches" and it is a humorous and often satirical sequence of stories set in the colourful fantasy Discworld universe. The series contains various story arcs (or sub-series), and a number of free-standing stories. All are set in an abundance of locations in the same detailed and unified world, such as the Unseen University and 'The Drum/Broken Drum/Mended Drum' public house in the twin city Ankh-Morpork, or places in the various continents, regions and countries on the Disc. Characters and locations reappear throughout the series, variously taking major and minor roles.

The Discworld itself is described as a large disc resting on the backs of four giant elephants, all supported by the giant turtle Great A'Tuin as it swims its way through space. The books are essentially in chronological order, and advancements can be seen in the development of the Discworld civilisations, such as the creation of paper money in Ankh-Morpork.

Many of the novels in Pratchett's Discworld series parody real-world subjects such as film making, newspaper publishing, rock and roll music, religion, philosophy, Ancient Greece, Egyptian history, the Gulf War, Australia, university politics, trade unions, and the financial world. Pratchett also included further parody as a feature within the stories, including such subjects as Ingmar Bergman films, numerous fiction, science fiction, and fantasy characters, and various bureaucratic and ruling systems.

Other Discworld books

Pratchett wrote or collaborated on a number of Discworld books that are not novels in themselves but serve to accompany the series.

The Discworld Companion, written with Stephen Briggs, is an encyclopaedic guide to Discworld. The third edition was renamed The New Discworld Companion, and was published in 2003. The fourth and most recent edition of the companion, Turtle Recall was published on 18 October 2012. Briggs also collaborated with Pratchett on a series of fictional Discworld "mapps". The first, The Discworld Mapp (1995), illustrated by Stephen Player, comprises a large, comprehensive map of the Discworld itself with a small booklet that contains short biographies of the Disc's prominent explorers and their discoveries. Three further "mapps", have been released, focusing on particular regions of the Disc: Ankh-Morpork, Lancre, and Death's Domain.

Between 1997 and 2015, ten Discworld Diaries were published as collaborations with Briggs or the Discword Emporium. Pratchett and Tina Hannan collaborated on Nanny Ogg's Cookbook (1999). The design of this cookbook, illustrated by Paul Kidby, was based on the traditional Mrs Beeton's Book of Household Management, but with humorous recipes. Pratchett and Bernard Pearson collaborated on The Discworld Almanak, for the Year of the Prawn, with illustration by Paul Kidby, Pearson and Sheila Watkins.

Collections of Discworld-related art have also been released in book form. The Pratchett Portfolio (1996) and The Art of Discworld (2004) are collections of paintings of major Discworld characters by Paul Kidby, with details added by Pratchett on the character's origins.

In 2005, Pratchett's first book for very young children was Where's My Cow? Illustrated by Melvyn Grant, this is a realisation of the short story Sam Vimes reads to his child in Thud!.

The Unseen University Cut Out Book was published in 2006 developed with Alan Bately and Bernard Pearson. The book contains cut-out templates of seven of the major buildings in the Unseen University.

Following on from the release of Sky's adaptation of Hogfather, Terry Pratchett's Hogfather, The Illustrated Screenplay was released in 2006. It was written by Vadim Jean and "mucked about with by Terry Pratchett". It contains the final shooting script, pictures from the film and additional illustrations by Stephen Player. It was published by Gollancz.

Pratchett and the Discworld Emporium published The Compleat Ankh-Morpork City Guide in 2012 which combined a trade directory, gazetteer, laws and ordinances together with a fully revised city map with artwork by Bernard Pearson, Ian Mitchell and Peter Dennis.

A number of publications have been released on the back of Pratchett's novels with the participation of the Discworld Emporium:

• The World of Poo; a book by Miss Felicity Beedle who features in Snuff (2012)
• Mrs Bradshaw's Handbook: an illustrated guide to Discworld railway (Raising Steam, 2014)

Pratchett resisted mapping the Discworld for quite some time, noting that a firmly designed map restricts narrative possibility (i.e., with a map, fans would complain if he placed a building on the wrong street, but without one, he could adjust the geography to fit the story).

The Science of Discworld

Pratchett wrote four Science of Discworld books in collaboration with Professor of mathematics Ian Stewart and reproductive biologist Jack Cohen, both of the University of Warwick: The Science of Discworld (1999), The Science of Discworld II: The Globe (2002), The Science of Discworld III: Darwin's Watch (2005), and The Science of Discworld IV: Judgement Day (2013).

All four books have chapters that alternate between fiction and non-fiction: the fictional chapters are set within the Discworld universe, where characters observe, and experiment on, a universe with the same physics as ours. The non-fiction chapters (written by Stewart and Cohen) explain the science behind the fictional events.

In 1999, Pratchett appointed both Cohen and Stewart as "Honorary Wizards of the Unseen University" at the same ceremony at which the University of Warwick awarded him an honorary degree.

Folklore of Discworld

Pratchett collaborated with the folklorist Dr Jacqueline Simpson on The Folklore of Discworld (2008), a study of the relationship between many of the persons, places and events described in the Discworld books and their counterparts in myths, legends, fairy tales and folk customs on Earth.

Other novels and writing

Pratchett's first two adult novels, The Dark Side of the Sun (1976) and Strata (1981), were both science-fiction, the latter taking place partly on a disc-shaped world. Subsequent to these, Pratchett mostly concentrated on his Discworld series and novels for children, with two exceptions: Good Omens (1990), a collaboration with Neil Gaiman (which was nominated for both Locus and World Fantasy Awards in 1991), a humorous story about the Apocalypse set on Earth, and Nation (2008), a book for young adults.

After writing Good Omens, Pratchett began to work with Larry Niven on a book that would become Rainbow Mars; Niven eventually completed the book on his own, but states in the afterword that a number of Pratchett's ideas remained in the finished version.

Pratchett also collaborated with British science fiction author Stephen Baxter on a parallel earth series. The first novel, entitled The Long Earth was released on 21 June 2012. A second novel, The Long War, was released on 18 June 2013. The Long Mars was published in 2014. The fourth book in the series, The Long Utopia, was published in June 2015.

In 2012, the first volume of Pratchett's collected short fiction was published under the title A Blink of the Screen. In 2014, a similar collection was published of Pratchett's non-fiction, entitled A Slip of the Keyboard.

Juvenile literature

Pratchett's first children's novel was also his first published novel: The Carpet People in 1971, which Pratchett substantially rewrote and re-released in 1992. The next, Truckers (1988), was the first in The Nome Trilogy of novels for young readers, about small gnome-like creatures called "Nomes", and the trilogy continued in Diggers (1990) and Wings (1990). Subsequently, Pratchett wrote the Johnny Maxwell trilogy, about the adventures of a boy called Johnny Maxwell and his friends, comprising Only You Can Save Mankind (1992), Johnny and the Dead (1993) and Johnny and the Bomb (1996). Nation (2008) marked his return to the non-Discworld children's novel, and this was followed in 2012 by Dodger, a children's novel set in Victorian London. On 21 November 2013 Doubleday Children's released Pratchett's Jack Dodger's Guide to London.

In September 2014 an anthology of children's stories, Dragons at Crumbling Castle, written by Pratchett, and illustrated by Mark Beech, was published.

Unfinished texts

According to Pratchett's assistant Rob Wilkins, Pratchett left "an awful lot" of unfinished writing, "10 titles I know of and fragments from many other bits and pieces." In the past, Pratchett himself mentioned at least two texts, Scouting for Trolls, and a Discworld novel centering on a new character. The notes left behind outline ideas about “how the old folk of the Twilight Canyons solve the mystery of a missing treasure and defeat the rise of a Dark Lord despite their failing memories”, “the secret of the crystal cave and the carnivorous plants in the Dark Incontinent”, about Constable Feeney of the Watch, first introduced in Snuff, involving how he “solves a whodunnit among the congenitally decent and honest goblins”, and on a second book about Amazing Maurice from The Amazing Maurice and His Educated Rodents.

Pratchett's daughter is the current custodian of the Discworld franchise, and has stated on several occasions that she has no plans to publish any of her father's unfinished work, or to continue the Discworld on her own.

Adaptations

Comic books and graphic novels

Four graphic novels of Pratchett's work have been released. The first two, originally published in the US, were adaptations of The Colour of Magic and The Light Fantastic and illustrated by Steven Ross (with Joe Bennett on the latter). The second two, published in the UK, were adaptations of Mort (subtitled A Discworld Big Comic) and Guards! Guards!, both illustrated by Graham Higgins and adapted by Stephen Briggs. The graphic novels of The Colour of Magic and The Light Fantastic were republished by Doubleday on 2 June 2008. An adaption of Small Gods is planned for release on 28 June 2016.

Feature films

Pratchett held back from Discworld feature films; though the rights to a number of his books have been sold, no films have yet been made.

• Director Terry Gilliam announced in an 1999 interview with Empire magazine that he planned to adapt Good Omens, but as of 2007 this still needed funding.
• In 2001, DreamWorks commissioned a Truckers adaptation by Andrew Adamson and Joe Stillman but Pratchett believed that it will not be made until after "Shrek 17".
• In 2006, it was reported that The Wee Free Men was set to be directed by Sam Raimi, but in 2009 Pratchett said that he had "got back" after reading the proposed screenplay.
• In 2008, Danny Boyle revealed that he hoped to direct a Truckers adaptation by Frank Cottrell Boyce.

Internet games

Main article: Discworld MUD

• The world of Discworld is featured in a fan-created online MUD (multi-user dungeon), which allows players to play humans in various guilds within the universe that Pratchett created.

Music

• From The Discworld (1994) is a collection of 14 songs by Dave Greenslade inspired by the Discworld novels, with the author contributing to the production of the record. The album features songs and instrumentals about the books as well as some that appear in the novels, such as "A Wizard's Staff has a Knob on the End". The video of Soul Music used parts of the complete songs that were actually written and performed by Keith Hopwood and Phil Bush; the complete songs were released on an audio CD.
• Steeleye Span co-operated with Terry Pratchett to write and produce the album Wintersmith (October 2013), based on the novels featuring the Wee Free Men.

Radio

Pratchett had a number of radio adaptations on BBC Radio 4: The Colour of Magic, Equal Rites (on Woman's Hour), Only You Can Save Mankind, Guards! Guards!, Wyrd Sisters, Mort, and Small Gods have all been dramatised as serials, as was Night Watch in early 2008, and The Amazing Maurice and his Educated Rodents as a 90-minute play.

The 4-part BBC Radio 4 adaptation of Eric by Robin Brooks again started on 6 March 2013.

Guards! Guards! was adapted as a one-hour audio drama by the Atlanta Radio Theatre Company and performed live at Dragon*Con in 2001.

In 2014, a six-part adaption of Good Omens aired on BBC Radio 4, and featured cameos by both Terry Pratchett and Neil Gaiman.

Television

Truckers was adapted as a stop motion animation series for Thames Television by Cosgrove Hall Films in 1992. Johnny and the Dead was made into a TV serial for Children's ITV on ITV, in 1995. Wyrd Sisters and Soul Music were adapted as animated cartoon series by Cosgrove Hall for Channel 4 in 1996; illustrated screenplays of these were published in 1998 and 1997 respectively. In January 2006, BBC One aired a three-part adaptation of Johnny and the Bomb.

A two-part, feature-length version of Hogfather starring David Jason and the voice of Ian Richardson was first aired on Sky One in the United Kingdom in December 2006, and on ION Television in the US in 2007. Pratchett was opposed to live action films about Discworld before because of his negative experience with Hollywood film makers. He changed his opinion when he saw that the director Vadim Jean and producer Rod Brown were very enthusiastic and cooperative. A two-part, feature-length adaptation of The Colour of Magic and its sequel The Light Fantastic aired during Easter 2008 on Sky One. A third adaptation, Going Postal was aired at the end of May 2010. The Sky adaptations are notable also for the author's presence in cameo roles. He is also credited as having "mucked about" with these adaptations.

In 2012, Pratchett founded a television production company of his own, Narrativia, which is to hold the rights to his works, and which is in development of a television series, The Watch, based on the Ankh-Morpork City Watch.

In 2016, Neil Gaiman stated that Terry had given him his blessing to go forward with an adaptation of Good Omens if he so wished. It is currently formatted as a six-part series.

Theatre

Twenty one of Pratchett's novels have been adapted as plays by Stephen Briggs and published in book form. They were first produced by the Studio Theatre Club in Abingdon, Oxfordshire. They include adaptations of The Truth, Maskerade, Mort, Wyrd Sisters and Guards! Guards! Stage adaptations of Discworld novels have been performed on every continent in the world, including Antarctica.

In addition, Lords & Ladies has been adapted for the stage by Irana Brown, and Pyramids was adapted for the stage by Suzi Holyoake in 1999 and had a week-long theatre run in the UK. In 2002, an adaptation of Truckers was produced as a co-production between Harrogate Theatre, the Belgrade Theatre Coventry and Theatre Royal, Bury St. Edmunds. It was adapted by Bob Eaton, and directed by Rob Swain. The play toured to many venues in the UK between 15 March and 29 June 2002.

A version of Eric adapted for the stage by Scott Harrison and Lee Harris was produced and performed by The Dreaming Theatre Company in June/July 2003 inside Clifford's Tower, the 700-year-old castle keep in York. It was revived in 2004 in a tour of England along with Robert Rankin's The Antipope.

In 2004, a musical adaptation of Only You Can Save Mankind was premiered at the Edinburgh Festival, with music by Leighton James House and book and lyrics by Shaun McKenna.

In January 2009, the National Theatre announced that their annual winter family production in 2009 would be a theatrical adaptation of Pratchett's novel Nation. The novel was adapted by playwright Mark Ravenhill and directed by Melly Still. The production premiered at the Olivier Theatre on 24 November, and ran until 28 March 2010. It was broadcast to cinemas around the world on 30 January 2010.

Pratchett worked with Youth Music Theatre UK several times over the last few years to bring adaptations of both Mort and Soul Music to the stage. In August 2014, a brand new adaptation of Soul Music will be performed at the Rose Theatre, Kingston.

Role-playing games

GURPS Discworld (Steve Jackson Games, 1998) and GURPS Discworld Also (Steve Jackson Games, 2001) are role-playing source books which were written by Terry Pratchett and Phil Masters, which also offer insights into the workings of the Discworld. The first of these two books was re-released in September 2002 under the name of The Discworld Roleplaying Game, with art by Paul Kidby.

Video games

The Discworld universe has also been used as a basis for a number of video games on a range of formats, such as the Sega Saturn, the Sony PlayStation, the Philips CD-i, and the 3DO, as well as DOS and Windows-based PCs. The following are the more notable games:

• The Colour of Magic, the first game based on the series, and so far the only one directly adapted from a Discworld novel. It was released in 1986 for the Sinclair ZX Spectrum and Commodore 64.
• Discworld, an animated "point-and-click" adventure game made by Teeny Weeny Games and Perfect 10 Productions in 1995.
• Discworld II: Missing Presumed...!?, a sequel to Discworld developed by Perfect Entertainment in 1996. It was subtitled "Mortality Bytes!" in North America.
• Discworld Noir is the first 3D game based on the Discworld series, and is both a parody of the film noir genre and an example of it. The game was created by Perfect Entertainment and published by GT Interactive for both the PC and PlayStation in 1999. It was released only in Europe and Australia.

Board games

So far there have been five games published relating to Discworld

• Thud, 2002, by Trevor Truran, publisher The Cunning Artificer. It resembles ancient Norse games such as Hnefatafl, and involves two unequal sides, Trolls and Dwarves with different moves and 'capture' abilities.
• Guards Guards, 2011, by Backspindle Games (Designers: Leonard Boyd & David Brashaw), Published in conjunction with Z-Man Games. This is a 'quest' game where players have to manoeuvre their piece around the board collecting stolen spells to return to the Unseen University, while dealing with various Discworld characters.
• Ankh-Morpork, 2011, by Martin Wallace, published by Treefrog Games. This is a game where each player has a secret victory condition, usually relating to owning buildings in, or controlling, various areas of the city of Ankh-Morpork. During the game, players play cards from their hand to place control elements in the city, remove other players' pieces, or otherwise manipulate the ownership of areas.
• The Witches, 2013, by Martin Wallace, published by Treefrog Games. This is a game aimed at younger or more family oriented players. They must move around the town of Lancre and its surrounds, dealing with 'problems' ranging from a sick pig, to an invasion by vampires. Each player has a one-use special power. It is a semi-cooperative game, in that all players can lose if the game wins, but if they resolve all the problems, then one of them will win.
• Clacks, 2014, by Backspindle Games (Designers: Leonard Boyd & David Brashaw), Published in conjunction with Z-Man Games. In this game players compete to send their 'message' on a clacks board while disrupting their opponents' messages. It resembles the game Amoeba, with its constantly changing board.
