Awards and honours
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. He formally received the accolade at Buckingham Palace on 18 February 2009. Pratchett commented in the Ansible science fiction/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." On 31 December 2008, it was announced that Pratchett would be knighted (as a Knight Bachelor) in the Queen's 2009 New Year Honours. 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 2010, Pratchett created his own sword from deposits of iron he had found in a field near his home as he believed a knight should have a sword.
Ten honorary doctorates were conferred on Pratchett: from the 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 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.
Pratchett won the British Book Awards' "Fantasy and Science Fiction Author of the Year" category in 1994, the British Science Fiction Award in 1989 for his novel Pyramids, and a Locus Award for Best Fantasy Novel in 2008 for Making Money. He won the 2001 Carnegie Medal from the British librarians, which recognised 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. Four 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, 2007 and 2016. 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. In the same year, A Hat Full of Sky won a Mythopoeic Award. In 2008, Making Money was nominated for the Nebula Award for Best Novel. I Shall Wear Midnight won the 2010 Andre Norton Award, presented by the Science Fiction and Fantasy Writers of America (SFWA) as a part of the Nebula Award ceremony.
In 2016 SFWA named Pratchett the recipient of the Kate Wilhelm Solstice Award, given for "significant impact on the science fiction or fantasy landscape". He 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." In 2003 the 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.
An asteroid (127005 Pratchett) is named after Pratchett, as is the Australian spider Anelosimus pratchetti. In 2013 Pratchett was named Humanist of the Year by the British Humanist Association for his campaign to fund research into Alzheimers, his contribution to the right to die public debate and his Humanist values. 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 he 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.
In March 2017, Beaconsfield Town Council commissioned a commemorative plaque dedicated to Pratchett for Beaconsfield Library.
