Discworld Diary

The Discworld Diaries are a series of themed diaries based on the Discworld novels by Terry Pratchett. Each one (except the 2008 diary) is based on an Ankh-Morpork institution, and has an opening section containing information about that institution written by Pratchett and Stephen Briggs.

The diaries feature a great deal of background information, far more than could reasonably be put into the novels. However, some of this occasionally finds its way into the series proper - the concept of female assassins, the introduction of Black Widow House, and the characters of Miss Alice Band and Mme les Deux-Épées were notable ideas that first appeared in the Assassins' Guild Yearbook, and later in the Discworld short story "Minutes of the Meeting to Form the Proposed Ankh-Morpork Federation of Scouts" in A Blink of the Screen, to then becoming characters and a playable Assassins' Guild House in Discworld MUD.

The early diaries are illustrated by Paul Kidby.

Those for 2015 and 2016 were by Pratchett aided and abetted by the Discworld Emporium, with additional illustrations by Peter Dennis

The diaries are:
 * Discworld's Unseen University Diary 1998 (1997); the cover art features the character Death, possibly the character who appeared in the greatest number of Discworld novels.
 * Discworld's Ankh-Morpork City Watch Diary 1999 (1998); the cover art features the character Commander Samuel Vimes of the Watch, His Grace the Duke of Ankh, in his beloved street uniform, in other words, battered Watchman armor.

There were no diaries published for the years 2004-2006, and 2009-2015; The Discworld Almanak by Pratchett and Bernard Pearson was published in 2004.

Due to their limited edition nature, Discworld Diaries become increasingly valuable as they grow older. As of 2016, the 1998 Discworld's Unseen University Diary was available for around £90.
