A standard Hogwarts textbook classifying the magical creatures of the world, and one of the few fictional books you can order tonight and have on your desk tomorrow.
A cookery book by Nanny Ogg, published anonymously as "A Lady", in which almost every recipe turns out to be about something other than food.
The most famous book that does not exist. A grimoire of pre-human history and summoning rites, surviving in a handful of guarded copies, quoted just often enough to convince generations of readers it was real.
A history of the game from the marshes of Queerditch to the modern professional leagues, borrowed from the Hogwarts library and never quite returned on time.
A book of wizarding fairy tales left to Hermione Granger in Dumbledore's will. One of the five stories in it turns out to be the plot of the novel.
A picture book about a lost cow, read to a baby by the most dangerous man in Ankh-Morpork, at six o'clock, every single day, no matter what.
