The Nice and Accurate Prophecies of Agnes Nutter, witch
From Discworld & Terry Pratchett Wiki
A book unique among all books on prophecies and the future in that it is completely accurate to the letter. Written by Agnes Nutter, it recounts all of history's most important events up to and including the Apocalypse. However, there is an idiosyncratic twist in that while all the described events are 100% accurate, they are historically important only to her linear descendants. Thus, an entry that can be dated "22nd November 1963" says nothing about an assassination in Dallas, Texas, and everything about the need to avoid falling roof slates in Hull. This is because John Kennedy is not a descendant of Agnes, but Anathema's father, who was visiting Hull at the time, most definitely is, and needed to be warned about a more immediate risk.
In some ways, it is a spiritual link between Anathema and her ancestors, as they have throughout the book scrawled their own notes next to the passages. Including some encouragement on their parts for Anathema and Newton Pulsifer to enter in a relationship with each other.
The Device family have devised a complex reference system, with cross-references and all printed on small cards. It is easy to see why the family are extremely good at crossword puzzles...
