from the introduction:
As a game master you may well find yourself in a situation where the players wants to examine some library of no importance to the story itself. Rather than tell them this, you can use some of the following books. Some of the information will reefer to a "Personal timeline". This is a piece of paper you can make for characters with the history skill, which contains information, in the form of a timeline, showing what a character has learned knowledge about. Just skip this rule if you don't like it, and instead tell the player what happened on a specific year, when they read some of the books.
The document is mostly setting enrichment material (i.e. *fluff*) but describes a few books that refer to WFRP 1e spells or creature statistics. It could easily be used with any other edition with minor changes.
