The Annotated Pratchett
Spreading awareness of a very enjoyable site I found recently, The Annotated Pratchett - a site that explains many of the references in Terry Pratchett's books. It's particularly good for areas where one may have a specific lack of knowledge: I, for example, know essentially nothing about detective/cop shows from the 50s, 60s and 70s, but it turns out the early Watch books are riddled with references.
Of course, it doesn't have every reference by a long way, and sadly the entries for last few books haven't been populated (the site began back in the early days of the web), but it's still a brilliant distraction for any Pratchett fan.
