I've attempted to classify the books into sections but these are fairly loose and some may be included in more than one section. If you disagree about where they are, please let me know; likewise if you have any further titles you would like to add.

Many thanks to Ian Wilkins for his help with the information, Chris French for his support and advice, and all the Urglers who have suggested the books (and waited very patiently while I compiled this FAQ!).
Also thank you to Amazon UK for permission to use information from their website. For book purchase check out their website at http://www.Amazon.co.uk
