The Memory Book

The Memory Book: The Classic Guide to Improving Your Memory at Work, at School, and at Play by Harry Lorayne & Jerry Lucas

This (as the title suggests) is one of the classic memory books. It is well written, and Lorayne makes every technique he describes clear and easy to understand. The book also encourages you to work along with the text, testing and practising the systems as you go. The book is a thoroughly enjoyable and educational read... and comes highly recommended.
