The Book of Books - Les Krantz, Tim Knight (reference - literature)

This book is full of helpful suggestions for what to read next. The sections are organized by topic, and under each topic is a list of books or authors to try. Some of the categories are straightforward, such as American West Novels. Others are more inventive, such as New Yorker Contributors. I like that this book covers some non-fiction as well as literature - there are entries for Animal Behavior and Science, amongst others. The Book of Books would make a nice gift for any bookworm.
