Buying Books for Others

I love buying books. Books have always been my biggest shopping vice (or virtue). But sometimes buying books for other people can be almost as much fun as buying for myself. It makes me look at books I might never have been exposed to otherwise, and it sends me off on those wonderful "people who bought this book also bought this book" searches. So, here are some of the books I've either looked at or ordered when purchasing books for family members. Some of these have now ended up on my own wish list.

Have you found any surprise gems when book shopping for others?
