The Collins Beekeeper's Bible is definitely worth a read if you are thinking of getting into beekeeping.

A lot of information on bees as a species and their habits. Most of the information in here is about keeping bees in a standard square commercially bought hive, versus a top bar hive or something more primitive. It is a good intro into beekeeping in general.
