If you don't have any books, this one might be a good one to have for a couple of reasons. First, it covers everything from what you need to know about bees, to actually using a Top Bar Hive. Second, it's free.
The book is actually a Peace Corps manual on keeping bees in tropical regions and, as you might expect, it leans towards simplicity and low-cost methods.
It is available as a PDF, but it's 220 pages long so make sure to have a fresh cartridge or ink tank in your printer! Download the file 32.771.pdf.
Not on our blogroll, because it's not strictly about beekeeping, but there's some really inspiring stuff at A Growing Sense. Written by an volunteer with the Peace Corps in The Gambia, just type "bees" in the search box and you'll find lots of interesting posts.
