Good list of reading! I too started my "collection" with
Beekeeping for Dummies and quickly added
ABC & XYZ of Bee Culture. Since then I've heard/read on forums that the
Complete Idiots Guide to Beekeeping is a bit better than the Dummies, but at the end of the day you probably can't go wrong with either. The latest resource to add and has been suggested/required reading in many Master Beekeeping Programs (at least here in Florida) is Dewey M. Caron's book
Honey Bee Biology and Beekeeping. Mr. Caron has a lot of street cred with the Phd crowd and certainly "knows his onions". I will be adding it to my beekeeping resources soon.
As far as Michael Bush, his website is the same as his book and he freely admits this. His self-published book is a hard copy compilation of his open website information. Also, Mr. Bush is a great resource for the beekeeping world and I give him a lot of credit and respect for making himself available. Much of what he has done is resource the public domain knowledge base from older material that is not copyright protected. Such as
Better Queens by Jay Smith and C.C. Miller's;
50 Years Among the Bees. Nothing wrong with wisdom and techniques from the 19th and early 20th centuries (much of the queen rearing techniques are still the same), but overall conditions then and now are VERY different. Still good reading and resources.
A great overall beekeeping resource is Cornell University's
Hive and the Honeybee website. I recommend anyone looking for resources to delve into the highly organized resources there and dive for the plethora of pearls contained there in.
