There are a million online resources dedicated to Beekeeping. Here are some that we have found to be very helpful.
Bush Farms, Michael Bush's web site. Fantastic resource.
The Knox-Lincoln County Beekeepers Association, a chapter of the Maine State Beekeepers Association.
Beesource.com This is a GREAT SITE. Lots of information and a very active bulletin board and chat system. Lots of very knowledgeable people on board. I spend a lot of time here.
Beemaster.com Yet Another GREAT SITE. Again, lots of information and a very active bulletin board and chat system. I'd like to spend MORE time here, if I had more time.
Beekeeping mailing list at Yahoo. A pretty busy mailing list- mostly "hobbyist" beekeepers which IMHO doesn't mean anything anymore.
Organic Beekeepers mailing list at Yahoo. A very busy list, relatively- dedicated to Organic Beekeeping in general and discussions on small-cell beekeeping in particular. Populated by some very knowledgeable folks. My favorite list
BEE-L Mailing List.Relatively busy list frequented by many commercial beekeepers, but with a good range of people on it. This list has been around a long time and has a very good and easily searchable archive. I don't post there much, but I read it.
