Yep...there was a time before the internet when you went out to the yard and saw something strange and your choice.....go in the house open your books and see if you figure it out. So the two books that got me thru all that have both been mentioned several times...ABC-XYZ and How to by Taylor. I would agree that you can not take everything as gospel for instance most all the newer books including Natural Beekeeping - Conrad mention using treatments as a matter of fact....I don't agree with that. Anyway...get some books, subscribe to Bee Culture and American Bee Journal, read on here, MB website, and everywhere else you can find, then go out and enjoy because you will learn most by doing.
