This 700 page book is crammed with beekeeping information. It is very detailed in bees' anatomy and behaviour, complete with diagrams. Detailed explanations of how the bees process honey. Sections on how to deal with absolutely every aspect of beekeeping, all showing diagrams and drawings to reference how to do it (bees biology, brood, creating nucleus colonies, feeding, building hives, diseases, extracting honey, plants for bees, how to capture wild hives, recipes, etc., etc., etc).
I've seen this book offered (published originally in 1947) by just about every major beekeeping supplier and its also highly recommended by beekeepers as well.
You might need magnifying glasses to read the small print but this book is absolutely worth the investment. It's the most complete beekeeping book I've ever seen.
