Everyone else covered the "beginner" books, so ill answer the other half of your question. The "master" books contain more recipes. Harder recipes, suitable for master craftspeople. The Master 1 and 2 books(plus the demi-material book) are level 50 1-4star recipes, Master 3 and 4 are level 60 1-4 star, and Master 5 and 6 have the level 70 1-3 stars(with 4 star to be added in the next patch).
