Starting to analyze book costs.
Use of books clearly doesn't fit neatly into our tables for anvil use. I'm trying to analyze the new rules.

General Notes
(accumulated as I discover things)


 * 1) Using books is cheaper than combining items.  This is as it should be, since we already paid for books at the enchanting table.
 * 2) Naturally, we're not paying repair costs, either.
 * 3) Interestingly, we don't seem to be paying base-value costs for the target item.
 * 4) Combining two books costs the same as combining a book with an item.

Iron picks
Starting with iron picks and the tool enchantments. All the ingot and sacrifice-repair stuff I've tried matches the current table, so I'm focusing on books, combining various levels of enchanted pick with various books:

Efficiency: 0+N: 2, 3, 5, 6, 8 1+N: 2, 2, 4, 5, 7 2+N: X, 3, 3, 4, 6 3+N: X, X, 3, 3, 5 4+N: X, X, X, 4, 4 5+N--> X, X, X, X, 4 N+ Silk Touch: 8, 8, 9, 9, 10 Silk Touch+N: 5, 6, 8, 9, 11

Unbreaking: 0+N:2, 3, 5 1+N: 2, 2, 4 2+N: X, 3, 3 3+N: X, X, 3 N+Silk Touch: 8, 8, 9 Silk Touch +N:  5, 6, 8

Books on Books
Combining two books. Fortune and Silk touch result in the same book as the target slot, the others combine in the same way as correspondingly-enchanted items. Yep, multiple-enchant books can be produced.

Table: tool enchantments
The rows indicate the target item (book/tool), the columns indicate the book that's sacrificed.
