:There are two things I need to know.  One.  Whether the best current method of making books creates a thousand copies at a time or one copy at a time.  Two.  Whether there's a book or class of books where, if you could produce thousands of them, you could sell enough of that kind of book to buy enough of the food you need.  If either of those questions has the wrong answer, I can try to remember half-remembered lessons on how to build Civilization if it vanished overnight, talk to your metal-workers, and see if I can remember the next step up from your current metallurgy.  Do you already have 'steel'?:
