It can easy cost a thousand dollars to print 32 books.
For example, the fans of Jack Vance published an authoritative 44-set of his collected works, printed and bound similar to an encyclopedia. It was a nonprofit volunteer effort. The "reader's edition" was supposed to cost $1250 a set, but the price ultimately had to rise to $1500 to cover costs. The all-leather "deluxe edition" cost $3000.
