I've wanted to put together a nice, big hardcover pet cockroach book for a few decades but it was not possible till a few years ago without going bankrupt. The problem was you could never sell enough copies to pay the basic print costs of a traditional print run but print on demand technology has improved greatly. I have been working on a text for some years now and was wondering what other roach hobbyists thought about splitting a book into two parts to get the cost down to 35 versus one big, complete one at 60. I wonder if it's possible to sell even a few books at the higher price. I may not have an actual say in the matter.
