This site looks pretty interesting: LuLu.com
It appears as if you can publish one or a thousand, as they are printed on demand. And they have services to help you distribute the book if you need, as well as some other services related to publishing. While I don’t have enough content written anywhere for a book…I do have quite a bit of art laying around that could be used for a calendar (another publishing option on lulu.com). If you are writing a book, you might want to at least take a look at the site, it could be a great starting point.
