Johnathon Clifford coined the term vanity press back in '59. He has a site (link).
Quote:
If you cannot find a mainstream publisher to publish your work at their expense, you must look on the whole process of publishing not as money invested to make you a return, but as money spent on a pleasurable hobby which you have enjoyed and which has provided you with well-manufactured copies of your book.

Ceci n'est pas un seing.
