Writing a book......

[seakdivers]

Sun Sparkz - check out http://www.iuniverse.com/ a friend of ours published a book through them. They are what is considered a "vanity" press.

My husband has published three textbooks through Elsevier Science, and that's a whole different ballgame. You have to get approval before you even start writing the book, and once they have signed on you are contractually bound to get it done in the way you proposed. He just finished his fourth one, and has a fifth in the works.
It's a lot of work, but it's worth it!
