Does anyone have tips on self-publishing a book? I have the majority of the book done and on word processing. I am going to print on for a 3-ring binder and have some readers make suggestions. If I get to the point of a bound book, I would like pointers or a resource to do this as inexpensively as possible..

It's free as an e-book on Amazon. There's a reasonable charge for a print copy.

Have it proof read by professional. Many publishers require specific font and layout

Print Publishing is expensive. I would recommend going with an E-book. This article discusses ways to secure the book:

If the book generates interest, then you may get a publisher to do a print run.

Check out http://www.lulu.com/ to get print books with reasonable cost.

I'm not affiliated with Lulu in any way. I suggested them to my brother-in-law several years ago and he's been happy.

Good luck,
