On-demand publishing has made it easy peasey to get your book in the hands of people who want it. Createspace.com has a variety of MS Word book templates and sizes you can download in industry standard book sizes.

Publishing your book is a two step process with them. First is to upload your MS Word doc as a PDF, then you'll upload your cover as three images: front, back and spine.

They'll also get you an ISBN so you don't have to buy an expensive block of five ISBNs from whatever company manages that.

They also have a program where they will make your book available to a wide variety of extended distribution partners. Your keep for each sale through Amazon and extended partners is around 1/2 the sale price, which is pretty much an industry standard. In retail sales, it's call the "keystone" or 50% profit margin.

Personally, I do much better selling through my personal website at [link to www.catawbacoops.com.] I get to keep a significantly greater margin on my books, but I have to work harder to sell them as well (Google AdWords, SEO, etc).
