I picked up this book by Tom & Marilyn Ross through inter-library loan. I am in the middle of a couple of projects that are going to be self-published. This book had good reviews on Amazon, so I thought it might be helpful.
The book could be helpful, but unfortunately it is very dated. Granted, the latest edition is 2002 and it is still dated. The book gives general business advice, writing advice, and basic publishing advice. Perhaps one can learn to not lean to heavily on internet addresses and sources by reading this book. The authors included many URL's that are no longer any good. A subject like this requires a new edition every few years - the business of publishing is in a constant state of flux. If you can ignore the internet addresses and computer advice, you may find some helpful advice. Still, the better book is by Dan Poynter.
