I was scanning the shelves at Borders and must say most of the books on self-publishing do not look all that useful. Then I saw the first line of a book by Robert Holtcalled "How To Publish, Promote, and Sell Your Own Book".
"This book has been prepared because I found a need and filled it."
The book itself is previously self-published but now produced courtesy of St. Martins Griffin--and the author has written multiple successful self and traditionally published books. It is a book from the eighties and so well behind the eight ball on modern developments but the fundamentals haven't really changed. I'll write a full review when I get to the end.
If you can recommend any useful books on self-publishing please let me know.
