'How to publish your own book' by Stewart Ferris is a handy little volume with plenty of useful tips. However it cannot be considered a complete guide to everything involved in publishing your own book - that would take more than 150 pages.
The best sections in this book are about marketing. Stewart Ferris talks about numerous options, many of which I hadn't thought about. For example I didn't know that Waterstones has a buyer who deals with self-published titles - so he'll be getting a copy of my book ('How to marry a Russian Wife') when it comes back from the printers.
One area that caused me a lot of problems when I decided to publish my own book was that of typesetting. What font? What size font? How much leading? How many lines per page? How many words per line? These are actually vital questions which can affect the readability of your book, yet Stewart Ferris doesn't discuss any of this.
However taken in the round there is plenty of useful information in this book, despite its gaps. It is clearly written and well laid out.
I would say it's definitely worth its cover price and I have no intention of putting my copy on e-bay; do I need to need to say more? Praise indeed!
