Have you taken a look at how many business books there are?
The choice is overwhelming in a good store like Waterstones in the UK or Borders in the USA but it gets even worse when you take a look at what Amazon have to offer.
Here is a list of books I recommend to small business owners in no particular order.
General Small Business
The E Myth Revisted by Michael Gerber – this book could change the entire way you think about your small business. Love it or loathe it, the book is subtitled “Why Most Small Businesses Don't Work And What To Do About It” and I ‘m certain it will make you think. (Link to my book review on my Business Coaching blog.)
