Daniel Poynter is a self-styled expert on the self-publishing world. He has written and self-published many books which he claims have sold than a million copies worldwide. He offers a self-publishing consultancy service, and has a web site packed full of information for the aspiring self-publisher. And he's not alone: a quick Google reveals thousands of websites which suggest that self-publishing is a good route to success.
Daniel Poynter offers for sale a list of his own self-published books, and he also sells "My Book Project In A Binder" (you'll need to scroll nearly all the way down to find it), which is priced at $297 and seems to consist of a zippered three-ring binder with a CD, some paper and coloured dividers. He is nothing if not resourceful.
However, in his zeal to promote self publishing as a viable route into print (and, by doing so, to sell a few more copies of his self-published books about self-publishing) Mr Poynter has allowed a few errors to creep onto his site. In this PDF (which will download if you click the link), Poynter lists several authors who he claims are self-publishing successes. But in many cases the writers he names didn’t actually self publish: either publishing was a whole different business when the writers were alive (like William Blake), or they didn't self-publish anything (like John Grisham). And while it's true that Mark Twain did self-publish he almost bankrupted himself in the process, and then had to undertake a lecture tour to pay off the resulting debts which nearly killed him. So when you read sites like Dan Poynter's, be very sceptical about some of the claims you find: and remember The Big Question About Self-Publishing Successes.
