Looking for ways to be convinced not to publishing your book with POD publishers? Author Simon Haynes has lots of reasons for you:

There are good books being published using POD means, but the vast majority are works which, before the advent of the technology, would have languished in slush piles. Many POD publishers will accept anything if the author is willing to pay the bill, and that means book stores have been deluged with people trying to get POD books onto their shelves. The last thing they want is for their regular customers to end up with someone's first draft, and as there's no way they're going to personally read everything they're offered they generally refuse to take POD books point blank - although they will order copies in to fill firm orders.
