OK, I'm really going to go out on a limb here. I think Research Guy is either not aware of the changes in publishing going on or he is ignoring them. The main publishers are in cahoots with the brick and mortar stores and would like you to believe as Research Guy that POD is not the way to go. Well, I've got news for people like Research Guy: this is an internet world. I'm an old duffer and even I recognize this (one reason I'm here at Absolute Write). In twenty years (or maybe less) everyone will have something like a Kindle, the brick and mortar bookstores will be gone, and the main publishing firms will also be gone. I can now read most major newspapers around the country on a Kindle too, so newspapers will be gone. (Good riddance, too -- we need to save a few trees.) Unfortunately Amazon needs some competition to bring the Kindle price down.
In reference to Morgan Freeman, I love the guy, but gee folks, I can't wait twenty years -- I'll be dead. Granted, most POD books don't get into bookstores (Infinity does), unless you, the author, put them there. I published my first novel with Xlibris and had a painful experience on many fronts (it's on Amazon and Barnes and Noble, but they don't do any marketing). Infinity seems to have avoided all the problems I had with Xlibris, including having a book return policy (which is why book stores don't like PODs).
Bottom line: I think POD is the way to go. I fully recognize that I have to market my own books -- and I plan to do so...on the internet. Unless you're Stephen King or someone equally famous, you will have to market your traditionally published book anyway. So why not make it so you're completely in control?
