Regardless of your individual view of self-publishing, it seems to me to be on the rise. I don't have a ton of experience with self-publishing, but I have some. In any event, a friend and an aspiring author asked about self publishers a few days ago and I compiled a list with some links for him. Here's the list...
Dog Ear Publishing
Booksurge (Amazon owns this one)
Wheatmark Book Publishers
If you are interested, check them out. I don't want to recommend a specific one because I don't have experience with all of them. Check online forums and you can get info on most of them. When I do that, most of the "complaints" I see are really about self-publishing and not about the self-publishers. If you go this route, just make sure your expectations are realistically set and a lot of the complaints will go away.
