Xlibris is another self-publishing house, and though I have not used it myself, I know people who have and love it. Unlike Lulu, in which most of the services are purchased seperately (though they do have packages), services at Xlibris are bundled. Many of them look really nice. You can see them here. I don't think I'll be using them in the short term. I'm trying to get The Steel Dragon trilogy to a traditional publisher, and my next book His Robot Girlfriend, I plan to distribute free. Beyond that though, I may use Xlibris. If you have had experience with them, good or bad, leave a comment.
