I've got a post over on Operation Awesome today, talking about cover art for books.
And also wanted to direct you to a post on David Gaughran's blog with some new dirt on AuthorHouse, and how they're using the Penguin Random House merger to try to lend some legitimacy to their practices. The most confusing thing about all of it is that AuthorHouse now has so many subsidiaries, it's difficult to keep track of them all. There's also a thread on Absolute Write going back to 2002 with complaints about AuthorHouse's practices.
It's just another reminder to do your due diligence if you're looking for a way to self-publish your book. This is not the way to go! I had someone in my writer's group fall for this and he was out over $2,000 for a book that was riddled with errors (most of them on the "publisher"'s side) that was unsold and unsellable.These are the kinds of practices that give legitimate publishing services a bad name.
