This business is focused on getting money from the author looking to self publish. Much of what it does is not about publishing it's a scam.
I suspect thousands of people have been taken advantage of by this company. The ethics is that of an Internet Troll that lives off users of the Internet by fraud and deceit. This company wanted me to pay for analysis or evaluation of books I had already published that were best sellers.
Xlibris wanted to sell be author tools and seminars. What is surprising to me is that this business hasn't been shut down by any government or agency.
Reason of review: They're scammers.
Preferred solution: I use 48HR Books and sell on my website, Ebay, and Amazon.
Xlibris Cons: Attempted to defraud me.
