Morris Rosenthal over at his Self Publishing blog is offering cold, hard cash for copyrights, publishing businesses, and websites. If you have decided that enough is enough and you are ready to cash in your chips, you might want to wander over and have a chat with him.
One caveat: Rosenthal's not really interested in taking over losing propositions. It absolutely does not matter if you spent $20,000 on a book, if you have never made a profit. Likewise, I am sure, with other assets that have never made money.
That being said, go take a read.
