I find my self spending so much time swapping books that it is cutting into my reading time. It started on just trying to fill the gaps in my unfinished series and has ended up with my finding lots of folks I have never read before. I am now addicted to book swapping sites.
Point of discussion, I use
Paperbackswap which is my favorite and seems to have the biggest selection.
Book Mooch which is easy but doesn't seem to get the traffic or books like Paperbackswap.
TitleTrader which allows you to list just about anything and trade it for books. (I am divesting myself of a wide range of computer parts in exchange for books.)
Swaptree which is my least favorite, hardest to use and zero communication from the site but they do allow you to rade CD's and DVD's for books.
So where do you swap your books and how do you like them?
