I've been on BC quite a while and, unfortunately, don't read or release as often as I should. However, if you're interested in a book on my "available" shelf, feel free to P.M. me. I'll usually send the book (if I can find it!), either for a trade, for
postage, or just for fun (a RABCK).
I am also a member of the BookCrossing team on Kiva (http://www.kiva.org/team/bookcrossing). Feel free to check it out and join us there.
