Can you help me compile a list of top resources on sexual identification issues?

As part of the Ally program, I have volunteered to compile a list of web and print resources on gender and sexual identification issues for the library at which I work. If you have used any resources in your own searching for identity or know of any particularly great resources, I would like to hear about them for my review. This is for a college library, but I would like the bibliography to be used by both students doing research or students who are questioning. Any input would be appreciated. Feel free to PM me if you prefer.
