I'd love to hear from you via e-mail or Twitter. I'd love somewhat less to hear from you via other social networking sites - I have accounts on Facebook, LinkedIn, GoodReads, etc. but don't use any of them regularly, so please don't be offended if I don't immediately approve your friend request or something.
If you'd like to send me books or other materials for review, please e-mail me for a mailing address you can use. Receipt of materials does not guarantee a review, but I'll do my best. Thanks!
