my 'read' shelf:
Ok, if you all don't know about Goodreads, you should. It is the most fabulous social networking site about books. It has widgets to add to Facebook or to your blog. It has features for making to-read lists, favorites lists, any kind of list you can imagine. Plus you can write or read reviews... and oh yeah, if you are a writer, you can self-publish there too. I can't say enough good things about it. I have included a widget that shows my to-read bookshelf in my right column under the "about me" information. There have been great discussions started on Goodreads.
There are also some students on Goodreads. It is a way for them to marry their online selves with their book-reading selves. Gotta love it.
