From the oddbook site , it's: "a little php app to help you keep track of your obsessive reading... [which] will let you keep track of your books via a series of web forms. Authors are accessed via pulldown list so no author typos munging up your data. You can sort your booklist by month, by author, title, or rating. You can also mess with the CSS to make it look however you want." If you've enjoyed keeping up with Greg's and Jessamyn's respective reading, well, now we can enjoy keeping up with yours too.
