The side of the page features a new block with content from Library Thing. Library Thing is Tim Spalding's tool for allowing bibliophiles and compulsive organizers to have a single, online, place to keep track of book collections. The site favors tagging via a free-taging ala del.icio.us over a Library of Congress subject heading. It is a nice tool for putting a library together. There will, undoubtedly, be some things that come from a few days of working with it that will make it more valuable. One of the first would be the ability to comment on and tag books that are not in my library.
