Shelfari (Beta, of course) is “a virtual shelf to show your books” and “connect with your friends.” It’s an interesting concept and parts of it are well done, although some the limitations in organizing your shelf became apparent soon after I began to add books. It would be great to be able to reorder, or otherwise create categories (in ways other than using opinions or star ratings), but perhaps this is in the works as this site only launched this month.
Our shelf is at: http://www.shelfari.com/Ideum. For now, the books included are those that I thought would be useful for course I’m teaching at UVIC next month (The New Web: Interactive and Collaborative Technologies in the Museum World). I haven’t added much to our shelf in the way of tags or opinions to any of the books in the collection, but it’s a start. It will be interesting to see how things develop with Shelfari and with its closest competitor, the more established LibraryThing.
