As some of you already know, WorldCat is an online library catalog that allows you to search the holdings of libraries everywhere, rather than just your own public or academic library. Before, however, the full version of WorldCat was only available through a library (that is, if I wanted to search WorldCat, I'd have to go to the University of Minnesota Libraries' home page and click on a link available there). However, it seems that WorldCat is now available on the public Internet. I looked at the "About" page and it seems that there are several features still unavailable on this version, but it looks like it could be really useful anyway. Check it out and let us know what you think.
