The Web is a wondrous thing! I have this software (Bookster) that I thought was great because I could create a catalog of books I own and it would automatically pull up cover pictures and basic info about each book from the Library of Congress or Amazon.com. But the big drawback was that I never had it with me when I was looking for a book in the library. Did I have this book--or not? LibraryThing is another "social software," Web 2.0 utility that lets you create a catalog of your books on the web, making all the possibilities for collaboration available. I can look up my list anywhere there is web access. I haven't tried all the other parts of it yet--a blog, a recommendation list, import and export functions, books groups, etc. It does make use of the folksonomies I blogged about on Friday. Give your books "subject headings" and you can find others with the same headings. A librarian's dream!
If you have any need to put some organization into to your life, try it. JS
