Books Worth a Look is a place to add your favorite books, and most importantly tag them and rate them, and then review them and discuss them on Oort-Cloud.
There is also a "New Books" menu on the right, so you can keep up with new additions.
Try it out, and be sure to report any errors, and give lots of feedback and suggestions for innovative ways to utilize the new archive.
I am thinking of posting a couple book reviews of books which I have found immensely useful for writing here. Do you folks think it would be helpful at all?
