I have just discovered the Open library - this was what took my attention, but there is much more. If anyone is using it I'd love to hear from you.

Get Thee to a Library!

By george oates

For our first big release of 2011, we’d like to introduce you to a couple of new bits and pieces on Open Library:

A new home page design
New Homepage When we launched the site redesign almost a year ago, the home page was trying to make it clear that it was possible to edit the Open Library site, and that we welcome your contributions. You might remember the cheeky "Ever wanted to play librarian?" phrase. Now that the new design has settled somewhat, and we have a great level of activity across the site, we wanted to shift the focus again, to make it clearer that you can actually get to books as well. Not only over 1 million free eBooks, but also our small, but growing Lending Library.

So, the new home page displays 3 new "carousels" that display an assortment of free eBooks to read, a small curated selection of titles from the Lending Library, and Version 1 of a new "Return Cart" feature, that shows you eBooks that have, well, been recently returned.
