This is a neat site.

What is LibraryThing?

Enter what you're reading or your whole library—it's an easy, library-quality catalog. LibraryThing also connects you with people who read the same things.

What's good?

* Searches Amazon, the Library of Congress and 60 other world libraries.
* Get recommendations. Connect to people with similar libraries.
* Tag your books as on Del.icio.us and Flickr.
* Put your books on your blog.
* Export your data. Import from almost anywhere too.

If you want to explore the site, try the zeitgeist and the BookSuggester. For example: enter From Dawn to Decadence and you'll get a recommendation for The Metaphysical Club.

[Looks rad, but i wonder if there's any way for me to upload my Delicious Library file to it?

I spent a lot of time populating DL -- though i've since slacked and it's woefully out of date -- it'd be nice to start from there... -k]
