Content Curation World

LibraryThing is a full-powered online book cataloging application, capable of searching the Library of Congress, five national Amazon sites (Italy missing), and more than 690 world libraries.

Available since 2006, it offers anyone the opportunity to create a personal profile and then to search, find and add any book ever catalogued or published into your collections.

You can review, tag, rate, organize, sort, filter, group any book you find and you can also specify the perfect match cover (among the many published) that you want to use as reference. 

From the official site: "LibraryThing knows a lot about books and how books connect, providing some of the best recommendations on the web.

LibraryThing gives you library-quality data for your books, and is also full of social information.

Each book page shows you which members have the book and what they think about it — tags, reviews and even links to conversations about the book."

A free account allows you to catalog up to 200 books. A paid account allows you to catalog any number of books. Paid personal accounts cost $10 for a year or $25 for a lifetime. 

My comment: Stunning. I don't know why it took me so long to discover it, but this is an amazing resource for book lovers of all kinds wanting to curate and share their own favorite books. While the interface shows quite a bit of age in many aspects, the array of functions and useful options available to the user is simply amazing.
