Librarything allows users to create an online catalog of the books they own or have read. A user can tag and rate all the books he adds to his personal library. The social aspects of this network give the user the opportunity to meet likeminded people and find new books that match their preference. The popularity of the system has resulted in a database, containing over 2 million unique works collaboratively added by more than 200.000 users. Currently we are aware of no other open network that contains this amount of collaborative tags and ratings.

We have collected a trace from the LibraryThing network containing 25.295 actively tagging users. As expected we see that the number of books in the users’ catalogs follows a power law (see Figure 5a.). After pruning of this data set we retain 7564 users that have all supplied both rating and tags to at least 20 books. All books are annotated by at least 5 people resulting in 39.515 unique works.
