Social cataloguing tools
[|LibraryThing]

Users (informally known as //thingamabrarians//, a term coined by contributor RJO) can catalog personal collections, keep reading lists, and meet other users who have the same books. While it is possible to keep a library catalog private, most people choose to make their catalogs public, which makes it possible to find others with similar tastes. Thingamabrarians can browse the entire database by searching titles, authors, or tags generated by users as they enter books into their libraries.
 * LibraryThing** is a prominent social cataloging web application for storing and sharing personal library catalogs and book lists.
