Social cataloging application

A social cataloging application is a web application designed to help users to catalog things—books, CDs, etc.—owned or otherwise of interest to them. The phrase refers to two characteristics that generally arise from a multi-user cataloging environment:

• The ability to share catalogs and interact with others based upon shared items;
• The enrichment or improvement of cataloging description through either explicit cooperation in the production of cataloging metadata or through the analysis of implicit data (e.g., "People who like X also like Y").
