Dmoz's Open Directory Project is the largest, most comprehensive human-edited directory on the web. It is owned by "Time Warner" and constructed and maintained by a vast, global community of volunteer editors, and is truly unique in many ways.
It is a large, categorized directory of websites and pages, which is staffed by volunteers. Every website and page that is added to the directory has to be manually reviewed before it is included. Since its index is manually constructed and edited, categorization and relevancy is superior to any other index of its kind and equally as unique, is the fact that this data is open and free to the public for replication. As of July 2005, ODP had about 4.6 million listings organized into over 580,000 categories derived from the contributions of some 69,000 editors.
