Open Directory Project is the largest, most comprehensive human-edited directory of the Web. Constructed and maintained by a global community of volunteer editors, listings are also approved by real people, which means that every people-approved listing is spider free.

The Open Directory also powers the core directory services for the Web's largest and most popular search engines and portals, including Netscape Search, AOL Search, Google, Lycos, HotBot, DirectHit, and hundreds of others.
