The Open Directory Project is the largest, most comprehensive human-edited directory of the Web. It is constructed and maintained by a vast, global community of volunteer editors.
The Open Directory uses volunteer editors to catalog the web. Formerly known as NewHoo, it was launched in June 1998. It was acquired by Netscape in November 1998, and the company pledged that anyone would be able to use information from the directory through an open license arrangement. Netscape itself was the first licensee. Netscape-owner AOL also uses Open Directory information, as does Google and Lycos.
The web continues to grow at staggering rates. Automated search engines are increasingly unable to turn up useful results to search queries. The small paid editorial staffs at commercial directory sites can't keep up with submissions, and the quality and comprehensiveness of their directories has suffered. Link rot is setting in and they can't keep pace with the growth of the Internet.
Instead of fighting the explosive growth of the Internet, the Open Directory provides the means for the Internet to organize itself. As the Internet grows, so do the number of net-citizens. These citizens can each organize a small portion of the web and present it back to the rest of the population, culling out the bad and useless and keeping only the best content.
The Open Directory follows in the footsteps of some of the most important editor/contributor projects of the 20th century. Just as the Oxford English Dictionary became the definitive word on words through the efforts of a volunteers, the Open Directory follows in its footsteps to become the definitive catalog of the Web.
The Open Directory was founded in the spirit of the Open Source movement, and is the only major directory that is 100% free. There is not, nor will there ever be, a cost to submit a site to the directory, and/or to use the directory's data. The Open Directory data is made available for free to anyone who agrees to comply with our free use license.
The Open Directory is the most widely distributed data base of Web content classified by humans. Its editorial standards body of net-citizens provide the collective brain behind resource discovery on the Web. The Open Directory 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.
