Search engine LookSmart
http://www.looksmart.com

Search engine LookSmart is a human-compiled directory of web sites. The company does operate its own web site, but this really isn't intended for the public to use. Instead, similar to Inktomi, LookSmart provides its results to other search engines that need listings.
LookSmart gathers its listings in two ways. Commercial sites pay to be listed in its commercial categories, making the service very much like an electronic "Yellow Pages." However, volunteer editors at the LookSmart-owned Zeal directory also catalog sites into non-commercial categories for free. Though Zeal is a separate web site, its listings are integrated into LookSmart's results.
LookSmart launched independently in October 1996, was backed by Reader's Digest for about a year, and then company executives bought back control of the service.
