W3 Catalog was an early web search engine, first released on September 2, 1993 by developer Oscar Nierstrasz at the University of Geneva. The engine was initially given the name jughead, but then later renamed. Unlike later search engines, like Aliweb, which attempt to index the web by crawling over the accessible content of web sites, W3 Catalog exploited the fact that many high-quality, manually maintained lists of web resources were already available. W3 Catalog simply mirrored these pages, reformatted the contents into individual entries, and provided a Perl-based front-end to enable dynamic querying.
