World Wide Web Virtual Library
The World Wide Web Virtual Library was the first index of content on the World Wide Web and still operates as a directory of e-texts and information sources on the web. It was started by Tim Berners-Lee creator of HTML and the World Wide Web itself, in 1991 at CERN in Geneva. Unlike commercial index sites, it is run by a loose confederation of volunteers, who compile pages of key links for particular areas in which they are expert. It is sometimes informally referred to as the "WWWVL", the "Virtual Library" or just "the VL".
WorldWideWeb
WorldWideWeb (later renamed to Nexus to avoid confusion between the software and the World Wide Web) was the first web browser and editor. It was discontinued in 1994. At the time it was written, it was the sole web browser in existence, as well as the first WYSIWYG HTML editor.
