About VL PSI

“The WWW Virtual Library (VL) is the oldest catalog of the Web, started by Tim Berners-Lee, the creator of html and the Web itself, in 1991 at CERN in Geneva, Switzerland” (see About the Virtual Library).

The WWW Virtual Library is the direct descendant of the original Overview.html page on TBL's server in Geneva. This itself was linked to from the Web's main-page http://info.cern.ch/hypertext/WWW/TheProject.html (that location no longer exists and the link is to an archive copy at W3C). The Virtual Library's server is now (2005) in Geneva again, a few kilometres from the original site of the Web's creation in 1990-92.

The Published Subject Indicators VL was a new entrant to the collection of (then) some two hundred plus existing VLs, in November 2005.

At that time the maintainer wrote: “The author/maintainer having spent some time 'scrabbling' around the Web to find PSIs decided to try and compile a list (and to add some PSIs of his own, created for a broader project).
There also seems to, currently, be a debate as to whether PSIs should be 'distributed' (exposed to 'Darwinian selection') or 'centralized'. An unofficial listing is a 'contribution' to that debate.

A PSI-specific search engine is installed and in place … once there is some clarity as to how authors will lay out their PSIs (so that the advantages of a dedicated search engine can be used!) then it that will become operational.

You may contact the maintainer with any comments or suggestions.
