• Introduction
• We have witnessed a tremendous growth in the
  quantity of printed
• publications - books, journals, conference
  proceedings.
• Today Internet and its related technologies
  like WWW has resulted
• in the rapid proliferation of electronic
  information.
• From its origin in 1991 as an
  organization-wide collaborative
• environment at CERN - European laboratory for
  particle physics, for
• sharing research documents in nuclear
  physics, Web has grown to
• encompass a variety of information sources -
  electronic journals,
• pre-prints, technical reports, databases,
  library catalogues, educational
• materials, career sources, information on
  organizations, associations
• and so forth.
• The growth of the Web has proliferated so
  rapidly and in so many
• areas of society, we now recognize that
  'taming the Web' has become
• an urgent necessity, if it is to mature into
  a reliable and effective
• communications medium.

7

• Because of this rapid growth, librarians and
  information professionals
• are developing a variety of solutions in
  bringing the explosion of Web
• resources under control.
• It is our(librarian's) responsibility to
  provide systematic access to
• information available on Internet, by
  classifying the same depending
• on its inherent characteristics.
• With the rich experience gained at NCSI in
  building resource
• catalogues in Science, Engineering and other
  allied fields, we have
• identified a set of Internet Resource Types in
  which most of the
• Internet resources can be beautifully
  accommodated and very well
• structured.
• We attempt to provide a brief overview of the
  various types of
• Information Resources available on Internet in
  Science Technology,
• Business and Social Sciences.

8

• Resource Types in Subject-based
• Information Gateways
• ADAM - adam.ac.uk/adam/index.html Art, design,
  architecture
• and media information gateway is a searchable
  catalogue of 2390 Internet resources that have
  been carefully selected and catalogued
• by professional librarians for the benefit of
  the UK Higher Education
• community.
• ARGUS Clearinghouse - www.clearinghouse.net/
  Provides a
• central access point for value-added topical
  guides which identify,
• describe, and evaluate Internet-based
  information resources.
• Chemdex - www.chemdex.org/ An international
  directory of
• chemistry on Internet from Dept of Chemistry,
  University of Sheffield.

• Resource Types in Subject-based
• Information Gateways
• EEVL - Edinburgh Engineering Virtual Library
  
• www.eevl.ac.uk UK gateway to quality
  engineering information
• on the Internet
• Galaxy - galaxy.einet.net Galaxy originally a
  prototype
• associated with the DARPA-funded
  Manufacturing Automation and
• Design ngineering (MADE) program, is the
  oldest
• browsable/searchable web directory.
• SOSIG - sosig.ac.uk/ Social Science
  Information Gateway
• helps to locate high quality sites on the
  Internet, relevant to social
• science education and research.
• Vlib - The Virtual Library, www.vlib.org/
  oldest catalog of the
• web, started by Tim Berners-Lee, the creator
  of html and the
• web itself.
