Internet Portals
A portal (or "gateway") site provides links to the best web resources for education and research on the Internet. Portal sites save researchers significant time in locating reliable web sites in any area of study.
Experiment with these portals to find the ones that you prefer. Bookmark your favorite for future use.
Librarians' Internet Index
Annotated subject directory of Internet resources selected and evaluated by librarians for their reliability and usefulness.
The Internet Public Library
A searchable, subject-categorized directory of authoritative web sites.
Intute
Hands down, this is my top choice of portals for high school and academic research. Intute directs you to the best Internet sites for education and research in the social sciences, arts and humanities, science and technology, and health and life sciences. Made by a network of UK universities and partners. Subject specialists select and evaluate the sites.
The WWW Virtual Library
This is the oldest catalog of the Web, started by Tim Berners-Lee, creator of HTML and of the Web itself, in 1991 in Geneva. 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 not the biggest index of the Web but is recognized as being one of the highest-quality guides to particular sections of the Web.
