Selective Web Indexes
The following sources offer access to sites that have been selected by librarians, educators, and information professionals. They are often helpful if you are finding too many pages using standard search tools, or are not finding material of substance.
The Internet Scout Project
One of the best-known guides to quality information on the Web, especially of potential use to students and educators. The Scout Report Archives include over 13,000 evaluative entries on websites in all subject areas, and is searchable.
The result of a merger of the Internet Public Library (IPL) and the Librarians' Internet Index (LII), ipl2 is a searchable annotated collection of resources selected by librarians. Although sites are selected primarily for the general public, many are of use to those in higher education as well.
The WWW Virtual Library
Started by Tim Berners-Lee, the creator of html and the web itself. Sections of the WWWVL are maintained by volunteer experts.
