Since 1995, Refdesk is a free and family-friendly web site that indexes and reviews quality, credible, and current web-based resources.
Refdesk has three goals:
(1) fast access
(2) intuitive and easy navigation
(3) comprehensive content, rationally indexed.
The prevailing philosophy here is: simplicity.
Refdesk’s database is on three levels: quick, studied and deep.
For a more studied approach: Newspapers – USA & Worldwide, Search Engine Resources, Internet Help, and Writing Web Documents.
For an in-depth exploration: Facts Encyclopedia with over seventy volumes of indexed subjects and Facts Subject Index with twenty-four subject categories.
