Sweet Search is a Search Engine for Students.
It searches only the 35,000 Web sites that their staff of research experts and librarians and teachers have evaluated and approved. They constantly evaluate their search results and "fine-tune" them, by increasing the ranking of Web sites from organizations such as the Library of Congress, the Smithsonian, PBS and university Web sites.
SweetSearch helps students find outstanding information, faster. It enables them to determine the most relevant results from a list of credible resources, and makes it much easier for them to find primary sources. They exclude not only the spam sites that many students could spot, but also the marginal sites that read well and authoritatively, but lack academic or journalistic rigor. As importantly, the very best Web sites that appear on the first page of SweetSearch results are often buried on other search engines (copied from the About Sweet Search page)
