This directory of links to online exhibits covers the gamut from the biosphere to Rembrandt, from frogs to Freud, offering ratings and annotations of the Websites. One can use the keyword search engine to search for a specific subject or browse using subject headings that break down into more specific terms. The annotations are fairly informative, and the ratings of sites seem to reflect their attractiveness and critical mass; but we found some of the topic listings fairly idiosyncratic, such as Dolphins, the Oracle of the Sea (a Thinkquest site) listed under Veterinarian Medicine. Still, given the number and breadth of quality sites featured, this would be an excellent resource for educators seeking ways to integrate the Web into their teaching or even high school and college students looking for good research topics. Its attractive, easy-to-use presentation makes it a fine resource for younger students as well. This site was designed by Michael Douma Productions with initial support from the National Science Foundation (Division of Undergraduate Education).
