Then click on Search by Subjects. Click on the Virtual Library, then click on a topic of interest and explore the links. If you don't see the topic you want listed, scroll down to the bottom of the site, then click on the link to the alphabetical list of topics. If you wish, explore some of the other links under Searching by Subject, from the GGU University Library Search Page. Unlike the Virtual Library, however, Yahoo does not have subject specialists actively seeking and organizing sites by subject.

When people ask me what books I recommend they read on Internet Searching, I refer them to this site. Scan down and click on the Table of Features of the Boolean Logic-Based Search Tools.
