The Internet has been compared to a flea market: a lot of junk, a few cool things, and some real treasures. The problem is finding the worthwhile information while minimizing the amount of time spent sifting through the junk. The key tools in this process are Web directories, search engines, and metasearch tools.

The key features of web directories are that (1) sites are organized into categories, so they are easy to browse, and (2) human beings look at the sites to determine if they are good and to decide the categories to place them. The sites listed below are general directories: they include sites on all kinds of topics.
About.com - directory of links for browsing and searching, combined with original contentLibrarians' Index to the Internet - directory of links for browsing and searching
Open Directory Project - directory of links for browsing and searching
Yahoo! - directory of links for browsing and searching
These directories include sites that are strictly for health, medicine, biomedical research and education, health care, and wellness. Don't look for sports scores with these tools, but they are incredibly useful when looking for health information.

MEDLINEplus - for consumers and patients; from the National Library of Medicine
MedWeb - for practitioners and consumers; from Emory University
Search engines are maintained by computer programs, with minimal human intervention. Search engines search a wider range of web sites than directories, but there are fewer quality-control mechanisms.
