Directories or Metaindicies

These sites can serve two purposes: they allow you to browse for information and allow you to perform a focused search.

My favorite metasite for patient information is Medlineplus (medlineplus.gov).  Other examples of a metasites are Yahoo! Medicine (http://dir.yahoo.com/Health/Medicine/), the Hardin Meta Directory (http://www.lib.uiowa.edu/hardin/md/) and HealthWeb (http://www.healthweb.org/).
