- Medical World Search
- indexes over 100k selected Web pages that specialize in medical topics. This improves the the chances of finding relevant medical information. The search techniques are a bit cumbersome though.

By a process of selection, evaluation and description we are continuously updating our collection." You can search by keyword or MESH Headings. The abstracts are well written.
- Google
- is our current favorite Web search engine. It has few options so it's easy to use. All words are ANDed with no truncation of root words. Users can do a pharse search by using quotation marks. Google has very effective algorithms that increase the chances of retrieving relevant Web sites. Over 1 billion Web pages have been indexed. The Link: URL feature allows a user to retrieve all pages that have cited that URL. It's very hany for seeing which pages have links to your pages
