Finding Web Pages about Health

Three ways to start

There's all kinds of health information available on the web. There is also a great deal of misinformation out there, so it's important to evaluate web pages carefully.

Top level domains

An important part of each URL is the top level domain, which you'll find at the end of the URL for a basic home page, or just before the first single slash. For instance .gov is top level domain in these URLs:
       http://www.cdc.gov
       http://www.cdc.gov/cancer/skin/
The top level domain usually tells you something about who owns the webpage:

Wikipedia

Wikipedia is an unreliable and unstable source of information. The edit this page tab allows anybody and everybody to remove or add whatever they want to Wikipedia articles. For most articles, clicking on the history tab will reveal that the text is being changed many times every month, and sometimes many times every day. Because it is so unstable, most CCSF instructors will NOT accept Wikipedia articles as sources for your research. However, if you really know nothing about a topic, parts of a Wikipedia article can be used to help you start on your research. The first paragraph usually gives many technical terms that might make good search words. The list of topics given in the Contents box can help shape your research. The bottom of the article may have External links to reliable sources. If you start your research in Wikipedia, always confirm your facts with other, reliable web sites before you use them for a research project or to make decisions about your health.
