This list of Internet resources is selective and limited to those sites the Library staff has found useful. Inclusion of a site does not imply the Library or Penn State Milton S.

Evaluating Health Information on the Internet
Unlike information found in medical textbooks, which has been evaluated and edited by professionals, the information on the Internet is unfiltered. It is up to the user to evaluate and judge how good the information really is. When looking for health information it is particularly important to think about the information critically and examine the Web site carefully. Listed below are some questions and tips to think about when searching for good health information on the Internet.
What type of site is it? Is it a government site, educational or commercial? Look at the web address for the extension. The most common are .gov for government, .edu for educational, .com for commercial and .org for organizational.
Who is sponsoring the site? A good Web site will make sponsorship information clear. There should also be an address (besides an e-mail address) or a phone number to contact for more information.
What are the credentials of the sponsor or author of the material on site? If it is an organization or association, is it nationally recognized or is it a local group? Also, are the author's qualifications relevant to the topic being discussed? For example, someone with a Ph.D. in psychology should not necessarily be accepted as an expert on nutrition.
What is the purpose of the site? Is it a public service or is it trying to sell something? If there is advertising on a page, something that is more and more common even with non-commercial sites, it should be clearly separated from the informational content. Also, it is easy to disguise promotional material as "patient education" on web sites. If a product or treatment is given a good review on one site, try to find other sites that also approve of it.
How current is the information? A good site will list when a page was first established and when it was last up-dated. If there are links to other sites, are they up-to-date?
How accurate is the information? This can be hard to determine if you're not familiar with a topic but there are some things to look for. For example, is the information free of spelling errors and typos? Mistakes of these kind can indicate a lack of quality control. Are the sources of factual information listed? For instance, if a document states, "recent studies indicate...", are the sources for the study listed so they can be verified? If a topic is controversial, is the information presented in a balanced way? There are many controversies in regard to treatment options; however, a good site will present the pros and cons of a particular option. Be cautious with sites that claim "miracle cures" or make conspiracy claims.
Evaluate each site separately. Links can often lead from a good site to ones of lesser quality.
Look for awards or certificates that a site has received. For example, the HON Code logo is displayed by sites that have agreed to abide by eight principals set by the Health on the Net Foundation. These principles set standards for accuracy, bias, sponsorship and confidentiality. When using a directory or search engine that rates sites, read the page that discusses what criteria are used to determine a site's rating.
The Internet is a wonderful source of information and, when used carefully, can be very helpful in answering health-related questions. But the information found on the Internet should never be used as a substitute for consulting with a health professional. And, whenever using the Internet, keep in mind the caveat, "It is so easy to post information on the Internet that almost any idiot can do it, and almost every idiot has."
