Look at Web sites with these questions in mind. The group or organization hosting the Web site should be clearly identified on the home page. Credible hosts include government agencies, medical schools, medical libraries, hospitals, universities, and professional associations.
Some sites have corporate sponsors.
Corporate sites may have good information, but probably will not include information about competing products and therapies. Consumer sites have less technical language. Look for the date of publication on an online publication or information sheet. A reputable Web site should make it easy for you to contact them with questions about content. If the site uses a complex layout or requires special software or a particular Web browser, you may want to go to a simpler, better-organized site.
