Even if you have a name, the credentials of the person or organization may not be listed, and you will need to do additional research. Remember though that the domain is not always an indicator of authority. A university may allow faculty and students to place their own Web sites on its server. Faculty pages, if they relate to the person's area of expertise, should be authoritative. Student pages, on the other hand, may not be.
Some Web sites provide information on the author or organization.
These may be at the top or bottom or along the side of the home page. Remember that a single author or organization may not be responsible for all of the information on a Web site. Take a look at this Web page reporting a study on the reactions of cats to bearded men . Most are affiliated with well-known universities, but no information is given about their positions at these universities. Now read the page.
