The primary purpose of an informational Web page is to provide factual information. Examples of materials found on informational pages include government research reports, census data, and information typically found in encyclopedias and other reference works. Information about a topic can be found on numerous different types of Web pages, so the Uniform Resource Locator address of an informational page may have any one of a variety of endings. When analyzing an informational Web page, the first step is to ask the general questions listed in the Checklist of Basic Elements. In addition, a user must also apply the checklist questions from the Informational Checklist to determine: the nature of the information provider; whether the information is likely to be reliable, authoritative, and trustworthy, and whether the information at the site is relevant to the user's information needs.
