The vast amount of information on the World Wide Web is created and published by many different types of providers, including businesses, organizations, governments, and individuals. Unlike books and journals, most of this information is unfiltered, i.e. not subject to editing or peer review by experts. So it's important to evaluate the Web sources you use. Any source you find was written for specific reasons that may or may not be useful for your purposes. This checklist offers a series of evaluation questions you can use to assess how a given Web document fits your needs.
