Find Background Information - Entries and embedded links can be used to generate ideas and learn the terminology associated with your topic.
Generate Search Terms - Take a look at the embedded links, bolded words, or table of contents. They can help generate search terms to use for searching in library databases.
Look at the Bibliography - The bottom of the page should list the sources used to compile the entry. They can point you to other resources (sometimes scholarly) on the topic.
Cite to Wikipedia - In academic research, you usually never cite to an encyclopedia or other sources of background information.
Believe Everything - Because the content is user-created, anonymous, and does not have a mandatory review process, there is no guarantee that the information is accurate and credible.
