Record the name of the author if given. Copy the title of the article as well. Look at the search results listing for the article. Write down the publication in which it appeared, the date it originally appeared, the volume and issue if applicable and the page within the issue on which it appeared.
Determine in what type of publication the article appeared. Search for more details on the publication if you are unclear whether it is a scholarly journal, a newspaper, a magazine or a government publication.
Format the information that you recorded according to the citation style guide for your discipline. Consult your professor or the publisher if you are uncertain which format to follow. For example, the citation for a journal article from LexisNexis in MLA format would look like "Kay, Dennis. "Wyatt and Chaucer: 'They Flee From Me' Revisited." Huntington Library Quarterly 47.3 (1984): 211 -- 225. LexisNexis. Web. 23 May 2011."
Cite the article as you would a print article if using APA format. Provide information on the database (LexisNexis) only if the article cannot be found elsewhere. For example, the same article in APA looks like "Kay, Dennis. (1984). Wyatt and Chaucer: "They Flee From Me" Revisited. Huntington Library Quarterly 47(3), 211 -- 225." Include the digital object identifier (DOI) at the end of the citation when available.
