The Online Writing Lab (OWL) created by Purdue University provides detailed information on MLA formatting.
In-Text Citation Guidelines
Citing a reference within the text of your paper is called an "in-text citation," which "should direct the reader unambiguously to the entry in your works cited list for the source—and, if possible, to a passage in the source—while creating the least possible interruption in your text" (MLA 54).
You must cite your references both in your reference list and in the text of your paper where that source is used.
An in-text citation needs to contain enough information to point your reader to the full citation in the works cited list. You also need to include a page number if pointing to a specific piece of information from your source.
You will present the information from your source in your paper as either a direct quotation or paraphrased (re-written in your own words). You do not need to cite common knowledge, that is, information that most people know or established facts.
If the author is clear (i.e. is stated in the text), their name is not included in the in-text citation.
When you are citing multiple works by the same author, include an abbreviation of the title after the author. Some works have standardized abbreviations, including Shakespeare and the Bible.
Always provide in-text citations for the following:
Quotations and paraphrases of other sources.
Facts and figures that are not common knowledge.
Tables and images, even if they are open source.
In-Text Citation Examples
Include the last name of the author and the page number.
