If you would like to cite more than one source within the same in-text citation, simply record the in-text citations as normal and separate them with a semi-colon.
(Smith 42; Bennett 71).
(It Takes Two; Brock 43).
Note: The sources within the in-text citation do not need to be in alphabetical order for MLA style.
In MLA, in-text citations are inserted in the body of your research paper to briefly document the source of your information. Brief in-text citations point the reader to more complete information in the works cited list at the end of the paper.
Note: The period goes outside the brackets, at the end of your in-text citation.
When you quote directly from a source, enclose the quoted section in quotation marks. Add an in-text citation at the end of the quote with the author name and page number:
Mother-infant attachment has been a leading topic of developmental research since John Bowlby found that "children raised in institutions were deficient in emotional and personality development" (Hunt 358).
No Page Numbers
When you quote from electronic sources that do not provide page numbers (like Web pages), cite the author name only.
"Three phases of the separation response: protest, despair, and detachment" (Garelli).
If you refer to the author's name in a sentence you do not have to include the name again as part of your in-text citation, instead include the page number (if there is one) at the end of the quotation or paraphrased section. For example:
Hunt explains that mother-infant attachment has been a leading topic of developmental research since John Bowlby found that "children raised in institutions were deficient in emotional and personality development" (358).
If you're using information from a single source more than once in succession (i.e., no other sources referred to in between), you can use a simplified in-text citation.
Cell biology is an area of science that focuses on the structure and function of cells (Smith 15). It revolves around the idea that the cell is a "fundamental unit of life" (17). Many important scientists have contributed to the evolution of cell biology. Mattias Jakob Schleiden and Theodor Schwann, for example, were scientists who formulated cell theory in 1838 (20).
Note: If using this simplified in-text citation creates ambiguity regarding the source being referred to, use the full in-text citation format.
