Each citation style handles this situation a little bit differently! Here are specific examples of how it works in the three major citation styles:
Per the APA Manual (6th edition), p. 178:
For In-Text Citations:
Arrange two or more works by the same authors (in the same order) by year of publication. Place in-press citations last. Give the authors’ surnames once; for each subsequent work, give only the date.
Training materials are available (Department of Veterans Affairs, 2001, 2003)
Past research (Gogel, 1990, 2006, in press)
Identify works by the same author (or by the same two or more authors in the same author) with the same publication date by the suffixes a, b, c, and so forth, after the year; repeat the year. The suffixes are assigned in the reference list, where these kinds of references are ordered alphabetically by title (of the article, chapter or complete work).
Several studies (Derryberry & Reed, 2005a, 2005b, in press-a; Rothbart, 2003a, 2003b)
For additional examples and tips on citing multiple sources by the same author in APA Style, check out the APA Style Blog’s posts on How to Cite Multiple Works by the Same Author in a Compilation and How to Cite Articles with the Same Authors and Same Year.
In the Works Cited (Per the MLA Handbook (8th edition), p. 113: To cite two or more works by the same author, give the name in the first entry only. Thereafter, in place of the name, type three hyphens, followed by a period and the title. The three hyphens stand for exactly the same name as in the preceding entry. This sort of label does not affect the order in which the entries appear; works listed under the same name are alphabetized by title.
For in-text citations (Per the MLA Handbook (8th edition), p. 55: Including only the author name and page number in a parenthetical citation is insufficient if more than one work appears under that author's name in the work cited list. In that case, include a shortened version of the source's title.
(Haynes, Noah's Curse 84)
(Haynes, The Last Segregated Hour 57)
Works cited (don't forget to indent the second and subsequent lines):
Haynes, Stephen R. Noah's Curse: The Biblical Justification of American Slavery. Oxford University Press, 2007.
---. The Last Segregated Hour: The Memphis Kneel-Ins and the Campaign for Southern Church Desegregation. Oxford University Press, 2012.
For additional examples and tips on multiple sources by the same author in MLA Style, check out the MLA Style Center's "How do I distinguish works by an author that have the same title?"
Per the Chicago Manual of Style (17th edition):
Notes and Bibliography method (see section 14.68: The 3-em dash for one repeated name for caveats please refer to 14.67).
For successive entries [in a bibliography] by the same author, editor, translator, or compiler, a 3-em dash (followed by a period or comma, depending on the presence of an abbreviation such as ed.) replaces the name after the first appearance.
For example: (don't forget to indent the second and subsequent lines):
Judt, Tony. A Grand Illusion? An Essay on Europe. New York: Hill and Wang, 1996.
———. Reappraisals: Reflections on the Forgotten Twentieth Century. New Yrok: Penguin Press, 2008.
In a bibliography, titles by the same author are normally listed alphabetically.
Author-Date References (see section 15.18: Chronological order for repeated names in a reference list)
For successive entries by the same author(s), translator(s), editor(s), or compiler(s), a 3-em dash replaces the name(s) after the first appearance. The entries are arranged chronologically by year of publication in ascending order, not alphabetized by title. Undated works designated n.d. or forthcoming follow all dated works.
For example: (don't forget to indent the second and subsequent lines):
Schuman, Howard, and Jacqueline Scott. 1987. “Problems in the Use of Survey Questions to Measure Public Opinion.” Science 236:957-59.
———. 1989. “Generations and Collective Memories.” American Sociological Review 54:359-81.
Two or more works by the same author in the same year must be differentiated by the addition of a, b, and so forth (regardless of whether they were authored, edited, compiled or translated), and are listed alphabetically by title. Text citations consist of author and year plus letter.
Fogel, Robert William. 2004a. The Escape from Hunger and Premature Death, 1700-2100: Europe, America, and the Third World. New York: Cambridge University Press, 2004.

How to Format an Author’s Name in MLA 8
It’s vitally important to make sure you correctly cite the last name of the author(s) whose work you’re referencing. To correctly cite the author, always begin the citation with the author’s last name, a comma, and the rest of the name as it appears on the source. Place a period after the author’s name. Here are some examples for citing one or more authors:
How to Cite One Author:
King, Laurie R.
How to Cite Two Authors:
Place the authors in the order in which they appear on the source. Note that only the lead author’s name is listed last name first; all additional authors are listed by their first name, middle initial initial if applicable, and then last name:
Shields, David, and Caleb Powell.
How to Cite Three or More Authors:
List the author’s last name, first name, and then middle initial if applicable. Follow it with a comma, and then add et al. in place of the additional authors:
Beck, Isabel L., et al.
How to Cite Works by Individuals Other Than the Author:
In cases where the person responsible for creating a work is someone other than the author, such as an editor, producer, performer, or artist, always include the individual’s role after the name:
Kansaker, Tej Ratna, and Mark Turin, editors.
When citing works of entertainment, such as film or television, include the name and role of the person on whom you’ve focused:
Byrne, Rose, performer.
*Note: If you are writing about a film or television show that does not focus on an individual’s role, omit the author’s name and start the citation with the title.
How to Cite Translated Works:
When your focus is on the translated text rather than the original, treat the translator as the author. Include the name of the original creator after the title, preceded by the word By:
Rojas, Carlos, translator. The Four Books. By Yan Lianke.
How to Cite Using Pseudonyms in MLA 8:
Usernames and online handles are now acceptable to use as the author’s name.
How to Cite Corporate Authors in MLA 8:
If a corporation is the author of the text, include the full name of the corporation:
The New York City Department of Education.
How to Cite when There is No Author in MLA 8:
When no author is given in a text, omit this section and start the citation with the title.
