APA (American Psychological Association) style is most commonly used to cite sources within the social sciences. This resource, revised according to the 6th edition, second printing of the APA manual, offers examples for the general format of APA research papers, in-text citations, endnotes/footnotes, and the reference page. For more information, please consult the Publication Manual of the American Psychological Association, (6th ed., 2nd printing).

Your reference list should appear at the end of your paper. It provides the information necessary for a reader to locate and retrieve any source you cite in the body of the paper. Each source you cite in the paper must appear in your reference list; likewise, each entry in the reference list must be cited in your text.
Your references should begin on a new page separate from the text of the essay; label this page "References" centered at the top of the page (do NOT bold, underline, or use quotation marks for the title). All text should be double-spaced just like the rest of your essay.
- All lines after the first line of each entry in your reference list should be indented one-half inch from the left margin. This is called hanging indentation.
- Authors' names are inverted (last name first); give the last name and initials for all authors of a particular work for up to and including seven authors. If the work has more than seven authors, list the first six authors and then use ellipses after the sixth author's name. After the ellipses, list the last author's name of the work.
- Reference list entries should be alphabetized by the last name of the first author of each work.
- For multiple articles by the same author, or authors listed in the same order, list the entries in chronological order, from earliest to most recent.
- Present the journal title in full.
- Maintain the punctuation and capitalization that is used by the journal in its title.
- For example: ReCALL not RECALL or Knowledge Management Research & Practice not Knowledge Management Research and Practice.
- Capitalize all major words in journal titles.
- When referring to books, chapters, articles, or webpages, capitalize only the first letter of the first word of a title and subtitle, the first word after a colon or a dash in the title, and proper nouns.
- Italicize titles of longer works such as books and journals.
- Do not italicize, underline, or put quotes around the titles of shorter works such as journal articles or essays in edited collections.
- Please note: While the APA manual provides many examples of how to cite common types of sources, it does not provide rules on how to cite all types of sources. Therefore, if you have a source that APA does not include, APA suggests that you find the example that is most similar to your source and use that format. For more information, see page 193 of the Publication Manual of the American Psychological Association, 6th ed., 2nd printing.
MLA Works Cited Page: Basic Format
MLA (Modern Language Association) style is most commonly used to write papers and cite sources within the liberal arts and humanities. This resource, updated to reflect the MLA Handbook (8th ed.), offers examples for the general format of MLA research papers, in-text citations, endnotes/footnotes, and the Works Cited page.

According to MLA style, you must have a Works Cited page at the end of your research paper. All entries in the Works Cited page must correspond to the works cited in your main text.
- Begin your Works Cited page on a separate page at the end of your research paper. It should have the same one-inch margins and last name, page number header as the rest of your paper.
- Label the page Works Cited (do not italicize the words Works Cited or put them in quotation marks) and center the words Works Cited at the top of the page.
- Double space all citations, but do not skip spaces between entries.
- Indent the second and subsequent lines of citations by 0.5 inches to create a hanging indent.
- List page numbers of sources efficiently, when needed. If you refer to a journal article that appeared on pages 225 through 250, list the page numbers on your Works Cited page as 225-250. Note that MLA style uses a hyphen in a span of pages.
- If you're citing an article or a publication that was originally issued in print form but that you retrieved from an online database, you should type the online database name in italics. You do not need to provide subscription information in addition to the database name.
Additional basic rules new to MLA 2016
New to MLA 2016:
- For online sources, you should include a location to show readers where you found the source. Many scholarly databases use a DOI (digital object identifier). Use a DOI in your citation if you can; otherwise use a URL. Delete “http://” from URLs. The DOI or URL is usually the last element in a citation and should be followed by a period.
- All works cited entries end with a period.
Capitalization and punctuation
- Capitalize each word in the titles of articles, books, etc, but do not capitalize articles (the, an), prepositions, or conjunctions unless one is the first word of the title or subtitle: Gone with the Wind, The Art of War, There Is Nothing Left to Lose.
- Use italics (instead of underlining) for titles of larger works (books, magazines) and quotation marks for titles of shorter works (poems, articles)
Listing author names
Entries are listed alphabetically by the author's last name (or, for entire edited collections, editor names). Author names are written last name first; middle names or middle initials follow the first name:
Levy, David M.
Wallace, David Foster
Do not list titles (Dr., Sir, Saint, etc.) or degrees (PhD, MA, DDS, etc.) with names. A book listing an author named "John Bigbrain, PhD" appears simply as "Bigbrain, John"; do, however, include suffixes like "Jr." or "II." Putting it all together, a work by Dr. Martin Luther King, Jr. would be cited as "King, Martin Luther, Jr." Here the suffix following the first or middle name and a comma.
More than one work by an author
If you have cited more than one work by a particular author, order the entries alphabetically by title, and use three hyphens in place of the author's name for every entry after the first:
Burke, Kenneth. A Grammar of Motives. [...]
---. A Rhetoric of Motives. [...]
When an author or collection editor appears both as the sole author of a text and as the first author of a group, list solo-author entries first:
Heller, Steven, ed. The Education of an E-Designer.
Heller, Steven, and Karen Pomeroy. Design Literacy: Understanding Graphic Design.
Work with no known author
Alphabetize works with no known author by their title; use a shortened version of the title in the parenthetical citations in your paper. In this case, Boring Postcards USA has no known author:
Baudrillard, Jean. Simulacra and Simulations. [...]
Boring Postcards USA. [...]
Burke, Kenneth. A Rhetoric of Motives. [...]
