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).

General APA Guidelines
Your essay should be typed and double-spaced on standard-sized paper (8.5" x 11"), with 1" margins on all sides. You should use a clear font that is highly readable. APA recommends using 12 pt. Times New Roman font.
Include a page header (also known as the "running head") at the top of every page. To create a page header/running head, insert page numbers flush right. Then type "TITLE OF YOUR PAPER" in the header flush left using all capital letters. The running head is a shortened version of your paper's title and cannot exceed 50 characters including spacing and punctuation.
Major Paper Sections
Your essay should include four major sections: the Title Page, Abstract, Main Body, and References.
The title page should contain the title of the paper, the author's name, and the institutional affiliation. Include the page header (described above) flush left with the page number flush right at the top of the page. Please note that on the title page, your page header/running head should look like this:
Running head: TITLE OF YOUR PAPER
Pages after the title page should have a running head that looks like this:
TITLE OF YOUR PAPER
After consulting with publication specialists at the APA, OWL staff learned that the APA 6th edition, first printing sample papers have incorrect examples of running heads on pages after the title page. This link will take you to the APA site where you can find a complete list of all the errors in the APA's 6th edition style guide.
Type your title in upper and lowercase letters centered in the upper half of the page. APA recommends that your title be no more than 12 words in length and that it should not contain abbreviations or words that serve no purpose. Your title may take up one or two lines. All text on the title page, and throughout your paper, should be double-spaced.
Beneath the title, type the author's name: first name, middle initial(s), and last name. Do not use titles (Dr.) or degrees (PhD).
Beneath the author's name, type the institutional affiliation, which should indicate the location where the author(s) conducted the research.

Begin a new page. Your abstract page should already include the page header (described above). On the first line of the abstract page, center the word “Abstract” (no bold, formatting, italics, underlining, or quotation marks).
Beginning with the next line, write a concise summary of the key points of your research. (Do not indent.) Your abstract should contain at least your research topic, research questions, participants, methods, results, data analysis, and conclusions. You may also include possible implications of your research and future work you see connected with your findings. Your abstract should be a single paragraph, double-spaced. Your abstract should be between 150 and 250 words.
You may also want to list keywords from your paper in your abstract. To do this, indent as you would if you were starting a new paragraph, type Keywords: (italicized), and then list your keywords. Listing your keywords will help researchers find your work in databases.

MLA Format in Detail
This page contains general guidelines on how to properly format the headings on a paper using MLA format.
Without a Cover Page:
This is the most common way to begin an MLA essay because MLA does not require a cover page. Some instructors, however, may require one (see instructions and example below).
1. The Opening Page:
On the opening page or the first page, a comprehensive identification (sometimes referred to as the main heading) and essay title should appear. The identification includes the following information:
- Student/Author Name
- Instructor’s Name
- Class Name/Information
- Your Paper’s Due Date
- Font: choose an easy to read font such as Times New Roman
- Font Size: set the font size to be 12 throughout the paper, including the paper’s title. Never set the font size larger than 12.
- Margins: 1-inch for top/bottom/right/left throughout the paper
- Double-space: double-space throughout he paper. Don’t add extra spaces (besides the already used double-spacing) between headings, title and/ paragraphs. Important Note: In the newest Microsoft Word settings, adding extra spaces between paragraphs is a default setting and must be disabled by the writer; otherwise, extra spaces will be automatically created.
Sample of the opening page:
With a Cover Page:
The Modern Language Association (MLA) does not require a cover page, but some instructors may require it. In certain situations or assignments, a paper with a cover page can look more professional.
Instructors who require the paper to have a cover page usually provide specific instructions on what should be included. Here is the general MLA Format cover page. This page should include your school or university’s name (i.e. Aims Community College), a paper title, author name, class name, professor name and paper due date.
Here is how to format an MLA cover page:
- This page is double-spaced and the letters are centered.
- Type the name of your university or college.
- Skip to about one-third of the page and type the research paper title, including subtitle if there is one.
- Skip several lines and type student/author name, course name and number, instructor name and paper due date.

Alternate First Page:
If an instructor requires a cover page, the identification heading on the first page should be omitted. Below is an example of the first page if a cover page is used. Last name and page number should appear on all pages, and the title should appear at the top of the first page only.
Sample MLA Format First Page with Cover Page
2. The Inner Pages:
For the pages that follow the first page, set the heading like this: instead of the whole heading, use the header feature in the word-processing program to include author last name and page number.
Inner Page Example:
Example of the heading for inner pages.
3. The Works Cited Page:
Every research paper must include a works cited page(s).
- The works cited list is placed at the end of the paper, beginning on a new page.
- The header for the works cited page(s) should be similar to the header for the inner pages, which includes author name and the page number at the top.
- Enter the title as “Works Cited” and place this title 1-inch from the top of the page, see more details in the example illustration below.
