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.
Image Caption: APA Title Page
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.

If your instructor has specific requirements for the format of your research paper, check them before preparing your final draft. When you submit your paper, be sure to keep a secure copy.
The most common formatting is presented in the sections below:
Except for the running head (see below), leave margins of one inch at the top and bottom and on both sides of the text. If you plan to submit a printout on paper larger than 8½ by 11 inches, do not print the text in an area greater than 6½ by 9 inches.
Always choose an easily readable typeface (e.g., Times New Roman) in which the regular type style contrasts clearly with the italic, and set it to a standard size (e.g., 12 points). Do not justify the lines of text at the right margin; turn off any automatic hyphenation feature in your writing program. Double-space the entire research paper, including quotations, notes, and the list of works cited. Indent the first line of a paragraph half an inch from the left margin. Indent set-off quotations half an inch as well (for examples, see 76–80 in the MLA Handbook). Leave one space after a period or other concluding punctuation mark, unless your instructor prefers two spaces.
Heading and Title
Beginning one inch from the top of the first page and flush with the left margin, type your name, your instructor’s name, the course number, and the date on separate lines, double-spacing the lines. On a new, double-spaced line, center the title (fig. 1). Do not italicize or underline your title, put it in quotation marks or boldface, or type it in all capital letters. Follow the rules for capitalization in the MLA Handbook (67–68), and italicize only the words that you would italicize in the text.
Do not use a period after your title or after any heading in the paper (e.g., Works Cited). Begin your text on a new, double-spaced line after the title, indenting the first line of the paragraph half an inch from the left margin.
A research paper does not normally need a title page, but if the paper is a group project, create a title page and list all the authors on it instead of in the header on page 1 of your essay. If your teacher requires a title page in lieu of or in addition to the header, format it according to the instructions you are given.
Running Head with Page Numbers
Number all pages consecutively throughout the research paper in the upper right-hand corner, half an inch from the top and flush with the right margin. Type your last name, followed by a space, before the page number (fig. 2). Do not use the abbreviation p. before the page number or add a period, a hyphen, or any other mark or symbol. Your writing program will probably allow you to create a running head of this kind that appears automatically on every page. Some teachers prefer that no running head appear on the first page. Follow your teacher’s preference.
Placement of the List of Works Cited
The list of works cited appears at the end of the paper, after any endnotes. Begin the list on a new page. The list contains the same running head as the main text. The page numbering in the running head continues uninterrupted throughout. For example, if the text of your research paper (including any endnotes) ends on page 10, the works-cited list begins on page 11. Center the title, Works Cited, an inch from the top of the page (fig. 3). (If the list contains only one entry, make the heading Work Cited.) Double-space between the title and the first entry. Begin each entry flush with the left margin; if an entry runs more than one line, indent the subsequent line or lines half an inch from the left margin. This format is sometimes called hanging indention, and you can set your writing program to create it automatically for a group of paragraphs. Hanging indention makes alphabetical lists easier to use. Double-space the entire list. Continue it on as many pages as necessary.
Tables and Illustrations
Place tables and illustrations as close as possible to the parts of the text to which they relate. A table is usually labeled Table, given an arabic numeral, and titled. Type both label and title flush left on separate lines above the table, and capitalize them as titles (do not use all capital letters). Give the source of the table and any notes immediately below the table in a caption. To avoid confusion between notes to the text and notes to the table, designate notes to the table with lowercase letters rather than with numerals. Double-space throughout; use dividing lines as needed (fig. 4).
Any other type of illustrative visual material—for example, a photograph, map, line drawing, graph, or chart—should be labeled Figure (usually abbreviated Fig.), assigned an arabic numeral, and given a caption: “Fig. 1. Mary Cassatt, Mother and Child, Wichita Art Museum.” A label and caption ordinarily appear directly below the illustration and have the same one-inch margins as the text of the paper (fig. 5). If the caption of a table or illustration provides complete information about the source and the source is not cited in the text, no entry for the source in the works-cited list is necessary.
Musical illustrations are labeled Example (usually abbreviated Ex.), assigned an arabic numeral, and given a caption: “Ex. 1. Pyotr Ilich Tchaikovsky, Symphony no. 6 in B, opus 74 (Pathétique), finale.” A label and caption ordinarily appear directly below the example and have the same one-inch margins as the text of the paper (fig. 6).
Paper and Printing
If you print your paper, use only white, 8½-by-11-inch paper of good quality. If you lack 8½-by-11-inch paper, choose the closest size available. Use a high-quality printer. Some instructors prefer papers printed on a single side because they’re easier to read, but others allow printing on both sides as a means of conserving paper; follow your instructor’s preference.
Corrections and Insertions on Printouts
Proofread and correct your research paper carefully before submitting it. If you are checking a printout and find a mistake, reopen the document, make the appropriate revisions, and reprint the corrected page or pages. Be sure to save the changed file. Spelling checkers and usage checkers are helpful when used with caution. They do not find all errors and sometimes label correct material as erroneous. If your instructor permits corrections on the printout, write them neatly and legibly in ink directly above the lines involved, using carets (⁁) to indicate where they go. Do not use the margins or write a change below the line it affects. If corrections on any page are numerous or substantial, revise your document and reprint the page.
Binding a Printed Paper
Pages of a printed research paper may get misplaced or lost if they are left unattached or merely folded down at a corner. Although a plastic folder or some other kind of binder may seem an attractive finishing touch, most instructors find such devices a nuisance in reading and commenting on students’ work. Many prefer that a paper be secured with a simple paper or binder clip, which can be easily removed and restored. Others prefer the use of staples.
There are at present no commonly accepted standards for the electronic submission of research papers. If you are asked to submit your paper electronically, obtain from your teacher guidelines for formatting, mode of submission (e.g., by e-mail, on a Web site), and so forth and follow them closely.
