APA style is published by the American Psychological Association. It is most commonly used in science courses.
Generally, APA citations follow the following format:
Contributors. (Date). Title (Secondary Contributors). Publication Information.
Contributor Information and Titles
The main contributors of the source, normally the author, are placed before the title. If there is more than one author, arrange the authors in the same order found in the source. Use the first and middle name initials and the entire last name. Inverse all names before the title.
Smith, J. K. (Date). Title.
Smith, J. K., & Sampson, T. (Date). Title.
Smith, J. K., Sampson, T., & Hubbard, A. J. (Date). Title.
Eight or more:
Smith, J. K., Sampson, T., Hubbard, A. J., Anderson, J., Thompson, T., Silva, P.,…Bhatia, N. (Date). Title.
Other contributor types
Sometimes the main contributor is not an author, but another contributor type, such as an editor for a book or conductor for a musical piece. In this instance, follow the contributor by an abbreviation of the contributor type (i.e. Ed. or Cond.). If plural, then change the abbreviation accordingly.
Smith, J. K. (Ed.). (Date). Title.
Smith, J. K., & Sampson, T. (Eds.). (Date). Title.
Smith, J. K. (Cond). (Date). Title.
Many sources have secondary contributors – individuals who added to the work outside the main contributors. This can include editors and translators for books, and producers and screenplay writers for movies. Place secondary contributors after the title in parenthesis. List them in first initial, middle initial, last name format and follow this by the contributor type abbreviation. Separate different contributor types by semicolons.
Smith, J. (Date). Title (B. McCoy, Ed.).
Smith, J. (Date). Title (B. McCoy & T. Thomas, Eds.).
One editor, two translators:
Smith, J. (Date). Title (B. McCoy, Ed.; B. Smith & P. R. Silva, Trans.).
Corporate or group authors
Some sources may have corporate or group authors. Write these organizations where you would write the author. If the organization is also the publisher of the source, write “Author” instead of repeating the publisher name.
American Psychological Association. (Date). Title.
Illinois Department of Industrial Relations. (Date). Title.
No contributor information
Sometimes you will come across sources with no contributor information. In this instance, do not write the date first. Instead, write the name of the title and then the date, then followed by the remaining appropriate bibliographic data.
Webster’s dictionary. (1995). Springfield, MA: Merriam-Webster.
Some sources are foundwithin other sources, such as a chapter in a book or an article in a periodical. These rules apply both to the contributors of the chapter and book or to the article.
Chapter author and translator, and book editor and translator:
Smith, J. (Date). Chapter title (B. McCoy, Trans.). In R. Engels (Ed.) & S. Simpson (Trans.), Title.
Author and translator of an article:
Smith, J. (Date). Article title (B. McCoy, Trans.). Periodical Title.
Note: When citing a chapter, the book contributors are preceded by “In.”
Title Rules – Capitalization and Italics
Article titles and works within larger works, such as chapters and webpages, as well as informally published material are not italicized. Main titles, such as those for books and journals, are italicized. Generally, capitalize the first letter of the first word of the title or any subtitles, and the first letter of any proper nouns. For titles of periodicals, such as journals and newspapers, capitalize every principal word.
After the contributor information and title comes the publication information. Below are different publication information templates.
Last, F. M. (Date Published). Book Title. City, State: Publisher.
Last, F. M. (Date Published). Article title. Journal Title, Volume(Issue), Page(s).
Last, F. M. (Date Published). Article title. Magazine Title, Volume, Page(s).
Last, F. M. (Date Published). Webpage Title. Retrieved from URL.
Last, F. M. (Date Published). Article title. Newspaper Title, Page(s).
Include as much detail regarding the date as possible. See the below examples:
(2002, February 12), (2002, February), (2002, February-March), (2002).
Note: If there is no date, use “n.d” instead, which means “no date.”
For any information unavailable, exclude the datapoint, and adjust the punctuation accordingly. EasyBib will properly format your citation based on the information entered.
Note: Page numbers for chapters of books and newspapers are preceded by “p.” or “pp.” [plural], while those of magazines and journals are only written with numbers.
For less conventional source types, you can add descriptions about the source after the title in brackets immediately after the title. For example, you can add “[Brochure]” after the title of a brochure (separated by a space) to clarify what type of source you are citing.
When citing non-periodical sources, advanced information such as the edition, series, and page information comes before the publication information and after the title grouped in the same parenthesis. See the fictional example below:
