|The American Psychological Association (APA) citation format is widely used in disciplines within the social and behavioral sciences, such as Psychology, Sociology, Economics, Criminology, Business and Nursing. It sets out rules and standards for the preparation of manuscripts for publication, the writing of bibliography of references and in-text citations, the avoidance of plagiarism and more.
Whether you are a professional writer, student, researcher or professional in a field within these disciplines, the APA style guide is a valuable tool for writing scientific papers, laboratory reports, and papers.
Most commonly occurs for wiki entries, dictionary entries and unattributed website content.
Date = Year of Publication (usually found on the copyright page of books and first page of journal articles).
Include the year and exact date of the publication (month or month and day). Weeklies like Nature, Science and The Lancet - use month, day, and year.
Many websites or webpages do not include publication dates. If no date of publication is provided, use the letters n.d. (which stand for “no date”). The copyright date on the website itself should not be used as the publication date for particular content on that site.
Journal Articles, Journals, Book Chapters, Books
General rule: Italicize the parent element. Journal article: Article (child element) is contained within journal (parent element), so article title is not italicized but the journal title is. Book chapters, follow the same pattern.
Use direct quotations selectively to be effective.
You would quote directly:
Include author, year of publication and page number.
According to Fossel (2014), “Whenever we try to control something that we cannot comprehend, such as nature, there will be no end of trouble” (p. 33).
Fossel (2014) found that “there will be no end of trouble” (p. 33), whenever we try to subdue nature.
He stated, “Whenever we try to control something that we cannot comprehend, such as nature, there will be no end of trouble” (Fossel, 2014, p. 33), and then offers an explanation as to why.
Fossel’s (2014) study found the following:
Land that’s been conventionally farmed cannot be certified organic for three years. During that time, it’s considered to be in transition. But while chemical detoxification can take three years, that may be just the beginning in terms of fertility. It’s impossible to say with any certainty because of all the variables. (p. 35)
Use square brackets to insert changes, additions, or explanations into a quotation. However, when you change capitalization at the beginning of a quotation, punctuation at the end of a quotation, or double quotation marks to single within a quotation, square brackets are not required.
Commenting on the writing process, Stewart, Bullock, and Allen (2006) said, “We must recognize that their [professional writers’] method is almost always to write out a rough draft, let it sit for a while, and then submit it to a process of revision and fine tuning” (p. 64).
Use ellipsis points (three periods with a space before and after each period) if you omit part of the original text.
Qiao et al. (2018) pointed out that “small-scale farmers . . . mainly produced for themselves and only had a small portion of their production left for sale before organic farming was introduced” (p. 305).
Exception: Use four periods (literally a period and three ellipsis points) if you omit words between two sentences.
Qiao et al. (2018) noted that “while training is important . . . . village or township leaders as well as governmental extension workers played the most important role in the learning and adaptation of new agricultural techniques” (p. 304).
When citing a work by two authors, name both authors in the signal phrase or in the parentheses each time you cite the work. Use the word “and” between the authors’ names within the text and use the ampersand in the parentheses.
Research by Huang and Lee (2014) supports …
(Huang & Lee, 2014)
When citing a work by three to five authors, list all the authors in the signal phrase or in parentheses the first time you cite the source. Use the word "and" between the authors' names within the text and use the ampersand in the parentheses.
(Peng, Huang, Chen, Lin, & Wang, 2017)
In subsequent citations, only use the first author's last name followed by "et al." in the signal phrase or in parentheses.
(Peng et al., 2017)
Six or More Authors: Use the first author's name followed by et al. in the signal phrase or in parentheses.
Jones et al. (2001) argued...
(Jones et al., 2001)
If the work does not have an author, cite the source by its title in the signal phrase or use the first word or two in the parentheses. Titles of books and reports are italicized or underlined; titles of articles, chapters, and web pages are in quotation marks.
Opting to go green as a lifestyle choice can become a profitable business ("Green essentials," 2012).
If the author is an organization or a government agency, mention the organization in the signal phrase or in the parenthetical citation the first time you cite the source. According to the American Psychological Association (2000),... If the organization has a well-known abbreviation, include the abbreviation in brackets the first time the source is cited and then use only the abbreviation in later citations.
First citation: (World Health Organization [WHO], 2013)
Second citation: (WHO, 2013)
If you use a source that was cited in another source, name the original source in your signal phrase. List the secondary source in your reference list and include the secondary source in the parentheses.
For interviews, letters, e-mails, and other person-to-person communication between you and someone, cite the communicator's name, the fact that it was personal communication, and the date of the communication. Do NOT include personal communication in the reference list.
(L. Tan, personal communication, January 4, 2018).
M. K. Lim said that for the freshest produce, we should buy local (personal communication, November 13, 2017).
If possible, cite an electronic document the same as any other document by using the author-date style.
Kenneth (2000) explained...
Two or More Works in the Same Parentheses
When your parenthetical citation includes two or more works, order them the same way they appear in the reference list (viz., alphabetically), separated by a semi-colon.
(Miller, 2008; O’Connell, 2015)
If no author or date is given, use the title in your signal phrase or the first word or two of the title in the parentheses and use the abbreviation "n.d." (for "no date").
Another study of students and research decisions discovered that students succeeded with tutoring ("Tutoring and Improving," n.d.).
When an electronic source lacks page numbers, you should try to include information that will help readers find the passage being cited. When an electronic document has numbered paragraphs, use the abbreviation "para." followed by the paragraph number.
If the paragraphs are not numbered and the document includes headings, provide the appropriate heading and specify the paragraph under that heading. Note that in some electronic sources, like Web pages, people can use the Find function in their browser to locate any passages you cite.
The period of Japanese occupation imposed strict censorship and obstacles to the growth of the Korean film industry, culminating in a complete ban of Korean-speaking films in 1942 (Kim, 2017, para. 2).
Note: Never use the page numbers of Web pages you print out; different computers print Web pages with different pagination.
Your essay should be typed, double-spaced on standard-sized paper (8.5" x 11") with 1" margins on all sides. APA recommends using 12 pt. Times New Roman font.
APA 7 provides slightly different directions for formatting the title pages of
1) Professional papers for example papers that are written for submission to a scholarly publication.
2) Student papers for example papers that are written for submission for a student assignment to a specific module.
For a Professional paper
The title page should contain the title of the paper, the author's name, and the institutional affiliation. A professional paper should also include the author note. Include the page header, flush left with the page number flush right at the top of the page.
For a Student paper
A student paper should also contain the title of the paper, the author's name but include the course number and name, instructor name, and assignment due date.

Always start your reference on a new page.
Make sure to double space the list.
Reference list entries should be alphabetized by the last name of the first author of each work.
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 twenty authors, list the first twenty authors and then use ellipses after the sixth author's name. After the ellipses, list the last author's name of the work.
Capitalize all major words in journal titles. When referring to books, chapters, articles, or Web pages, 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.
