APA Style - 7th edition: Specific Rules for Authors & Titles

There are certain things to keep in mind when writing the author's name according to APA style. Authors may be individual people, multiple people, groups (institutions or organizations), or a combination of people and groups. 

• You must include all the authors up to 20 for individual items. For example, if you are using an article that has 19 authors you must list them all out on your reference page. 
• Use initials for the first and middle names of authors. Use one space between initials.
• All names are inverted (last name, first initial).
• Do not hyphenate a name unless it is hyphenated on the item.
• Separate the author's names with a comma and use the ampersand symbol "&"  before the last author listed.
• Spell out the name of any organization that is listed as an author.
• If there is no author listed, the item title moves in front of the publication date and is used.

An item that you use may have an editor instead of an author or in the case of audiovisual materials a writer or director.

• For editors follow the same rules above and put the abbreviation (Ed.) or (Eds.) behind the name(s). 
• For audiovisual materials follow the same rules as above and put the specialized role (Writer) (Director) behind the name. 

Examples:

Zhang, Y. H.  (one author)

Arnec, A., & Lavbic, D. (two authors)​

Kent State University (organization as author)

Barr, M. J. (Ed.). (1 editor)

Powell, R. R., & Westbrook, L. (Eds.). (2 editors)

here are certain things to keep in mind when writing a title according to APA style.

• Book titles are italicized and written using sentence case (only the first word of a title, subtitle, or proper noun are capitalized).
• Book chapter titles are written using sentence case and are not italicized.
• Journal titles are italicized and written using title case (all the important words are capitalized).
• Article titles are written using sentence case and are not italicized.
• Webpages and websites are italicized and written using sentence case.

Examples:

Publication manual of the American Psychological Association (book title, American Psychological Association is a proper noun so it is capitalized)

Student perspective of plagiarism (book chapter title)

Internet plagiarism in higher education: Tendencies, trigging factors and reasons among teacher candidates (article title, Tendencies is the first word of a sub-title so it is capitalized)

Assessment & Evaluation in Higher Education (journal title)
