APA 6 Style Guide
In-text citations are required when you use someone else's ideas, theories or research in your paper.
No authors: Use the title in place of author. Shorten title if needed. Use double quotation marks for title of an article, a chapter, or a web page. Use italics for title of a periodical, a book, a brochure or a report.

Three to five authors: Include all authors' last names the first time the citation is used. If you use the same citation again within the same paragraph, use only the first last name followed by 'et al'. If you used the citation again omit the year.

When quoting always provide author, year and specific page citation or paragraph number for nonpaginated material.
If the quotation is less than 40 words incorporate it into the text and enclose the quotation with quotation marks. Cite the source immediately after the close of the quotation marks.
If the authors are named in the text, they do not have to be used in the citation.

"A neurosis is characterized by anxiety," according to Kristen and Warb's (2012, p. 157) longitudinal study.
If the quotation is over 40 words, you must indent the entire quotation and start the quotation on a new line. No quotation marks are required. Cite the quoted source after the final punctuation mark.

APA style encourages the inclusion of page numbers, but it is not mandatory. Include page or paragraph numbers if it will help reader find the information.
