Citing sources in APA style

Crediting sources and formatting references according to the style of the American Psychological Association (APA). Based on the 6th edition of the Publication Manual of the APA.

Chapters in edited books: general form

The formats for references to chapters in edited books are:

Author, A. A., & Author, B. B. (year). Title of the chapter or entry. In A. Editor, B. Editor, & C. C. Editor (Eds.), Title of the book (pp. xxx-xxx). Location: Publisher.

Author, A. A., & Author, B. B. (year). Title of the chapter or entry. In A. Editor, B. Editor, & C. C. Editor (Eds.), Title of the book (pp. xxx-xxx). Retrieved from http://www.xxxxx

Author, A. A., & Author, B. B. (year). Title of the chapter or entry. In A. Editor, B. Editor, & C. C. Editor (Eds.), Title of the book (pp. xxx-xxx).

  • An edited book is a book with chapters written by different authors. For the book as a whole one or more editors are responsible.
  • If there is no author, the title of the chapter or entry is placed in the author position.
  • The editors of the book are preceded by the word "In". After their names you place the abbreviation (Ed.) or (Eds.); please note the position of the initials. Here they are placed before the surname. Normally you mention them after the surname.
  • Following the title of the book you place the page numbers of the chapter or entry in parentheses. These are preceded by pp. (in case the chapter or entry has more than one page) and p. (in case there is only one page). This is different from other forms of using page numbers in APA style where the abbreviations pp. or p. are not used. If there are no page numbers, the chapter or entry title is sufficient.
