APA Citation Style: Books

When Citing a book...

Each citation should contain the following information:

  • Author - Last name, initials for first and middle name.
  • Publication date - Put the date in parenthesis.
  • Title - Write the title in italics and capitalize only the first word of the title.
  • Place of Publication
  • Publisher

Complete citations are placed on the References page at the end of the paper.

Parenthetical Citations appear immediately after the source is referenced in your paper. There are two types of parenthetical citations: 

  • In-Text Citation (Paraphrase) -use this when you express the ideas of a researcher or author using your own words.  
  • In-Text Citation (Quotation) - use this when you use a direct quote from your source.

***  If the book has an editor instead of an author, insert the editor's name in the place of the author's name  followed by (Ed.) .
