APA Citation Style Guide

This guide will support you in creating common citation formats in the APA (American Psychological Association) Style - 7th edition.

Quick tips

All books

  • "For works that stand alone (e.g., books, reports, webpages and websites), italicize the title, and capitalize it using sentence case (see Section 6.17)."
  • Additional information such as edition, volume number should be in brackets directly following the title, not separated by a period or comma, and not italicized.
    (APA, 2020, p. 291)


  • Include a DOI if provided. If a DOI is not available, include a permanent URL, if provided.
    • DOI: Digital Object Identifier. A string of letters and numbers that specifies a unique object. DOIs begin with 10 (e.g. 10.1093/rheumatology/key279)
    • add to make a live link (e.g.‚Äč)
  • If the e-book was retrieved from a commonly accessible database (e.g. ProQuest,  EBSCO, Science Direct, Elsevier etc.) do not include the URL (APA, 2020, p. 321). 
  • "Links should be live if the work is to be published or read online." (APA, 2020, p. 299). This includes DOIs and URLs.

  • Call Number: Unique alphanumeric number, often on the spine of a book. Classifies books by topic, e.g. QA75 for computer science.
  • ISBN: International Standard Book Number. Unique fifteen digit number, usually with a barcode. Printed in book, often on back cover.
