APA 7th Edition - Citation Guide - CBS Library

Repeating a Citation (Do NOT use ibid.)

When repeating a citation, show the entire citation; do not, for example, include only a page number (the abbreviation “ibid.” is not used in APA Style). Instead, use the following guidelines:

  • Include the author(s) and year for every parenthetical in-text citation.
  • Do not repeat the year for narrative in-text citations the second and subsequent times they appear in a single paragraph. Follow this guideline with each new paragraph (i.e., include the year in the first narrative citation in a new paragraph).
  • However, if you cite multiple works by the same author or authors, regardless of the publication years, include the date in every in-text citation to prevent ambiguity. For example, if you cite Mohammed and Mahfouz (2017) and Mohammed and Mahfouz (2019), include the year with every citation, even when one of the references is cited multiple times in a single paragraph.
