  4. Three to five authors
  5. Six or more authors

31a. APA in-text citations

The APA's in-text citations provide at least the author's last name and the date of publication. For direct quotations, a page number is given as well.

NOTE: In the models that follow, notice that APA style requires the use of the past tense or the present perfect tense in signal phrases introducing material that has been cites: Smith reported, Smith has argued.

1. A quotation. Ordinarily, introduce the quotation with a signal phrase that includes the author's last name followed by the date of publication in parentheses. Put the page number in parentheses at the end of the quotation.

 

31b. APA list of references

In APA style, the alphabetical list of works cited is titled "References." Following are models illustrating the form that APA recommends for entries in the list of references. Observe all details: capitalization, punctuation, underlining, and so on. For explanations of these matters and for a sample "References" page, see pages 132 and 136.
