APA style requires that any quotations of 40 words or more be structured as a block quote. According the 6th edition of the APA Style Guide (sections 4.08 and 6.03):
If a quotation comprises 40 or more words, display it in a freestanding block of text and omit the quotation marks. Start such a block quote on a new line and indent the block about a half inch from the left margin (in the same position as a new paragraph). If there are additional paragraphs within the quotation, indent the first line of each an additional half inch. Double-space the entire quotation. At the end of a block quote, cite the quoted source and the page or paragraph number in parenthese after the final punctuation mark. Alternatively, if the quoted source is cited in the sentence introducing the block quote, only the page or paragraph number is needed at the end of the quotation.
Example:
Miele (1993) found the following:
The "placebo effect," which had been verified in previous studies, disappeared when behaviors were studied in this manner. Furthermore, the behaviors were never exhibited again [emphasis added], even when reel [sic] drugs were administered. Earlier studies (e.g., Abdullah, 1984; Fox, 1979) were clearly premature in attributing the results to a placebo effect. (p. 276)
To format a block quote in Word:
- Type in the quote on a new line in your document.
- Highlight the quote and select the indent symbol in the Paragraph toolbar, as shown below.
- The default is .5", which is what APA requires.
