Place quotations of 40 or more words in block form: Indent the entire quotation five to seven spaces, or 1/2 in. (the same distance you indent the first line of a paragraph). An example of the formatting of a paragraph containing a block quotation follows:

             Each paragraph of your text begins with an indent of five to

        seven spaces, or 1/2 in., from the left margin. Block quotations

        are often introduced with a colon:

             Indent the whole block quotation as far as the first line of

             a normal paragraph of text. Don't put quotation marks around

             it. If the source you are quoting includes quotation marks,

             you should include them "as they appear in the original."
         
                  If the block quotation has more than one paragraph,

             indent the first line of each additional paragraph five to

             seven spaces or 1/2 in. from the new margin. The parenthetical

             citation (or the page number[s],if the author and date are

             used to introduce the quote) follows the final punctuation mark

             of the block quotation, with no period after the closing

             parenthesis. (Author, 2001, page 000)

Below is an example of an actual block quotation and its introduction:

             According to Greenberg (2001), two different criteria were

        proposed to determine brain death: the "higher-brain" and the

        "whole-brain" concepts. He describes the higher-brain formulation

        as follows:
      
             A brain-dead person is alleged to be dead because his

             neocortex, the seat of consciousness, has been destroyed.
 
             He has thus lost the ability to think and feel-—the

             capacity for personhood--that makes us who we are, and

             our lives worth living. (pp. 37-38)

(The full reference to Greenberg is Greenberg, G. (2001, August 13). As good as dead: Is there really such a thing as brain death? New Yorker, 36-41.)
