Write your paper and build up context for a block quote.
Copy the material you wish to quote directly nto the word processor window. Do not worry about formatting it just yet. Copy it into the paper as if it were a paragraph unto itself and do not use quotation marks.
Move your mouse pointer to the beginning of the quoted paragraph and select the entire quotation.
Move the margins five spaces over. In most word processors, this can be done by adjusting the ruler at the top of the text-entry box.
Set up the block quote in the paragraph directly preceding it. You should contextualize the source completely by stating the author's name and summarizing where the quote comes from.
Add MLA style citation material. If in your contextualizing lead up, you mention the author's name, you only need a parenthetical page number at the end of the block quote. For example: This quotation represents the last sentence of a block quote without quotation marks. (183)
Add the author's name if you did no contextualization whatsoever. For example in MLA style: This quotation represents the last sentence of a block quote without quotation marks. (Authorname 183)
Use the APA style, if that was part of the paper's assignment. You will need the year of publication and page number to do this. Contextualizing the source ahead of time looks like this: As A. Authorname (2011) writes, This represents the body of the block quote without quotation marks. (p. 183)
Put the full APA citation at the end of the quote if you do not contextualize the author and the source. For example: This represents the body of the block quote without quotation marks. (Authorname 2011, p.183)
