Type the quote. Ensure that it exceeds four typed lines of text, even if the quote does not start at the exact beginning of a line. An easy way to check this is to copy and paste the quote into a new document and see what the length of the quote is.
Type an opening sentence for the quote. This should be something that introduces and very briefly summarizes what the quote will be about. From here, type something like "[The author] writes:" and then press Enter. Ensure that you have ended this opening statement with a colon.
Type the quote on the line under the opening statement. Place a period at the end of the quote. Type one space and place the page number in parantheses after the quote. Do not put the author's name, as you already mentioned the author's name in the introductory statement for the quote.
Indent the quote one tab. All the margins of the quote must be aligned.
Continue writing the paper after you have finished the block quote. Press Enter once again to start on a new line, but do not create an actual space between the block quote and the text that follows. Start this new text at the left alignment, rather than indented as you did with the block quote.
