When quoting directly from a source, you should use quotation marks around the exact words of the speaker and provide a citation to the source, including the author's name, the title of the work, and the page number where the quote appears. For example:
"I have a dream that one day this nation will rise up and live out the true meaning of its creed: 'We hold these truths to be self-evident, that all men are created equal'" (King, "I Have a Dream," p. 4).
You should also use proper punctuation and formatting when quoting directly from a source, such as placing punctuation marks inside the quotation marks if they are part of the quote, and using ellipses (...) to indicate omitted text.
