Answer:
It depends on the source of the famous quote.
Explanation:
If you are quoting from a website, you should consider doing it the following way:
Last name, Name. "Title of the article". Webpage name. Name of the organization (if necessary). Day month year of publication (if existing). Way of publication (web, in this case). Date when the website was visited. <link to the website>
If there's no name, you should start with the title of the article. The first date is when the article came out, the second one, when in was visited.
Inside the text, you should quote like (Last name, par. number).
