Type the quote, paraphrased information or summarized information in the essay.
Type the last name of the author of the work you're citing. If there are two authors, type both names separated by "and." If there are more than two authors, type the first two authors separated by commas and then et al. For example, "Smith, Johnson, et al."
Add a comma after the last name listed or after et al.
Type the source's page number or numbers where you found the information after the comma.
Surround the entire citation with parentheses.
Place a period after the parentheses. Your final citation should look something like: "(Smith and Johnson, 18-21)."
