If your citation carries down to a second line, make sure to indent the second line one tab.
NOTE: The titles of books and articles have unique capitalization rules. You will only capitalize the first word of the title, the first word after punctuation in the title, and proper nouns. For example, the book Nebraska Nursing: A Comprehensive Guide will be cited as Nebraska nursing: A comprehensive guide. While book and article titles follow these rules, the title of the actual journal will always be fully capitalized.
