The mistakes in Georgia's entry are the following:
First, the author's surname is followed by his or her initials and the year of publication within parenthesis. Then, the title of the book should be written in italics. After the city and state of publication, a colon or full stop are located in front of the publishing company. For example:
Caffin, C. (1912). Roughing Them Up. New York, NY: Print.
