It can be frustrating to have to use different citation styles for different classes! But, there are reasons that different disciplines use different styles of citation. While there are dozens of different citation styles, all citations, regardless of style, will contain substantially the same bits of information about the source necessary for the reader to track it down. Differences in citation styles come down to formatting differences in the order of the information elements, capitalization, punctuation, and presentation of the author’s name, as well as how the individual references are presented within the text. Most citation styles can be broadly classified into two systems for referencing: 1) parenthetical (in-text) citations and 2) numbered citations.
Style manuals and guides dictate more than just in-text citation and reference list formatting. They also have rules for how to structure your paper and, in some cases, the cover sheet for your paper. Don't worry, each citation style has its own manual to help you figure out exactly how it all works.
