The Council of Science Editors (CSE) offers three systems of documentation. In all three systems, a reference list at the end of the paper provides all the information your reader needs to track down your sources. In-text references in your sentences show your reader which sources support the claims and information of that sentence.
The systems differ in the details of how they format in-text references and how they organize the reference list. For more information about each system, click on the appropriate link below:
Example from Charkowski (2012):
Example from Newbury (2013):
Example from Wattiaux (2005):
For a class paper, check to see if your instructor prefers one of these systems. For a journal article, check the journal's instructions to authors to find out which system to use.
For a full description of these systems and the philosophy behind them, consult Scientific Style and Format: The CSE Manual for Authors, Editors, and Publishers, the Seventh Edition (2006) of the CSE manual.
