It is important to make sure and give credit when using others' ideas or words in your work. Check with your instructor if you are uncertain as to which style guide is recommended for your particular class assignment. For more information on when to cite, see our page on Avoiding Plagiarism.
If you don't see an example of what you need on this website or want to look at other citation styles, and other books on citation style, check the Oregon Tech Library reference section in Klamath Falls and Wilsonville, or search the online catalog for an electronic version.
Chicago Manual of Style
The Oregon Tech Library provides this abbreviated guide to documentation of sources for academic and professional writings. The guide is based on The Chicago Manual of Style, 16th ed. Chicago: University of Chicago Press, 2010. The manual is located in course reserves.
The two citation systems of the Chicago citation style are widely used in academic institutions; the choice between the two is based on a specific discipline and subject.
- The Turabian system is used for citing sources in literature, history and the arts
- The Author-Date system is used for citing sources in physical, natural, and social sciences
Oregon Tech programs typically use the Author-Date system when assigning Chicago Style.
Council of Science Editors (CSE) Style
CSE style, formerly known as Council of Biology Editors (CBE) style, is most frequently used in the fields of biology and environmental sciences.
There are three possible formats in this style:
- Citation-sequence: references are numbered and listed in the order they are mentioned in the paper; uses superscript numbers
- Name-year: unnumbered references are listed in alphabetical order
- Citation-name (combines aspects of the two): references are arranged alphabetically and are numbered sequentially
