CSE Citation Style

CSE Style

The Council of Science Editors (CSE), formerly the CBE (Council of Biology Editors), produces a guide to appropriate scientific style used for citing sources in the sciences, which includes biology, chemistry, computer science, engineering, geology, mathematics and physics. The guide is referred to as "the CSE Manual." For more detailed information, see these websites:

CSE does not prescribe a paper format, but the library recommends using 12-point Times New Roman, double-spaced with one-inch margins top, bottom and sides.

CSE citation style and a few rules

Examples of citations of different formats in CSE Name-Year

A few rules about CSE Name-Year system:

  • Authors’ first names are written as capitals after their surnames; i.e., Ríos JB, Jones TL, Cho J.
  • Titles of articles, chapters, journals and books are not italicized.
  • Only the first word in a title of a book or article is capitalized.
  • Only species' names are italicized; i.e., Sequoia sempervirens or Olea europaea.

The two types of citations are "end references," which are listed on your References or Cited References page, and "in text references," which are inserted within the text of your paper in the paragraph in which you cite that source. Reference pages are formatted with a hanging indent; i.e., the second line of a citation is indented. In the name-year system, list (but do not number) your sources alphabetically in the reference list at the end of your paper. In the sentences of your paper, cite these sources by giving the author’s last name and year of publication in parentheses.
