CSE Formatting

CSE style, formerly called CBE style, refers to the citation style established by the Council of Science Editors. CSE is the format preferred by writers in many disciplines in the natural sciences, including biology, geology, chemistry, mathematics, and physics. CSE style provides two different citation systems: the Name-Year system and the Citation-Sequence system (sometimes called the Superscript system). These systems differ in their presentation of in-text citations and in the way works cited are listed.

CSE Style: In-text Citations (Name-Year System)

In the Name-Year system, citations are provided in the main text through parenthetical citations. Citations precede the final punctuation of the sentence that contains the reference. The basic elements of the in-text citation are the author's last name and the year of publication of the work. A space separates the name and the year.
