Council of Science Editors

CSE style is maintained by the Council of Science Editors to promote the publication of scientific scholarship across many science fields. Because it serves a wide range of fields, CSE style offers two distinct citation styles: Citation-Sequence and Name-Year. Determine which style is appropriate and use it consistently. For additional guidance, please visit the CSE Citation Quick Guide.

CSE Name-Year Guidance

When using Name-Year, use an in-text citation with the author's surname and the publication year in parentheses. If there is more than one author, only include the first author's surname followed by "et al." For example:

  • (Laskowski 2002)
  • (Gardos et al. 1988)

In the reference page, order the sources alphabetically by the first author's surname. For multiple sources by the same author, order them chronologically by publication year. Entries with more than ten authors list the first ten authors followed by "et al." References should have a hanging indent (the first line is not indented, and all additional lines are indented .5 inches).


The "extent" of a book could include its page numbers or its volume number. The "notes" can include optional information of interest to the reader like the language or required information like the URL of an online work.
