CSE Style Variations nsons

There are three acceptable styles in CSE:

  • Name-Year System or Harvard Style
  • Citation-Sequence System or Vancouver Style
  • Citation-Name System

The Harvard style uses in-text parenthetical citations and an alphabetical reference list.  In contrast, the Vancouver system and the Citation-Name system use superscript numbers which refer to a numerical reference list; each system varies on the arrangement of the reference list.

The CSE favours the Harvard Style (not to be confused with Harvard law style). Check with the professor, the department, or a leading journal to determine which CSE style is preferred for your specific course or discipline.
