* Citation style: This is the most common and widely understood term. It refers to a specific set of rules for formatting citations within the text and the corresponding reference list at the end. Examples include APA, MLA, Chicago, and Harvard.
* Reference style: Similar to citation style, this term emphasizes the formatting of the reference list itself.
* Bibliographic style: This is a more formal and comprehensive term that encompasses both in-text citations and the reference list, often including details about formatting titles, author names, and publication information.
* Citation format: This term focuses on the structural aspects of how citations are presented.
* Documentation style: A broader term that includes not only the referencing system but also other aspects of academic writing related to acknowledging sources (e.g., footnotes, endnotes).
In short, while "citation style" is probably the most commonly used and easily understood term, all of the above refer to the rules for creating a consistent and accurate list of references in academic work.
