Referencing Styles

A guide to the reference styles used at the University of St Andrews

Important:

The pages of this guide related to the guidelines in the Chicago Manual of Style - 18th edition, published in 2024.  This edition of the style is gradually being adopted by the Schools who recommend or require this style for coursework submissions.

During academic year 2024-25 students using the Chicago style are advised to use the following version of the Chicago style:

  • Art History - use the 17th edition of the Chicago Manual of Style for this academic year, the 18th edition will be adopted in academic year 2025-26
  • Divinity - use either the 17th edition or the 18th edition of the Chicago Manual of Style for this academic year, applying either version consistently (i.e. do no use a combination of both)
  • Other Schools, consult the Student Handbook for your School, or ask in your School for advice.

  • Editors - "eds" is not added to the in-text citation but is added to the reference in the reference list.

Author-date

For a source with more than two authors or editors list the names of up to six  in the reference list in the order they are given in the source. 

In the reference list the First author or editor is given by surname, first name, the following authors or editors are given as First name and surname.

In the reference list a comma is used between each authors name and the word 'and' is used between the penultimate author or editor and the final author or editor.

Where there are more than two authors or editors the in-text citation should give the surname of the first author or editor followed by et al.

In-text citation:  (Surname of first author/editor et al. Year, Page)

Example: 

(Dees, et al. 2001, 170)

Reference List:  Surname, First Name, First Name Surname, and First Name Surname. Year. Title. Publisher.

Where a resource is published by an organisation, and where no individual is identified as the author/editor, use the organisation full name in place of an author/editor.

If the author or editor is unknown, the in-text citation includes a shortened, italicised Title in place of the Author, which must include the first significant word of the title. The entry in the reference list should begin with the title.  Entries in the Reference List are alphabetised from the first significant word (excluding words like "A", "The", "An", etc.).

Where an author or editor if known or guessed at, but the details are not included on the title page of the resource, the name is included in square brackets in both the in-text citation and Reference List.
