Chicago A

Chicago A reference style (Notes and Bibliography)

Chicago referansestil is available in two variants:

  • Chicago A - Notes and Bibliography. 
  • Chicago B - Author-Date

Current version of the style is Chicago 17th.

 

About the footnote style

Chicago A (footnote style) is commonly used within humanities, e.g., in literature science, historic-philosophical subjects and art history. The style uses numbered footnotes or end notes (1, 2, 3 etc.) to cite sources.  

The sources are usually also added to a corresponding bibliography. The footnote and bibliographical style can contain a wide range of sources, including unusual sources that do not fit the author-date style very well. Another advantage is that the text is not interrupted by bibliographical information. Using notes also gives room to comment on the various references. 

Guidelines

Titles

Book titles and journal titles are in italic. Italic is also used for newspaper titles and blogs, films, videogames, materials, and other types. Titles of articles and chapters are enclosed in quotation marks. Quotation marks are generally reserved for the titles of subsections of larger works. 

Text quotes

Short quotations are enclosed in quotation marks, “such as this”. Longer quotations are put in a separate block. Direct quotes should not be enclosed in quotation marks, and they should always start on a new line. They are further separated from the text by indentation from the left (and sometimes from the right). 

Bibliography

The bibliography should have hanging indents, meaning that all lines after the first in each entry are indented. 

Multiple publications by the same author

Use a long line instead for the author’s name, and the publications will be put in alphabetical order, see the example under.

ChatGPT and artificial intelligence

Please make sure that you follow guidelines on permitted aids. Be aware that ChatGPT and other artificial intelligence tools are not always allowed at exams and other papers etc. Please check the guidelines for your faculty/ institute. 

The Chicago styles recommends that references to ChatGPT and other similar services are treated the same way as personal communication. Personal communication and text generated by large language models cannot be reproduced or found, and they should therefore not appear in the reference list.

Chicago A - by example

Publications with multiple authors (or editors) 

Two or three authors (or editors) of the same work are listed in the order in which they appear. In the bibliography, only the first author’s name is inverted (Surname, First name), while other names are First name Surname. 

Publications written or edited by four – ten persons usually have all names given in the bibliography. 

Online Sources 

URL or DOI should be included. Reading date as well, especially if it is a source under continuous update or changes.  
If there is a DOI-number, e.g., for a article, it should also be included. DOI should be written: https://doi.org/...  

Rapports etc. 

Flyers, rapports, pamphlets and other free publications are sorted as books. Author and publisher data may not fit the usual pattern, but sufficient information should be provided to identify the document. 

Laws 

Chicago recommends The Blue Book: A Uniform System of Citation, published by the Harvard Law Review Association, to cite legal and public documents, statutes, and other government documents. Laws are usually not placed in the bibliography, only in the footnote. See The Chicago Manual of Style for detailed information.  

Art 

Information about paintings, photographs, sculptures, or other art is usually presented in the text instead of footnotes or the bibliography. If a note or some other bibliographic information is necessary, write the artist's name, the art title (in italics) and the date/year, followed by information about the art and placement of the art. Eventually add a URL. 

Personal communication 

It is usually cited in the text only or in a note, not in the bibliography.  

 

References in notes 

To reduce the amount of documentation, subsequent source citations already given in full should be shortened whenever possible. If you include a full bibliography at the end of your document, you should use a shorter format in all notes. 

For publications written or edited by four – ten persons, only the name of the first author is included in the note, followed by “et al.”.   

"Ibid." With repetitive use of the same source is not recommended in this version of Chicago footnote style. "Op. cit." og "loc. cit." are no longer allowed.
