Chicago Manual of Style (English): Style I: Notes and Bibliography

What is the “Notes and Bibliography” style?


The Notes and Bibliography citation style is primarily used in the humanities, such as history, literature studies, and (continental) philosophy. Source citations are shown in footnotes at the bottom of each page or in endnotes at the end of the paper. Each citation has a number that corresponds to a number in the body of the text. There is a bibliography at the end of the paper in which all works are stated again. Each publication type determines how you have to cite the sources used. Citations in footnotes or endnotes look different than references in the bibliography.

Some general rules:

  • In the first citation of a specific publication in the footnotes or endnotes, you provide complete information on the source. In subsequent citations to the same publication, you can use an abbreviated version.
  • In the footnotes and endnotes, the different components of the citation are distinguished using commas. For example, a comma must be placed between the name of the author and the title. Please note that there no comma is placed before the publication information.
  • In the bibliography, the different components of the citation are distinguished using full stops.
  • Preferably use the full given name instead of initials. Except for authors who always use initials, for example C.S. Lewis. 
  • The title of a book or journal must be in italics.
  • The title of a chapter or article is placed between quotation marks.
  • All references end with a full stop, in the footnotes and endnotes as well as in the bibliography. 

Common publication types with examples

Citing a book with a single author

In the footnotes or endnotes:

In the first citation of a specific book in the footnotes or endnotes, you provide complete information on the source.

  • The first name and surname of the author. Initials for authors who always only use their initials, but preferably you supply their full names.
  • The title of the book in italics.
  • ​The publisher and the year in which the work was published are placed between brackets.
    • CMS no longer prescribes mentioning the place of publication. Only provide it if this is relevant for the reader.
  • ​The page number(s) if you cite or refer to a specific passage.
  • An e-book requires a URL or DOI

The different components of a citation are separated using commas (with the exception the title and subtitle) and you end the citation with a full stop. In subsequent citations to the same book, you can use an abbreviated version. Below is an example of how a citation should look:

1.      First name Surname, Full title in italics: Subtitle (Publisher, year), page number.

2.      First name Surname, Full title in italics: Subtitle (Publisher, year), URL or DOI.

3.      Surname, Abbr. title in italics, page number.


4.      Gert-Jan van der Heiden, Ontology after Ontotheology: Plurality, Event, and Contingency in Contemporary Philosophy (Duquesne University Press, 2015).

5.      Van der Heiden, Ontology after Ontotheology, 230.

In the bibliography:

In the bibliography, you provide the surname and first name of the author or editor, the full title and subtitle in italics and the year of publication (not between brackets in the bibliography). The different components of the citation are distinguished using full stops (not with commas as in the footnotes and endnotes). A book citation appears in the bibliography as follows:

Surname, First name. Full title and subtitle in italics. Publisher, year of publication.

Van der Heiden, Gert-Jan. Ontology after Ontotheology: Plurality, Event, and Contingency in Contemporary Philosophy. Duquesne University Press, 2015.


​Citing a book with two or more authors (or editors)

In the footnotes or endnotes:

In the case of one or two authors/editors, se the same order of names as on the title page of the book. The names are separated using commas and the last name is preceded by “and”. If you are referring to editors, place “ed.” (one editor) or "eds." (multiple editors) after the last editor. In the case of more than two authors/editors, only provide the name of the first and follow with 'et al.' (from the Latin et alia: 'and others').

1.      First name Surname et al. eds., Full title in italics: Subtitle (Publisher, year), page number.

2.      Surname et al., Abbr. title in italics, page number.

3.      Chris Hermans et al., eds., Social Constructionism and Theology. (Brill, 2002).​
 

In the bibliography:

In the bibliography, the surname of the first author comes first, followed by a comma and the first name of the first author. For subsequent authors, the first name comes first and is followed by the surname. In the case of more than six authors/editors, only provide the names of the first three, followed by 'et al.'

Surname, First name, First name Surname, and First name Surname. Full title and subtitle in italics. Publisher, year of publication.

Encyclopaedias

If you consulted a well-known encyclopaedia (or other reference work), it suffices to cite the reference work in the footnotes or endnotes only.  Whether you include the reference in your bibliography as well depends on what kind of encyclopaedia it is. Since rule leaves room for doubt, we recommend that you also include a reference to the encyclopaedia in the bibliography when you are not sure. Please note that there are multiple ways to cite an entry from an encyclopaedia. If it concerns a comprehensive entry that states the author’s name, as in the examples below from Stanford Encyclopedia of Philosophy or Encyclopedia of Christianity Online, the citation is structured differently. See the example below for such a citation.

Citing an encyclopaedia

In the endnotes or footnotes:

  • Title of the encyclopaedia in italics
  • s.v. (From Latin sub verbo: "under the word") and the entry consulted between quotation marks
  • Date of publication or revision (if this is stated) or the date consulted
  • URL or DOI

1.      Title of the encyclopaedia, s.v. "Entry," consulted on 03-07-2017, URL or DOI.

2.      Title of the encyclopaedia, s.v. "Entry," last modified on 21-12-2016, URL or DOI.

In the bibliography:

Title of the Encyclopaedia in italics. 1st ed. Publisher, year of publication. URL or DOI.

Title of the Encyclopaedia in italics. Consulted on 03-07-2017. URL or DOI.

Title of the Encyclopaedia in italics. Last modified on 21-12-2016. URL or DOI.

 


​Stating the author

If the encyclopaedia consists of substantial entries of which the author is known, it can also be relevant to specify the author of the article from the encyclopaedia. Examples of these include extensive articles from the Stanford Encyclopaedia of Philosophy and the Encyclopaedia of Christianity Online. If the author of the entry is indicated in the citation, it will look like a citation for a contribution to a book with multiple authors. 

In the endnotes or footnotes:

1.      First name, Surname, "Title of entry," in Title of Encyclopaedia (Publisher, year of publication).

2.      First name, Surname, "Title of entry," in Title of Encyclopaedia, consulted on 03-07-2017, URL or DOI.

In the bibliography:

First name, Surname "Title of the entry." In Title of the Encyclopaedia. Encyclopaedia publication information. Article publication information or date consulted. DOI or URL.

Citing a website

It is often sufficient to simply mention a website in the text or include a citation in the footnotes or endnotes only. Since the content of websites changes often, it is recommended that you state the date you accessed it or the date it was last modified. 

The following components may appear in the citation:

  • The title of the page or a description of the page
  • The author (if stated)
  • The owner of the site
  • URL
  • Publication date or the date it was last modified. If no date is given for when the page was published or last modified, provide the date that you accessed the page. 

In the footnotes or endnotes:

1.      "Title or description of the page," Author, Site owner, date of publication/modification/access, URL.

In the bibliography:

Owner or author. "Title of the page or a description of the page." Date of publication/modification/access. URL.

Geestelijke verzorging in Nederland. "Wat is geestelijke verzorging." Accessed August 12, 2025. https://geestelijkeverzorging.nl/wat-is-geestelijke-verzorging/

A report, mission statement, pamphlet, folder or related source is treated similar to a book. It is not always possible to map all elements of a book citation, but you should provide as much elements as possible to make sure your source can be identified.

  • Author (or organisation)
  • Year
  • Title in italics
  • Publisher (or organisation)
  • URL

If no authors are listed, you can cite according to the title. In that case, also alphabetize according to title in the bibliography. Sometimes it is more fitting to treat the organisation as author, for example when an organisation publishes a pamphlet without listing the authors.
