References In the text



Sources are cited in the text, usually in parentheses, by the author’s surname, the publication date of the work cited, and a page number if necessary. Full details are given in the reference list (under the heading References). Place the reference at the appropriate point in the text; normally just before punctuation. If the author’s name appears in the text, it is not necessary to repeat it, but the date should follow immediately:

Jones and Green (2012, 50) did useful work on this subject.

Khan’s (2012) research is valuable.

Khan (2012, 89) says, “If the reference is in parentheses, use square brackets for additional parentheses.” 

Within the same parentheses

Separate the references with semicolons. The order of the references is flexible, so this can be alphabetical, chronological, or in order of importance, depending on the preference of the author of the article. If citing more than one work by an author, do not repeat the name:

(Smith 2010, 2012; Khan 2012)

(Smith 2010, 2012, 84; Khan 2012, 54–60)

(Smith 2012a, 84, 95–102; 2012b, 82; Khan 2012, 9)

(Smith 2010, 12; 2012, 84; Khan 2012, 9)

Repeat mentions in the same paragraph

Place the parenthetical citation after the last reference in the paragraph or at the end of the paragraph before the final full stop (period). If the reference is to a different page, however, put the full citation at the first reference and then include only the page number at the next mention:

“Text” (Smith 2012, 54) . . . more text . . . “quoted text” (68).

With a quotation

Citation of the source normally follows a quotation, but may be placed before the quotation to allow the date to appear with the author’s name:

As Smith (2012, 67) points out, “quoted text.”

As Smith points out, “quoted text” (2012, 67).

After a displayed quotation, the source appears in parentheses after the final punctuation:

. . . end of displayed quotation. (Smith 2012, 67)

Page number or other locator

(Smith 2012, 6–10)

(Jones 2012, vol. 2)

One author

Smith (2012) or (Smith 2012)

Two authors

Smith and Jones (2012) or (Smith and Jones 2012)

Three authors

Smith, Jones, and Khan 2012 or (Smith, Jones, and Khan 2012)

Four or more authors

Smith et al. (2012)

(Smith et al. 2012)

If the reference list contains two publications in the same year that would both shorten to the same form (e.g. Smith et al. 2012), cite the surnames of the first author and as many others as necessary to distinguish the two references, followed by comma and et al. (NB: you cannot use et al. unless it stands for two authors or more.). If this would result in more than three names having to be used, cite the first author plus a short title:

(Smith et al., “Short Title,” 2012a)

(Smith et al., “Abbreviated Title,” 2012b)

Authors with same surname

(G. Smith 2012)

(F. Smith 2008)

No author

Cite first few words of title (in quotation marks or italics depending on journal style for that type of work), plus the year. Or use newspaper or magazine’s title in italic instead of author’s name:

(China Daily 2013, 12)

Groups of authors that would shorten to the same form

Cite the surnames of the first author and as many others as necessary to distinguish the two references, followed by comma and et al.

Organization as author

The organization can be listed under its abbreviation so that the text citation is shorter. If this is the case, alphabetize the reference under the abbreviation rather than the full name:

British Standards Institution (BSI)

In the text:

(BSI 2012)

In the reference list:

BSI (British Standards Institution). 2012. Title

Author with two works in the same year

Put a, b, c after the year 

(Chen 2011a, 2011b)

(Chen 2011a)

(Chen 2011b)

Chen, Z. 2011a. The Economy of China

Chen, Z. 2011b. The Labor of Value

Secondary source

When it is not possible to see an original document, cite the source of your information on it; do not cite the original assuming that the secondary source is correct.

Smith’s diary (quoted in Khan 2012, 193)

Classical work

Classical primary source references are given in the text, not in the reference list.

Personal communication

References to personal communications are cited only in the text:

A. Colleague (personal communication, April 12, 2011)

Unknown date

(Author, n.d.)

(Author, forthcoming)

Two dates

List the original date first, in square brackets, but in parentheses in reference list:

Smith ([1890] 1983) said . . .

Smith, J., ed. (1890) 1983. Collected Style Manuals. Abingdon: Routledge.

Multivolume works:

(Author 1951–1971)


Endnotes should be kept to a minimum. Any references cited in notes should be included in the reference list.

Tables and figures


References cited in tables or figure legends should be included in the reference list.

Source: Smith (2012, 197).

Reference list

Use the heading References. Do not use a 3-em dash to replace author names.


Alphabetically by last name of author. If no author or editor, order by title. Follow Chicago’s letter-by-letter system for alphabetizing entries. Names with particles (e.g., de, von, van den) should be alphabetized by the individual’s personal preference if known, or traditional usage.

A single-author entry precedes a multi-author entry that begins with the same name. Successive entries by two or more authors when only the first author is the same are alphabetized by co-authors’ last names. If references have the same author(s), editor(s), etc., arrange by year of publication, with undated works at the end.

If the reference list contains two or more items by the same author in the same year, add a, b, etc. and list them alphabetically by title of the work:


Green, M. L. 1998a. Book Title. Location: Press.

Green, M. L. 1998b. Title of Book. Location: Press.

Form of author name

Generally, use the form of the author name as it appears on the title page or head of an article, but this can be made consistent within the reference list if it is known that an author has used two different forms (e.g., Mary Louise Green and M. L. Green), to aid correct identification.


Headline-style capitalization is used. In headline style, the first and last words of title and subtitle and all other major words (nouns, pronouns, verbs, adjectives, adverbs) are capitalized. For non-English titles, use sentence-style capitalization.
