In-Text Citation Style
Version Date: April 27, 2011
This article provides guidelines for creating APA-style in-text
citations for your paper. The examples here are based on the sixth
edition of the Publication Manual of
the American Psychological
Association (2010). The information here covers the most common
of sources and citations you will encounter, but it is not a substitute
for the Manual itself.
Following are the guidelines for in-text APA citation, together with
The goal of the entire in-text citation and References page apparatus
is to provide your reader with an easy, clear way to locate the sources
you have drawn upon when writing your paper. Each in-text citation
serves as a key to a specific entry in the list of References at the
end of the paper. It
is therefore crucial that each key matches the appropriate reference
work. The references are alphabetized to make matching the citation to
the work quick and easy. As a last measure of quality control, then,
double check to be sure that each citation in your paper matches a work
in the References.
1: Basic Citation.
The APA uses an Author-and-Date system as the basic citation. The
author’s last name and the year of the publication (whether periodical,
book, or other source) is listed. Many writers using APA style include
citations that refer to an entire article or book, so page numbers are
often absent. Thus, (Jones, 2009)
refers to the entire work, while
(Jones, 2009, p. 123) refers
to a page in the Jones book or article.
Note by these examples that you have some variety and flexibility in
presenting the required elements.
After the crash, Doe (2005) reported that many victims were unable to
explain what had happened.
Jones (2010) produced the most recent study.
The most recent study was completed in 2010 in Australia (Jones).
There has been a recent study (Jones, 2010).
2: Short Quotations.
When quoting fewer than forty words (or fewer than four lines) from a
source, enclose the quotation in quotation marks and include
• the author’s last name
• year of publication
• and page number, preceded by the letter p, outside
the quotation marks.
Jones (2009) discovered that “some respondents were not entirely
truthful” (p. 245).
A new analysis of the data revealed, “The number of outliers was
unusually high” (Jones & Smith, 2008, p. 321).
In early 2007, Smith found that “reports of Munchausen-by-proxy were on
the increase” (p. 123).
3: Long Quotations.
When quoting more than forty words (or more than four lines) from a
source, create a block quotation that
• includes an introductory lead-in
• begins on a new line
• is indented one-half inch from the left margin
• does not use quotation marks
• includes the page number(s) preceded by p. or pp.
after the period at the end of the quotation
Unfortunately, Doe (2010) not only fails to meet Jones’ arguments head
on, countering them with better data or research, but he instead takes
up the cudgels of ad hominem and merely attacks the messenger:
Except for a complete lack of data, the
work of Jones (2008) is very
scientific. It’s real value, however, lies not in a report of what’s
new, but in revealing to us that his own knowledge base consists of an
excellent compendium of half truths, misinformation, urban legends,
propaganda, hyperbole, advertising claims (am I being redundant here?),
tall tales, and factoids. His reasoning process is indeed staggering.
4: Two Authors.
When a source has two authors, always
• cite both last names each time
• connect them with the word and for in-text citation
• connect them with an ampersand (&) for
parenthetical citation (Example 5)
An experiment by Doe and Smith (2001) produced “an unusually high
proportion of outliers” (p. 123).
An experiment to test these effects produced “an unusually high
proportion of outliers” (Doe & Smith, 2001, p. 123).
5: Three or More Authors.
When a source has three, four, or five authors, include all last names
in the first citation, and then use the first author’s last name
followed by the Latin abbreviation et al. for subsequent citations. The
et al. is not italicized and includes a period as Examples 6 and 7
A ten-year study by Jones, Doe, Smith, Brown, and Doax (2003) revealed
that “linguistic changes can complicate longitudinal investigations”
Further, Jones et al. concluded that “future research must be more
sensitive to the question of linguistic variability” (p. 444).
A ten-year study published in 2003 revealed that “linguistic changes
can complicate longitudinal investigations” (Jones, Doe, Smith, Brown,
& Doax, p. 432).
Further, the study concluded that “future research must be more
sensitive to the question of linguistic variability” (Jones et al., p.
For more than five authors, cite only the first author’s last name
followed by et al.
6: No Author
When a source such as a newspaper article or Web page does not list an
author, the References page will enter it by title. For the in-text
citation, then, reference it by the first few words of the title.
Remember that the purpose of the in-text citation is to allow your
reader to turn to the References page and locate the full bibliographic
entry quickly and easily.

taking their materials far beyond traditional instructional design
principles (“New Focus,” 2009).
