Citation Explained
In this tutorial, you will learn when it
is necessary to cite and how to use correct APA format in your paper
and reference list. Quizzes allow you to test your knowledge as
you progress. Begin with Module 1 below.

Citing seems so picky and time consuming to me.
I think it is a waste of my time. Why do I need to cite?
- It ensures complete information is included
The structured format of a citation may seem unnecessarily limiting,
but it ensures that you include all the information a reader needs
in order to find the source to which you refer. If you have
ever had to trace a publication with inadequate or inaccurate
information, you will know how important it is to use a structured
format for references.
- It's the right thing to do!
Like correct grammar or proper spelling, good citation style
demonstrates your attention to detail, consideration for your
reader, and good organizational skills. It makes a favorable impression,
and may even influence your faculty member to look more favorably
on your work as a whole.
Thinking about citing can make you aware of factors that will
help you judge a paper. For instance, you need to include the
date of publication in a citation. Being forced to look for the
date for citing purposes is useful because currency is usually
an important factor in evaluating information. If you decide initially
that the date is too old, you will not have to spend time reading
the paper. Similarly, a reputable author or publisher or a scholarly
journal are additional clues that indicate a source is worth including
in your paper. You will be noticing and accumulating all of this
data while preparing to cite the resource.
| What
citing style should I use? |
|
There are several different styles for citing
resources in a research paper. Some of the most common include
American Psychological Association (APA), Modern Language Association
(MLA), Turabian, and Chicago. See the VAIL
citation tutorial overview for more information on these styles
and a more complete list of other possible styles.
In general, APA is most used in the sciences
and social sciences such as psychology, business and management,
while MLA is more frequently employed in the humanities. In addition
to the more common styles, you may also encounter styles specific
to a discipline. For example, medical professionals may use the
American Medical Association Manual of Style.
Is one style necessarily better than the others?
Not really. Indeed, some relatively expensive commercial software
products (ProCite, EndNote) allow you to convert from
one style to another with a few keystrokes.
We'll be talking more about these software products
in Module 4.
The important point is that, once you or your
faculty member chooses a style, you need to consistently use that
style. Just as you can't start measuring in inches and then switch
to centimeters midway through a project without producing a strange
construction, changing citation styles may produce a hybrid that
is missing information and hard to understand. Is "Joining" the
name of the article or the journal? Is "93" the volume number
or the year of publication? With a consistent citation style,
you make that information clear.
This tutorial will use American Psychological
Association (APA) style, although VAIL provides
a list of examples in both APA and MLA styles is available
for your use. APA is the style required by UMUC's Graduate School
and is widely used in the School of Undergraduate Studies. Examples
of APA style formatting, including electronic and print resources,
are provided at the end of this tutorial.
If you don't already have a print copy of the
Publication Manual of the American Psychological Association,
5th edition, you should consider purchasing one because you
will be referring to it throughout your studies at UMUC.
Each resource you cite is different, and you may well need
to refer to the print manual to find an example similar to the
format you need. Print copies of the manual can also be found
in most academic and many public libraries. Unfortunately,
a full edition of the Publication Manual of the American Psychological
Association, 5th edition, is not available in electronic form.
Please be aware that, because of the increased
use of electronic resources in research, there are considerable
differences between the 4th and 5th editions of the APA Manual.
Therefore, it would not be helpful for you to purchase or use
an older edition.
This can be a complicated issue. For instance, many students incorrectly
believe that, if a work is available on the free Web or if they
cannot identify the author of a work, they do not need to cite it.
Other students think that they can weave together information from
several different sources, sometimes using phrases from those sources,
and that they do not need to cite that information. In both cases,
these students are incorrect. Using another person's material under
any circumstances without citing it is plagiarism. For more information
on plagiarism, see the Online Guide to Writing and Research Chapter
5: Academic Integrity and Documentation. When in doubt, you
can seldom go wrong by citing the source.
In general, you must cite any information from another source except
for information that can be considered "common knowledge." In your
papers, you should provide citations for the following:
- opinions, theories, statements, beliefs, or ideas from any
source
- any information (facts, statistics, etc.) that is not common
knowledge
- direct quotations of written or spoken words from another source,
even if you use just phrases or partial statements
- paraphrases or summaries of written or spoken words from another
source, even if you use just phrases or partial statements. What
is the difference between a paraphrase and a summary? According
to UMUC's Online Guide to Writing and Research, in a paraphrase
you repeat "what someone else has said in your own words."
Your statement is usually either the same length or longer than
the original. In contrast, in a summary, you incorporate the ideas
you have read but condense the information so that it is briefer
than the original.

You will find the correct answers at the end of the exercise.
Help! I
can't find an example that fits the
material I need to cite. |
|
With as many examples as the Publication Manual
of the American Psychological Association provides, it doesn't
begin to cover all situations. How do you handle the citation if
the closest citation example you've found in the Manual has
only two authors and your article has four? The answer is
that citing is really more of an art than a science. You have to
begin with the standard citations the Manual provides,
find the similarities with your source, and then use these standard
citations and the rules in the Manual to create a citation
that you feel is most applicable to your resource. See below to
view an example of how to formulate the citation.
Example: You retrieve a transcript
of a television show from a Web site and note the following:
|
INFORMATION YOU FIND
Title of the broadcast:
Vietnam: A Television History: The Tet Offensive on The American
Experience;
Executive producer: Richard
Ellison
Broadcast date: November
4, 1983
Produced by: WGBH, Boston,
Accessed on: October
30, 2002
URL: http://www.pbs.org/wgbh/amex/vietnam/107ts.html.
|
|
CLOSEST CITATION EXAMPLE IN APA MANUAL
(TELEVISION BROADCAST)
Crystal, L. (Executive Producer). (1993,
October 11).The
MacNeil/Lehrer news hour (Television broadcast).
New York and Washington, D.C: Public Broadcasting
Service.
|
But there is no example for an online transcript
of a television show. How then will you format the citation? When
you study the above citation, you see some similarities with your
reference. You decide you will need:
- the producer's name
- the producer's title
- the date of the broadcast
- the program title
- the type of audiovisual media
- the production location
What additional information will you need? Since
you located the transcript online, you look in the Manual for
the correct way to format electronic resources and find the following:
| Standard format |
Examples |
|
Retrieved month day, year, from database name or URL
|
subscription database:
Retrieved June 10, 2002, from Academic Search Premier database.
Web site::
Retrieved June 10, 2002, from http://www.umuc.edu
|
Thus, for the electronic resource part, you decide
you need
- the date you accessed the transcript
- a URL or subscription database title
In addition, since this is only a transcript and not an actual
show you watched, you decide you need to indicate that your document
is a transcript.
Finally, you come up with the correct citation:
Ellison, R. (Executive Producer). (1983, November
4). The American
experience. Vietnam:
A television history: The Tet
offensive (Television Broadcast
Transcript). Boston: WGBH.
Retrieved October 30, 2002, from

It is important to think about citing when you
are doing research. For example, a photocopy of an article may not
include all the information you will need in order to cite it. Make certain that you have the full list
of authors, title of article, name of the journal, volume, issue
and pages. It will be much more difficult to obtain this information
afterwards.
Citing Web sites requires you to be even more careful
at the time you gather information since the Web site may change.
Citation information may be challenging to obtain; for example,
you may need to follow the URL to the site's homepage to determine
the author of the site. Be careful, because a site may be linked
by an organization not associated with it. In addition, be sure
to note the date that you accessed the Web site (or any electronic
resource) because you will need that information for the citation.
For example, assume you are doing a paper for an
education class on children who have trouble in school because they
cannot process what the teacher says to them. You find a useful
online site that would be perfect for your paper. Think ahead and
make certain that the page contains all the information you will
need to write your citation.. On the following screen, I've
circled some information you need.

But what is NIDCD and where is the date and publication number?
To find out more, you would scroll down and see the following information
at the bottom of the Web page.
You see that NIDCD are the initials of the government
agency (author): National Institute on Deafness and Other Communication
Disorders. You also note that the publication has a publication
number and date.
Now you have all the information you need to create
the citation below.
Citation:
National Institutes of Health, National Institute
on Deafness and Other
Communication Disorders. (2001, March). Auditory
processing disorder in children: What does it mean? (NIH
Pub. No. 01-4949). Retrieved October 25, 2002, from
http://www.nidcd.nih.gov/health/pubs_vsl/auditory.html
If the full name of NIDCD had not been available
on this page, you might have needed to click on the home button
or search the source of the URL (www.nidcd.nih.gov) for additional
information.
| How do I cite within the
paper? |
|
Within the text you need to identify
the sources briefly so that readers can tie them to more complete
information in the reference list at the end of the article. In
APA style you provide the last name of the author, the year of publication
and the page number if available in the text.
When citing electronic sources, you probably will not know on what
page the quote was found because you cannot see the original pagination
(unless the pages are PDF reproductions of the original article
in print). If the paragraphs are numbered in an electronic document,
use the symbol ¶ or the abbreviation para.
Example: (Smith, 1997, para. 12) or (Smith, 1997, ¶ 12)
You need to give in-text citations for any material you get from
another source, whether you quote it directly, summarize it, or
paraphrase it. There are different rules for formulating the citation
depending on how many authors there are and how you introduce or
insert the material into your text.
| Where should I put the
in-text citation? |
|
In your text you can cite the author and date before you introduce
the quote, summary, or paraphrase or write that information in parentheses
after an introductory word, such as study or research. The page
number (if available) comes after the cited material.
Use the following table to find details on how to cite in particular
situations.
|
One Author |
You can use either of these formats:
Friedman (1999) writes, "I feel about globalization a lot
like I feel about the dawn" (p. 37).
A study (Friedman, 1999) indicated that globalization
had the potential to be a new beginning (p. 37).
|
|
Two authors |
Multiple authors are cited with both last names if there
are only two. You can use either of these formats:
Example:
Frank and Jones (2001) stressed that schools need all-day
kindergarten. [electronic source so there is no page number]
or
The study (Frank & Jones, 2001) stressed...
|
|
Multiple authors |
For more authors (3-5), cite all authors the first time and
later include only the first author followed by et al. (and
the year if it is the first citation of the reference within
a paragraph.)
Example:
Turner, Allen, and Brown (2002) theorized that even
isolated economies welcome globalization (p. 166).
First use.
Thereafter, use et al. and omit date. Ex. Turner et al.
|
| Corporate or government agency as author |
For the first citation give the complete name of the corporation,
association, or government agency followed by an acronym in
brackets. If you refer to the source a second time, use only
the acronym followed by the date.
Example:
The study (United States Environmental Protection Agency [USEPA],
2002) demonstrates that controlling automobile emissions will
reduce global warming. First use.
Subsequent citations: The study (USEPA, 2002)...
|
| No author (anonymous works) |
If no author is given, provide a short title in quotation
marks (for article or chapter titles) or in italics (for book
titles).
Examples:
You can use either of these formats.
The study ("Nuclear Weapons Testing," 2002), indicated
that "environmental radioactivity from the testing of
nuclear weapons diminished after the major nuclear powers
declared a moratorium on atmospheric testing in 1963. "
Electronic article, no page number.
The book Vietnam War Statistics (1984) demonstrated...
|
| Two or more works by the same author |
These will be differentiated by year of publication; if the
year of publication is the same for several of an author's
works, add an a, b, c, etc. in alphabetical order by the title.
Example:
One study (Jones, 2002) showed the effect of ...
Another study (Jones, 1999) showed a different aspect.
You use two works by Jones published in 2002: 1. Good
Management Techniques and 2. Better Workplace Communication.
In your citation the first work becomes 2002b, and the second,
2002a because "Good" follows "Better"
in alphabetical order.
Example:
One study (Jones, 2002b) showed the effect of...
Another study (Jones, 2002a) showed a different aspect.
|
Interviews, telephone conversations, letters, etc. |
These are cited as personal communications. Since a person
researching your references can't obtain them, they are not
listed in the reference list. Provide an in-text citation
only. Give both the initials and the surname of the information
provider and the date of the interview, letter, etc. You can
use either of these formats.
Example:
Each day in the prison camp... (J. Morgan, personal
communication, June 3, 1984).
J. Morgan (personal communication, June 3, 1984) described...
|
Directly incorporated quotes, summaries or paraphrases |
If you do not use an introductory phrase but incorporate
the material directly into your text, the citation comes directly
after the quotation, summary, or paraphrased passage even
if it is in the middle of a sentence. If an entire paragraph
is a paraphrase of a single work, the citation comes at the
end of the paragraph. The rules for citing different types
of authors are the same as above.
Examples:
He stated, "I feel about globalization a lot
like I feel about the dawn" (Friedman, 1999, p. 37).
Even some of the most isolated economies, such as Mongolia
and Albania, have declared that they would welcome foreign
direct investment (Turner, Allen, & Brown, 2002, p. 166).
Although "people on diets alternate between gaining
and losing weight" (Peters, 2000), there is no definitive
evidence that shows that diets help overweight adults.
|
Combining information from several sources |
If you combine similar information from several articles
by different authors in a sentence or paragraph, you can combine
the citations in parentheses. Give the surname of the author(s)
and order the citations alphabetically as they appear in the
reference list.
Example:
Several studies (Jones, 1968; King & Baker, 1980; Morgan,
1972) explain the folly of President's Johnson's actions in
making a decision about whether or not to pull out of the
Vietnam War.
If you have different sentences, each of which contain information
from a different source, give citations for each different
source.
Example:
Johnson's mistrust of military men led to widespread deception
about the Vietnam War (McMaster, 1997, p. 44). Curtis (1997)
asserts that the situation deteriorated rapidly in Vietnam,
and Johnson couldn't decide whether or not to pull out. Johnson
denied that the war was his war. "It was 'America's war,'
he insisted," (Herring, 1997), but in the eyes of the
American people, it became his war.

The reference list is the bibliography at the end
of your paper where you tell the reader how to find the sources
to which you referred in the paper. The sources on the reference
list must match the sources in your in-text citations.
Together we'll go through creating a citation using
four examples. We've focused mainly on electronic resources, and
we've selected examples from formats that we think you will encounter
most often in your research at UMUC:
1. an article you found in one of the library's
more than 100 databases.
2. an article received electronically through DocumentExpress
or that you photocopied from a print library collection.
3. a chapter from a book. This selection is from an e-book but
an example for a print book would be the same except that the
last part of the citation, indicating when and where the e-book
was retrieved, would be omitted.
4. a Web site located on the free Web.
Obviously each of these categories has many permutations,
and there are other types of material you may need to cite as well.
For example, you may use information from government documents,
proceedings, videos, etc. Consult the
VAIL Citation Examples: APA and MLA Styles or Citing
Electronic Resources - APA and MLA styles for information
on how to cite in these less common situations. If you don't find
what you need there, additional examples are available in the Publication
Manual of the American Psychological Association, 5th edition.
Some General Tips
to Keep in Mind
When using APA style, remember to:
- type the first line of the citation at the left margin; all
other lines should be indented five spaces (use a hanging indent).
- double-space the entire reference list. Alternately, you can
single space the references and double space between references.
- italicize the title of a book or a journal, regardless of whether
it is in print or available electronically.
- alphabetize entries letter by letter in your reference list
at the end of your paper.
- use the author's first initial, never the entire first name.
- think of an electronic source as having two parts. Format the
first part as though it were a print source and then add the subscription
database or Web page information with the date you accessed it.
| Example 1: Article

library database |
|
The first screen shows a citation found in Business Source Premier
on May 3, 2003. The important elements you will need for the citation
have been circled. Below that you will find a blank template for
a citation and an example of what the citation would look like when
it is filled in using the information in the record.

| Example 2: Article
received electronically through DocumentExpress or found in
print |
|
This is an example of the first page of an article
that might have been sent to you electronically in PDF format after
you requested it through DocumentExpress. However, the principles
for citing would be similar if you had photocopied the article yourself.
Therefore, you will cite it as a print source and not as an electronic
source.
Not all articles supply this much information about the journal,
volume and pages in the header. Information and Library Services
sends you a copy of your request as well as the article so you will
have access to complete information for citing. If you are copying
an article yourself, make certain that you have all the information
you will need to cite the article. The elements you will need for
the citation have been circled.

|
This example was taken from an e-book available in NetLibrary and
retrieved on Sept. 25, 2002. The first screen shows the information
retrieved when you key in the title of the book. The second screen
shows what you would see when you select the chapter you wish to
view. You can't see the pages of the chapter on the screen excerpts
provided below but they are 37- 60. As mentioned earlier if this
were a print book instead of an e-book, you would cite it the same
way but omit the last part of the reference which indicates when
and where the material was retrieved.
Using an APA style citation example as a template,
you would fill in the information as shown below.

Not all Web sites provide as much information as this one which
was accessed on October 29, 2002. Don't panic! In composing your
citation, you are only expected to include as much of the required
information as you can find. Please note that on this example
you see only the author, title and URL.

To find out more, you would click on the Contents button on the

Are there any software
programs that could help me?
Citing can be time consuming. As mentioned in Module
1, there are commercial programs that can format your citations.
Some, like ProCite and EndNote, cost hundreds of dollars and allow
you to convert from one citation style to another. They can be useful
if you submit articles to multiple publications.
For many students, a relatively inexpensive software
program specializing in one style is adequate to meet most needs.
Information and Library Services (ILS) has created a list
of some software programs in which you may be interested. They
can be very helpful in determining the order of elements and assisting
you with the placing of punctuation. However, just like the grammar
and spelling checkers in word processing software, you cannot rely
on them too heavily. Even using software, you will need to
be able to identify the parts of a citation (author, title, publisher,
etc.). If you do not put the data into the software template correctly, the
resulting citation will be inaccurate. In addition, you need
to be familiar with APA rules in order to evaluate the software's
formatting and ensure its accuracy and applicability for your citations.
We hope that this tutorial will help you to cite
correctly either with or without the use of software programs. For
more information, consider the following resources.
If you have additional questions, please contact the Information and Library Services
staff for assistance.
