How To Properly Cite Sources In A Research Paper

Term Paper: Format of Citations and References

1. Introduction

As you write your term papers, it will be important for you to document where you obtained the information cited in your report. Many of the references you use will come from published sources. Some may come from electronic sources such as the World Wide Web, Melvyl and Harvest databases available through the UC Davis library, CD references and the like, and some may come from interviews. An important component of your writing will be the effective use of reference material. This skill will serve you well in writing papers of all types, not just those required for classes.

For this class, we will be using the documentation style of the American Psychological Association (APA, 2001) modified with italics substituted for underlining. This format is very similar to that of the Modern Language Association, and these are the most commonly used styles for publishing in the social and natural sciences. The general form of citations in the body of the text is to include the author and date in parentheses (as above) and optionally include the page number(s) after the date. If the author's name was just mentioned in the text, it is not necessary to repeat it in the citation. The rules are described in more detail, with examples, in section 3.

2. Basic Guidelines

The purpose of the term paper in ECS 15 is for you to learn how to do effective research on a subject and then write it up clearly, showing where you got your information.

A research paper requires searching for information pertinent to a given subject, organizing it, and presenting it effectively in written form. Oral research reports are also useful, but this course does not cover them.

In the following sections, we will present the way that we want you to cite your references in the term paper for this course. The required format meets the accepted practices cited in Li and Crane (1993), a reference that is currently considered the best authority on citing electronic sources. This book in turn follows the basic format for the American Psychological Association (APA, 2001), which is a good format (though by no means the only acceptable one in technical publications). You may be required to use slightly different formats for other papers, such as papers submitted for publication to refereed journals, each of which typically have their own styles. Learning how to follow one such set of rules is a worthwhile exercise. You will therefore be expected to use the format set out below.

3. In-text Citation to References

When citing a reference from your reference list, please use the following conventions. Put in parentheses the author(s) last names, the year, and optionally the page number(s) separated by commas.

For one author, use the author's last name and year separated by a comma. For example: (Walters, 1994) or (Austin, 1996).

For two to five authors, use their last names separated by commas and with an ampersand "&" before the very last name in the list, then the year separated by a comma. For example: (Li & Crane, 1993) (Charniak, Riesbeck, McDermott & Meehan, 1994).

For more than five authors, use the first author's last name and "et al." For example: (Walters, et al., 1992).

For the date, use the year. If there are two references by the same author(s) for the same year, use letters after the year: (Walters, 1993b).

If there are specific page numbers for a citation, add them after the year (Walters, 1994, pp. 31-49).

If you include the author's name(s) in the text of a sentence in the paper, you may omit their names from the parentheses as follows: "Austin (1996) includes valuable references to ...." or "The examples given by Li and Crane (1993) on web addresses ...".

Do not use footnotes in this class for citations. You can use them for explanatory text, but not for references. Have the citation make it easy to find the reference in the "References" section. All references in that section should be complete enough for readers to obtain a copy for themselves.

4. Your List of References

Create a list of references, one for each item cited in the paper, in a section called "References". This section goes at the end of your paper. The references are to be alphabetized by the fist author's last name, or (if no author is listed) the organization or title. If you cite more than one paper by the same first author, sort them by year of publication, earliest year first. Do not use footnotes for citations.

Single-space the entries in your list of references. Start at the left margin for the first line of each bibliography entry. Each additional line of each entry should be indented a reasonable amount. Separate the entries with a blank line. Do not number the references. Doing so means you have to renumber all the references whenever you insert a new reference.

4.1. Author, Date, and Title

The general format for the author, title, and date in your reference list is as follows:

    Author. (date). Title. [the full reference, which follows, is discussed below]

The following explains these fields.

Author

First author's last name, followed by the initials. If there are two authors, separate their names with "and". For three or more authors, separate all but the last author's name with commas, and use "and" before the last author's name in the list. If published by an agency with no author given, list the name of the agency. End with a period. For example:

    Walters, R.F.

    Walters, R.F. and Reed, N.E.

    Walters, R.F., Bharat, S. R. and Austin, A.A.

    Charniak, E., Riesbeck, C., McDermott, D. and Meehan, J.

    National Bureau of Standards.

Date

Enclose the date in parentheses. Use a date sufficiently specific for the item. For example, give the year of publication for a book, the year and month of publication for a monthly magazine or journal, and the year, month, and day for a newspaper or daily periodical. End with a period. For example:

    (1995).

    (1992, October).

    (1995, August 30).

Title

If the title is that of an article, use the regular font; if it is the title of a book, italicize it. Capitalize only the first letter of the first word and proper nouns. If there is a subtitle, it too should begin with a capital letter. End with a period. For example, an article's title would look like:

    Computer-based systems integration.

and a book's title would look like:

    The abc's of MUMPS: An introduction for novice and intermediate programmers.

4.2. Journals, Magazines, and Newspapers

The following apply to citing the name and identifying information for journals, magazines, newspapers, and periodicals in general.

Title

When citing the name of a journal, magazine or newspaper, write the name in italics, with all words capitalized except for articles, prepositions and conjunctions.

Volume, number, and page numbers

Give the volume number in italics, followed by the issue number in parentheses (if there is an issue number), and the page number(s). For magazines, precede page numbers with "p." (if the article is on a single page) or "pp." (if the article is on multiple pages). For example:

    Communications of the ACM, 27(2), 141-195.

    Journal of Advertising Research, 32, 47-55.

    Time, 146, pp. 42-44.

Publisher and Location

Give the city and state (if in the United States), followed by a colon and the publisher name, followed by a period. For example:

    Englewood Cliffs NJ: Prentice-Hall.

    London: Edward Arnold

4.3. Interviews

If you choose to include any personal interviews, reference them with the person's name, their professional title and employer, and the date, time, and place of the interview. For example:

    Albert Einstein (1935, January 5), Professor of Theoretical Physics, Princeton University, 3:00pm, Princeton, NJ.

4.4. References Found in Electronic Form

Many resource materials are available through Melvyl and Harvest, which are the electronic access points for the UC Davis library. More are on CDROM, or on the Internet. These can serve as appropriate references for research reports and term papers. It is important, however, to acknowledge the sources of these documents, even though you may never have seen "hard copy" (printed versions) of the file(s) you wish to cite. This section describes how you are to cite references that you have obtained from electronic repositories.

The basic form of your reference will be similar to printed references, but you will need to add some important additional information: the type of medium used, and the material's availability.

In general, if you wish to cite an electronic file, you should include either the term "[Online]" or the term "[CDROM]" (enclosed in square brackets) before the closing period terminating the title of the work cited. If you are citing a part of a larger work, you should give the title, followed by a comma, the word "In" followed by the larger work, and then add "[Online]" or "[CDROM]" as appropriate, followed by a period.

Citing the availability of an electronic document should give the reader enough information to know where to locate the file and, if necessary, the specific portion of the file cited. Electronic documents can come from several types of locations:

    ftp: identify the ftp server, location (path), and file name

    Internet (e.g., world wide web): give the location and file name; the URL is sufficient

    mailing lists, newsgroups: identify the server, method of access, and file name; do not cite personal email

    databases (e.g., computer database in Melvyl): identify access method

In each case, you should give enough information to let the reader know how to access the information electronically. Generally, giving the site (Internet-style server name) on which the information resides, the name of the file, and the complete path (list of directories) showing how to get to it is sufficient.For example:

    [Online]. Available: email: listserv@ncsuvm.cc.ncsu.edu Message: Get POETICS TODAY.

    [Online] Available: FTP: ftp.bio.indiana.edu, Location: /usenet/bionet/neuroscience, File: 9512.newsm.

MLA In-Text Citations: The Basics

Summary:

MLA (Modern Language Association) style is most commonly used to write papers and cite sources within the liberal arts and humanities. This resource, updated to reflect the MLA Handbook (8th ed.), offers examples for the general format of MLA research papers, in-text citations, endnotes/footnotes, and the Works Cited page.

Guidelines for referring to the works of others in your text using MLA style are covered in chapter 6 of the MLA Handbook and in chapter 7 of the MLA Style Manual. Both books provide extensive examples, so it's a good idea to consult them if you want to become even more familiar with MLA guidelines or if you have a particular reference question.

Basic in-text citation rules

In MLA style, referring to the works of others in your text is done by using what is known as parenthetical citation. This method involves placing relevant source information in parentheses after a quote or a paraphrase.

General Guidelines

  • The source information required in a parenthetical citation depends (1.) upon the source medium (e.g. Print, Web, DVD) and (2.) upon the source’s entry on the Works Cited (bibliography) page.
  • Any source information that you provide in-text must correspond to the source information on the Works Cited page. More specifically, whatever signal word or phrase you provide to your readers in the text, must be the first thing that appears on the left-hand margin of the corresponding entry in the Works Cited List.

In-text citations: Author-page style

MLA format follows the author-page method of in-text citation. This means that the author's last name and the page number(s) from which the quotation or paraphrase is taken must appear in the text, and a complete reference should appear on your Works Cited page. The author's name may appear either in the sentence itself or in parentheses following the quotation or paraphrase, but the page number(s) should always appear in the parentheses, not in the text of your sentence. For example:

Wordsworth stated that Romantic poetry was marked by a "spontaneous overflow of powerful feelings" (263).

Romantic poetry is characterized by the "spontaneous overflow of powerful feelings" (Wordsworth 263).

Wordsworth extensively explored the role of emotion in the creative process (263).

Both citations in the examples above, (263) and (Wordsworth 263), tell readers that the information in the sentence can be located on page 263 of a work by an author named Wordsworth. If readers want more information about this source, they can turn to the Works Cited page, where, under the name of Wordsworth, they would find the following information:

Wordsworth, William. Lyrical Ballads. Oxford UP, 1967.

In-text citations for print sources with known author

For Print sources like books, magazines, scholarly journal articles, and newspapers, provide a signal word or phrase (usually the author’s last name) and a page number. If you provide the signal word/phrase in the sentence, you do not need to include it in the parenthetical citation.

Human beings have been described by Kenneth Burke as "symbol-using animals" (3).

Human beings have been described as "symbol-using animals" (Burke 3).

These examples must correspond to an entry that begins with Burke, which will be the first thing that appears on the left-hand margin of an entry in the Works Cited:

Burke, Kenneth. Language as Symbolic Action: Essays on Life, Literature, and Method. Berkeley: U of California P, 1966.

In-text citations for print sources by a corporate author

When a source has a corporate author, it is acceptable to use the name of the corporation followed by the page number for the in-text citation. You should also use abbreviations (e.g., nat'l for national) where appropriate, so as to avoid interrupting the flow of reading with overly long parenthetical citations.

In-text citations for print sources with no known author

When a source has no known author, use a shortened title of the work instead of an author name. Place the title in quotation marks if it's a short work (such as an article) or italicize it if it's a longer work (e.g. plays, books, television shows, entire Web sites) and provide a page number if it is available.

We see so many global warming hotspots in North America likely because this region has "more readily accessible climatic data and more comprehensive programs to monitor and study environmental change . . ." ("Impact of Global Warming").

In this example, since the reader does not know the author of the article, an abbreviated title of the article appears in the parenthetical citation which corresponds to the full name of the article which appears first at the left-hand margin of its respective entry in the Works Cited. Thus, the writer includes the title in quotation marks as the signal phrase in the parenthetical citation in order to lead the reader directly to the source on the Works Cited page. The Works Cited entry appears as follows:

"The Impact of Global Warming in North America." Global Warming: Early Signs. 1999. http://www.climatehotmap.org/. Accessed 23 Mar. 2009.

We'll learn how to make a Works Cited page in a bit, but right now it's important to know that parenthetical citations and Works Cited pages allow readers to know which sources you consulted in writing your essay, so that they can either verify your interpretation of the sources or use them in their own scholarly work.

Author-page citation for classic and literary works with multiple editions

Page numbers are always required, but additional citation information can help literary scholars, who may have a different edition of a classic work like Marx and Engels's The Communist Manifesto. In such cases, give the page number of your edition (making sure the edition is listed in your Works Cited page, of course) followed by a semicolon, and then the appropriate abbreviations for volume (vol.), book (bk.), part (pt.), chapter (ch.), section (sec.), or paragraph (par.). For example:

Marx and Engels described human history as marked by class struggles (79; ch. 1).

Citing authors with same last names

Sometimes more information is necessary to identify the source from which a quotation is taken. For instance, if two or more authors have the same last name, provide both authors' first initials (or even the authors' full name if different authors share initials) in your citation. For example:

Although some medical ethicists claim that cloning will lead to designer children (R. Miller 12), others note that the advantages for medical research outweigh this consideration (A. Miller 46).

Citing a work by multiple authors

For a source with two authors, list the authors’ last names in the text or in the parenthetical citation:

Best and Marcus argue that one should read a text for what it says on its surface, rather than looking for some hidden meaning (9).

The authors claim that surface reading looks at what is “evident, perceptible, apprehensible in texts” (Best and Marcus 9).

Corresponding works cited entry:

Best, David, and Sharon Marcus. “Surface Reading: An Introduction.” Representations, vol. 108, no. 1, Fall 2009, pp. 1-21. JSTOR, doi:10.1525/rep.2009.108.1.1

For a source with three or more authors, list only the first author’s last name, and replace the additional names with et al.

According to Franck et al., “Current agricultural policies in the U.S. are contributing to the poor health of Americans” (327).

The authors claim that one cause of obesity in the United States is government-funded farm subsidies (Franck et al. 327).

Corresponding works cited entry:

Franck, Caroline, et al. “Agricultural Subsidies and the American Obesity Epidemic.” American Journal of Preventative Medicine, vol. 45, no. 3, Sept. 2013, pp. 327-333.

Citing multiple works by the same author

If you cite more than one work by a particular author, include a shortened title for the particular work from which you are quoting to distinguish it from the others. Put short titles of books in italics and short titles of articles in quotation marks.

Citing two articles by the same author:

Lightenor has argued that computers are not useful tools for small children ("Too Soon" 38), though he has acknowledged elsewhere that early exposure to computer games does lead to better small motor skill development in a child's second and third year ("Hand-Eye Development" 17).

Citing two books by the same author:

Murray states that writing is "a process" that "varies with our thinking style" (Write to Learn 6). Additionally, Murray argues that the purpose of writing is to "carry ideas and information from the mind of one person into the mind of another" (A Writer Teaches Writing 3).

Additionally, if the author's name is not mentioned in the sentence, you would format your citation with the author's name followed by a comma, followed by a shortened title of the work, followed, when appropriate, by page numbers:

Visual studies, because it is such a new discipline, may be "too easy" (Elkins, "Visual Studies" 63).

Citing multivolume works

If you cite from different volumes of a multivolume work, always include the volume number followed by a colon. Put a space after the colon, then provide the page number(s). (If you only cite from one volume, provide only the page number in parentheses.)

. . . as Quintilian wrote in Institutio Oratoria (1: 14-17).

Citing the Bible

In your first parenthetical citation, you want to make clear which Bible you're using (and underline or italicize the title), as each version varies in its translation, followed by book (do not italicize or underline), chapter and verse. For example:

Ezekiel saw "what seemed to be four living creatures," each with faces of a man, a lion, an ox, and an eagle (New Jerusalem Bible, Ezek. 1.5-10).

If future references employ the same edition of the Bible you’re using, list only the book, chapter, and verse in the parenthetical citation.

Citing indirect sources

Sometimes you may have to use an indirect source. An indirect source is a source cited in another source. For such indirect quotations, use "qtd. in" to indicate the source you actually consulted. For example:

Ravitch argues that high schools are pressured to act as "social service centers, and they don't do that well" (qtd. in Weisman 259).

Note that, in most cases, a responsible researcher will attempt to find the original source, rather than citing an indirect source.

Citing non-print or sources from the Internet

With more and more scholarly work being posted on the Internet, you may have to cite research you have completed in virtual environments. While many sources on the Internet should not be used for scholarly work (reference the OWL's Evaluating Sources of Information resource), some Web sources are perfectly acceptable for research. When creating in-text citations for electronic, film, or Internet sources, remember that your citation must reference the source in your Works Cited.

Sometimes writers are confused with how to craft parenthetical citations for electronic sources because of the absence of page numbers, but often, these sorts of entries do not require any sort of parenthetical citation at all. For electronic and Internet sources, follow the following guidelines:

  • Include in the text the first item that appears in the Work Cited entry that corresponds to the citation (e.g. author name, article name, website name, film name).
  • You do not need to give paragraph numbers or page numbers based on your Web browser’s print preview function.
  • Unless you must list the Web site name in the signal phrase in order to get the reader to the appropriate entry, do not include URLs in-text. Only provide partial URLs such as when the name of the site includes, for example, a domain name, like CNN.com or Forbes.com as opposed to writing out http://www.cnn.com or http://www.forbes.com.

Miscellaneous non-print sources

Werner Herzog's Fitzcarraldo stars Herzog's long-time film partner, Klaus Kinski. During the shooting of Fitzcarraldo, Herzog and Kinski were often at odds, but their explosive relationship fostered a memorable and influential film.

During the presentation, Jane Yates stated that invention and pre-writing are areas of rhetoric that need more attention.

In the two examples above “Herzog” from the first entry and “Yates” from the second lead the reader to the first item each citation’s respective entry on the Works Cited page:

Herzog, Werner, dir. Fitzcarraldo. Perf. Klaus Kinski. Filmverlag der Autoren, 1982.

Yates, Jane. "Invention in Rhetoric and Composition." Gaps Addressed: Future Work in Rhetoric and Composition, CCCC, Palmer House Hilton, 2002.

Electronic sources

One online film critic stated that Fitzcarraldo "has become notorious for its near-failure and many obstacles" (Taylor, “Fitzcarraldo”).

The Purdue OWL is accessed by millions of users every year. Its "MLA Formatting and Style Guide" is one of the most popular resources (Russell et al.).

In the first example, the writer has chosen not to include the author name in-text; however, two entries from the same author appear in the Works Cited. Thus, the writer includes both the author’s last name and the article title in the parenthetical citation in order to lead the reader to the appropriate entry on the Works Cited page (see below). In the second example, “Russell et al.” in the parenthetical citation gives the reader an author name followed by the abbreviation “et al.,” meaning, “and others,” for the article “MLA Formatting and Style Guide.” Both corresponding Works Cited entries are as follows:

Taylor, Rumsey. "Fitzcarraldo." Slant, 13 Jun. 2003, www.slantmagazine.com/film/review/fitzcarraldo/.

Russell, Tony, et al. "MLA Formatting and Style Guide." The Purdue OWL, 2 Aug. 2016, owl.english.purdue.edu/owl/resource/747/01/.

Multiple citations

To cite multiple sources in the same parenthetical reference, separate the citations by a semi-colon:

. . . as has been discussed elsewhere (Burke 3; Dewey 21).

Time-based media sources

When creating in-text citations for media that has a runtime, such as a movie or podcast, include the range of hours, minutes and seconds you plan to reference, like so (00:02:15-00:02:35).

When a citation is not needed

Common sense and ethics should determine your need for documenting sources. You do not need to give sources for familiar proverbs, well-known quotations or common knowledge. Remember, this is a rhetorical choice, based on audience. If you're writing for an expert audience of a scholarly journal, for example, they'll have different expectations of what constitutes common knowledge.
