how to use citations in a research paper

Students often had difficulty using APA style, especially when it was their first time citing sources. This difficulty could be attributed to the fact that many students failed to purchase a style manual or to ask their teacher for help. (p. 199)

Summary or paraphrase

If you are paraphrasing an idea from another work, you only have to make reference to the author and year of publication in your in-text reference, but APA guidelines encourage you to also provide the page number (although it is not required).

According to Jones (1998), APA style is a difficult citation format for first-time learners.

What is a Citation?

A citation identifies for the reader the original source for an idea, information, or image that is referred to in a work.

From: Lemieux Library, University of Seattle

Why Should You Cite?

Quoting Are you quoting two or more consecutive words from a source? Then the original source should be cited and the words or phrase placed in quotes.

Paraphrasing If an idea or information comes from another source, even if you put it in your own words , you still need to credit the source. General vs. Unfamiliar Knowledge You do not need to cite material which is accepted common knowledge. If in doubt whether your information is common knowledge or not, cite it. Formats We usually think of books and articles. However, if you use material from web sites, films, music, graphs, tables, etc. you'll also need to cite these as well.

Plagiarism is presenting the words or ideas of someone else as your own without proper acknowledgment of the source. When you work on a research paper and use supporting material from works by others, it's okay to quote people and use their ideas, but you do need to correctly credit them. Even when you summarize or paraphrase information found in books, articles, or Web pages, you must acknowledge the original author.

How To Write a Research Paper

Why are citations important?

Apa citations.

Good research projects combine data from a variety of sources and carefully document the sources of information and ideas. Research documentation usually appears in two parts: short in-text citations occurring within the actual paper and a longer, complete list of works at the end of the paper called a bibliography, reference list, or works cited page.

Besides giving credit to the source of information or ideas, there are other great reasons to cite in your research project:

Note: a hyperlink or URL included in the text is not the same as a citation. Ex: "Higher gas prices are on the way (cnn.com/specialreport)." URLs in the text, while common on the internet, are not considered a correct form of scholarly citation.

APA is the most commonly used to cite sources for health sciences and social sciences fields. This guide, revised according to the 7th edition of the APA manual, offers examples for in-text citations, endnotes/footnotes, and your reference list or bibliography page.

Why should I cite my sources?

To see examples of citation examples for multiple source types , see the handout APA Quick Sheet .

APA Paper Format — the Basics

Papers constructed according to APA guidelines generally include the following elements:

In most cases, each of these elements will begin on a separate page, and it is important to note that not all academic papers will include all of these elements . Watch this short video from Excelsior OWL for set-by-step instructions on formatting an APA paper.

In-text references

How you cite a working within your document varies depending on your writing style, whether you are quoting your source directly, and the type of source you are quoting.

In APA format, follow the author, date method of in-text citation. This means that the author's last name and the year of publication for the source should appear in the text, e.g., (Jones, 1998), and a complete reference should appear in the reference list at the end of the paper.

If you are referring to an idea from another work but not directly quoting the material, or making reference to an entire book, article or other work, you only have to make reference to the author and year of publication in your in-text reference.

Here are some examples of in-text citations:

Short quotations

If you are directly quoting from a work, include the author, year of publication, and the page number for the reference (preceded by "p."). Introduce the quotation with a signal phrase that includes the author's last name followed by the date of publication in parentheses.

According to Jones (1998), "Students often had difficulty using APA style, especially when it was their first time" (p. 199). Jones (1998) found "students often had difficulty using APA style" (p. 199); what implications does this have for teachers? If the author is not named in a signal phrase, place the author's last name, the year of publication, and the page number in parentheses after the quotation. She stated, "Students often had difficulty using APA style," (Jones, 1998, p. 199), but she did not offer an explanation as to why.

Long quotations

Direct quotations longer than 40 words should be in a free-standing block of typewritten lines, and omit quotation marks. Start the quotation on a new line, indented five spaces from the left margin. Type the entire quotation on the new margin, and indent the first line of any subsequent paragraph within the quotation five spaces from the new margin. Maintain double-spacing throughout. The parenthetical citation should come after the closing punctuation mark.

Jones's (1998) study found the following:

Students often had difficulty using APA style, especially when it was their first time citing sources. (p. 199)

Summary or Paraphrase

When paraphrasing, make reference to the author and year of publication in your in-text reference, but APA guidelines encourage you to also provide the page number (not required.)

According to Jones (1998), APA style is a difficult citation format for first-time learners. APA style is a difficult citation format for first-time learners (Jones, 1998, p. 199).

Citing an Author or Authors

Two Authors: Name both authors in the signal phrase or in the parentheses each time you cite the work. Use the word "and" between the authors' names within the text and use the ampersand in the parentheses.

Three to Five Authors: List all the authors in the signal phrase or in parentheses the first time you cite the source.

In subsequent citations, only use the first author's last name followed by "et al." in the signal phrase or in parentheses.

Six or More Authors: Use the first author's name followed by et al. in the signal phrase or in parentheses.

Unknown Author: If the work does not have an author, cite the source by its title in the signal phrase or use the first word or two in the parentheses. Titles of books and reports are italicized or underlined; titles of articles and chapters are in quotation marks.

Organization as an Author: If the author is an organization or a government agency, mention the organization in the signal phrase or in the parenthetical citation the first time you cite the source.

If the organization has a well-known abbreviation, include the abbreviation in brackets the first time the source is cited and then use only the abbreviation in later citations.

Two or More Works in the Same Parentheses: When your parenthetical citation includes two or more works, order them the same way they appear in the reference list, separated by a semi-colon.

Personal Communication: For interviews, letters, e-mails, and other person-to-person communication, cite the communicator's name, the fact that it was personal communication, and the date of the communication. Do not include personal communication in the reference list.

Citing Indirect Sources

If you use a source that was cited in another source, name the original source in your signal phrase. List the secondary source in your reference list and include the secondary source in the parentheses.

Note: When citing material in parentheses, set off the citation with a comma, as above.

Sources Without Page Numbers

When an electronic source lacks page numbers, you should try to include information that will help readers find the passage being cited. When an electronic document has numbered paragraphs, use the ¶ symbol, or the abbreviation "para." followed by the paragraph number (Hall, 2001, ¶ 5) or (Hall, 2001, para. 5). If the paragraphs are not numbered and the document includes headings, provide the appropriate heading and specify the paragraph under that heading. Note that in some electronic sources, like Web pages, people can use the Find function in their browser to locate any passages you cite.

What Is A Citation?

When to cite.

A citation is a reference to the source of information used in your research. Any time you directly quote, paraphrase or summarize the essential elements of someone else's idea in your work, an in-text citation should follow. An in-text citation is a brief notation within the text of your paper or presentation which refers the reader to a fuller notation, or end-of-paper citation , that provides all necessary details about that source of information. Direct quotations should be surrounded by quotations marks and are generally used when the idea you want to capture is best expressed by the source. Paraphrasing and summarizing involve rewording an essential idea from someone else's work, usually to either condense the point or to make it better fit your writing style. You do not have to cite your own ideas, unless they have been published. And you do not have to cite common knowledge , or information that most people in your audience would know without having to look it up.

In-Text Citations

In-text citations alert the reader to an idea from an outside source.

Parenthetical Notes

In MLA and APA styles, in-text citations usually appear as parenthetical notes (sometimes called parenthetical documentation ). They are called parenthetical notes because brief information about the source, usually the author's name, year of publication, and page number, is enclosed in parentheses as follows:

MLA style: (Smith 263)

APA style: (Smith, 2013, p. 263)

Parenthetical notes are inserted into the text of the paper at the end of a sentence or paragraph:>

Example of a parenthetical in-text citation.

In MLA and APA styles, in-text citations are associated with end-of-paper citations that provide full details about an information source. Note: Different source types and situations require different information within the parentheses. Refer to a style guide for the style you are using for details.

Note Numbers

In Chicago and CSE styles, in-text citations usually appear as superscript numerals, or note numbers , as follows:

how to use citations in a research paper

These note numbers are associated with full citations that can appear as footnotes (bottom of page), endnotes (end of chapter or paper), or lists of cited references at the end of the paper.

End-of-Paper Citations

End-of-paper citations, as well as footnotes and endnotes, include full details about a source of information. Citations contain different pieces of identifying information about your source depending on what type of source it is. In academic research, your sources will most commonly be articles from scholarly journals, and the citation for an article typically includes:

There are many other types of sources you might use, including books, book chapters, films, song lyrics, musical scores, interviews, e-mails, blog entries, art works, lectures, websites and more. To determine which details are required for a citation for a particular source type, find that source type within the style guide for the citation style you are using. At the end of your research paper, full citations should be listed in order according to the citation style you are using:

Citations In Library Databases

When you search the library's databases for articles or e-books, the list of search results you see is actually a list of full citations. Instead of being formatted according to MLA, APA, CSE, or Chicago style, these citations are formatted according to the database vendor's style. It is up to you to take the source information you find in a library database (or elsewhere) and format it according to the citation style you are using.

Organizing Academic Research Papers: 11. Citing Sources

A citation is a reference to a published or unpublished source that you consulted and obtained information from while writing your research paper. The way in which you document your sources depends on the writing style manual your professor wants you to use for the class [e.g., APA, MLA, Chicago, Turabian, etc.]. Note that some disciplines have their own citation method [e.g., law].

Importance of a Citing your Sources

Citations show your readers where you obtained your material, provides a means of critiquing your study, and offers the opportunity to obtain additional information about the research problem under investigation.

Properly citing the works of others is important because:

In any academic writing, you are required to identify for your reader which ideas, facts, theories, concepts, etc., are yours and which are derived from the research and thoughts of others. Whether you summarize, paraphrase, or use direct quotes, if it's not your original idea, the source needs to be acknowledged. The only exception to this rule is information that is considered to be common knowledge [e.g., George Washington was the first president of the United States]. If in doubt regarding whether something is common knowledge, take the safe route and cite it, or ask your professor for clarification.

Citing Information . The Writing Center. University of North Carolina; Referencing More Effectively. Academic Skills Centre. University of Canberra.

Structure and Writing Style

Referencing your sources means systematically showing what information or ideas you are quoting or paraphrasing from another author’s work, and where they come from . You must cite research in order to do research, but at the same time, you must indicate what are your original thoughts and ideas and what are the thoughts and ideas of others. Systems used to reference the sources you've used vary among different fields of study. However, always speak with your professor about what writing style for citing sources should be used for the class because it is important to fully understand the citation style to be used in your paper, and to apply it consistently.

Compiled by Timothy T. Allen , revised 2000. This paper greatly expands upon a handout originally prepared by an unknown author for distribution to students in introductory earth science courses at Dartmouth College. The work is presented here without copyright, although acknowledgement is (of course) appreciated. This document is also available in in Adobe Acrobat Format

Introduction

It is important to properly and appropriately cite references in scientific research papers in order to acknowledge your sources and give credit where credit is due. Science moves forward only by building upon the work of others. There are, however, other reasons for citing references in scientific research papers. Citations to appropriate sources show that you've done your homework and are aware of the background and context into which your work fits, and they help lend validity to your arguments. Reference citations also provide avenues for interested readers to follow up on aspects of your work -- they help weave the web of science. You may wish to include citations for sources that add relevant information to your own work, or that present alternate views. The reference citation style described here is a version of the "Author, Date" scientific style, adapted from Hansen (1991) and the Council of Biology Editors (1994). Harnack & Kleppinger (2000) have adapted "CBE style" to cite and document online sources . When to Cite References in Scientific Research Papers You should acknowledge a source any time (and every time) you use a fact or an idea that you obtained from that source. Thus, clearly, you need to cite sources for all direct quotations. But you also need to cite sources from which you paraphrase or summarize facts or ideas -- whether you've put the fact or idea into your own words or not, you got the fact or idea from somebody else and you need to give them proper acknowledgement (even if an idea might be considered "common knowledge," but you didn't know it until you found it in a particular source).

If you have more than one source by the same author published in the same year, distinguish them both in the in-text citation and in the reference list, by appending the letters a, b, c... to the year, in the order in which the different references appear in your paper. (For example: Allen 1996a, 1996b.)

If your source of information has no individual identifiable author, use the name of the organization to which the work can be attributed in place of the author's name:

For internet sources without any identifiable author or date, simply use the URL address as the in-text citation:

As New England is located at the convergence of several distinct storm tracks ( http://www.mountwashington.org/mtw_mtn.htm ), we expect to find clear differences in isotopic composition among seasons and potentially among different rain storm events (Fig. 1).

Such a source would be omitted from your References Cited or Bibliography section.

A Beginner’s Guide to Citations, References and Bibliography in Research Papers

As an academician, terms such as citations, references and bibliography might be a part of almost every work-related conversation in your daily life. However, many researchers, especially during the early stages of their academic career, may find it hard to differentiate between citations, references and bibliography in research papers and often find it confusing to implement their usage. If you are amongst them, this article will provide you with some respite. Let us start by first understanding the individual terms better.

Citation in research papers: A citation appears in the main text of the paper. It is a way of giving credit to the information that you have specifically mentioned in your research paper by leading the reader to the original source of information. You will need to use citation in research papers whenever you are using information to elaborate a particular concept in the paper, either in the introduction or discussion sections or as a way to support your research findings in the results section.

Reference in research papers: A reference is a detailed description of the source of information that you want to give credit to via a citation. The references in research papers are usually in the form of a list at the end of the paper. The essential difference between citations and references is that citations lead a reader to the source of information, while references provide the reader with detailed information regarding that particular source.

Bibliography in research papers:

A bibliography in research paper is a list of sources that appears at the end of a research paper or an article, and contains information that may or may not be directly mentioned in the research paper. The difference between reference and bibliography in research is that an individual source in the list of references can be linked to an in-text citation, while an individual source in the bibliography may not necessarily be linked to an in-text citation.

It’s understandable how these terms may often be used interchangeably as they are serve the same purpose – namely to give intellectual and creative credit to an original idea that is elaborated in depth in a research paper. One of the easiest ways to understand when to use an in-text citation in research papers, is to check whether the information is an ongoing work of research or if it has been proven to be a ‘fact’ through reproducibility. If the information is a proven fact, you need not specifically add the original source to the list of references but can instead choose to mention it in your bibliography. For instance, if you use a statement such as “The effects of global warming and climate changes on the deterioration of environment have been described in depth”, you need not use an in-text citation, but can choose to mention key sources in the bibliography section. An example of a citation in a research paper would be if you intend to elaborate on the impact of climate change in a particular population and/or a specific geographical location. In this case, you will need to add an in-text citation and mention the correct source in the list of references.

Now that you have understood the basic similarities and differences in these terms, you should also know that every journal follows a particular style and format for these elements. So when working out how to write citations and add references in research papers, be mindful of using the preferred style of your target journal before you submit your research document.

APA In-Text Citations for Research Writing

Why Use In-Text Citations?

When writing a journal article, literature review, convention paper, or any other academic document, authors must include in-text citations whenever they refer to, summarize, paraphrase, or quote from another source. In addition, every time a work is cited within a paper (in APA style, a parenthetical citation), a corresponding entry must be included in the reference list.

How to Cite a Research Paper Using In-Text Citations

The rationale behind citing other people’s publications in your own manuscript is that you want to avoid intellectual dishonesty by giving credit to whoever reported a finding first or invented a specific technique. This is not only an ethical question, as being “sloppy” with your sources can easily be considered plagiarism (and even self-plagiarism , if you fail to refer to your own work), which can have legal consequences and damage your reputation.

General rules for what information should be provided when citing sources in a research paper vary across fields and depend on the type of source (e.g., books, journal articles, patents, conference proceedings, websites, etc.). We are not going into such differences here but will focus on the correct way of referencing other people’s research in your own paper according to one of the most common styles used to cite sources within the social sciences and in several other academic disciplines , that is, APA (American Psychological Association) style .

In research papers, in-text citations are most commonly used in the Introduction and Discussion Results sections. The following guidelines and examples are taken from the APA Publication Manual, 6th edition, 2nd printing , which details rules and application of APA style in research papers, including in-text citations, endnotes/footnotes, and references. For more information, consult the APA Style Manual website .

This resource provides detailed guidelines for citing sources in your paper and includes examples of in-text citations for reference by research authors. Before submitting your manuscript to a journal or publisher, be sure to use our free APA citation generator for your references and in-text citations.

APA Citation Rules: The Basics

Order and structure of in-text citation content.

When using APA format, follow the “author-date” method of in-text citation. Write the author’s last name and publication year for the source in parentheses and separate these pieces of information with a comma.

When referring to external work or referencing an entire work but not directly quoting the material, you only need to make a reference to the author and year of publication and not the page number in your citation.

The results of the first enzyme study (Chen et al., 2014) revealed several relationships.

If you mention the name of the author of the work in the sentence or earlier in the paragraph, you only need to include the year of publication in the citation.

Chen (2014) discusses several relationships revealed in this study.

Verb tense used in referring to other works

APA style requires authors to use past tense or present perfect tense (NOT present tense) when using signal phrases to refer to or discuss previous research (have a look at this article for more details on the correct tenses for different parts of a research paper ).

Radnitz (1995) found… / Radnitz (1995) has found…

Placement of in-text citations in the sentence (no quotation)

When referring to a specific work or works, place the citation (publication date only) directly after the author of the study referenced.

Klinge and Rogers (2010) found that mirroring is instrumental in developments of performative gender roles.

When giving information that reflects the results or implications of previous work, place the citation (author and publication date) at the end of the sentence.

Mirroring has been found to be instrumental in the development of performative gender roles (Klinge and Rogers, 2010).

Capitalization

Always capitalize author names and initials in in-text citations.

(r. kazinsky, 2014) (R. Kazinsky, 2014)

In-Text Citation Rules for Short Quotations

When quoting directly from a work, include the author, publication year, and page number of the reference (preceded by “p.”).

Method 1 : Introduce the quotation with a signal phrase that includes the author’s last name; the publication year will follow in parentheses. Include the page number in parentheses at the end of the quoted text. Note that the quotation marks surround the text only, and not the parenthetical citation.

According to Khan (1976), “Graduate students tend to apply more diverse methods during their first two years of research” (p. 45). Khan (1976) noted that “graduate students tend to apply more diverse methods during their first two years of research” (p. 45), a fact that has profound implications for research departments.

Method 2 : If the author is absent in the signal phrase, include the author’s last name, the publication year, and the page number together in parentheses after the quoted text.

Researchers noted that “graduate students tend to apply more diverse methods during their first two years of research” (Khan, 1976, p. 45), but they did not offer a suggestion as to the cause.

In-text Citation Rules for Long Quotations

Long direct quotations are those with at least 40 words of quoted text in a row. Long quotes should be placed in a separate block of lines without quotation marks, similar to creating a new paragraph. Begin the quotation on a new line and indent 0.5in/1.27cm from the left margin. Type the entire quotation within these new margins using double-spacing. Include the parenthetical citation after the final punctuation mark.

Khan’s (1976) study found the following: Graduate students tend to apply more diverse methods during their first two years of research, especially when conducting research in teams of three or fewer with no senior researchers present. This tendency could be attributed to either a misunderstanding of correct methodology or to a feeling of freedom to explore different approaches that the researchers have yet to employ. (p. 45)

Summarizing and Paraphrasing Other Works

When paraphrasing another work , you only need to cite the author and year of publication in your in-text citation. It may be a good idea to include the page number as well if the paraphrased information is located on a specific page of the original text. APA guidelines encourage this inclusion but do not require it.

According to Khan (1976), new researchers tend to use more diverse methodologies. New researchers tend to use more diverse methodologies (Khan, 1976, p. 45).

Common Signal Phrases for Introducing External Works

Citing Works by Multiple Authors/Editors

When making an in-text citation of works by multiple authors, there are specific rules to follow depending on the number of authors of a publication and the number of times you cite the same works.

Citing Multiple Works in One In-text Citation

When citing more than one source in the same in-text citation, list all sources in the standard way and separate them with a semi-colon. List the sources alphabetically (by author’s last name or by title if no author is given) in the order they appear in the reference list.

(Marsh, 1997; Johnson, 2002). (Kazinsky, 2017; “Three Different Roads,” 2013).

Citing Works by the Same Author with the Same Publication Year

When citing two or more sources with the same author and year of publication, assign lowercase letters directly after the year of publication (a, b, c) according to the alphabetical order of titles. You will use the same alphabetical designations in your in-text citations that you do in your reference list.

The incidence of West Nile virus in Florida increased between 2002 and 2004 (Dickens, 2014a). According to Dickens (2014b), “these viral infections were precipitated by record levels of rainfall around the peninsula” (p. 150).

Citing a Work Quoted in another Source

Work quoted or paraphrased in another text is called a “secondary source.” While in your reference list you must cite the primary source as well, in your in-text citation you will add the words “as cited in” followed by the secondary source. For example, if a review article by Franklin you are citing includes a useful quote by Adams that supports your paper, your in-text citation would look like this:

According to a study by Adams (as cited in Franklin, 2016), 25% of all US federal prisoners have been diagnosed with some form of social disorder. Adams (as cited in Franklin) contends that this statistic “reflects the dehumanizing conditions of most federal institutions” (p. 76).

Citing Web Pages

Entire website.

When citing an entire website (with no specific webpage or article given), simply provide the title and web address within the text of your paper. No citation is needed in the References.

The American Psychological Association includes detailed information on how to apply APA citation (http://www.apa.org).

Webpage with author(s)

A webpage with an individual author or authors should be cited in the same way as other texts, with the name or names written first, followed by the publication year.

There were 523 new cases reported in 2011 alone (Kristoff, 2012).

Webpage with a group author

Treat group authors as individual authors in in-text citations, but instead of the author’s last name, include the name of the group.

Claustrophobia afflicts one in five Britons (The Surrey Group, 2003).

Webpage with missing information

Even when some central information is missing from a website (e.g., no author, date, or webpage title), you may still cite it as a source if you use the correct formatting. For information on how to cite a website with missing information, visit the APA Style Blog post on Missing Pieces .

Citing social media sources
