Citing Facts In Research Paper

Writing a research paper is an important skill you need to learn. In order to do a paper properly you need to keep a few things in mind which will be outlined below. The most important thing is to be complete, be consistent and be thorough. Remember, the process is the important part. Before we begin, keep the following terms in mind:

Plagiarism: This is what you want to avoid. Plagiarism means using someone else's work and claiming it as your own. In reality it is a crime. Plagiarism can occur on purpose as well as by accident, either way it is wrong and must be avoided. If you plagiarize by accident the same penalties apply. The way we avoid plagiarism is by citing sources. After the paper is written and the sources have been cited then we must create a works citedpage. If the proper format for citing sources and the works cited page is followed then plagiarism can be avoided.

Citing Sources: Most high schools use the MLA (Modern Language Association) format. Check with your teacher to see if this format is acceptable in your school. Sources in these formats use the in line citation format. What this means is that anytime you cite a source, whether it be a direct quote or a paraphrase you must then insert an in line citation into the text of the paper. Typically the in line citation would consist of the authors last name followed by the page number with the entire citation in brackets. Here is an example: (Winthrop 24) The sentence period comes after the citation. More is to follow on proper in line citation format after this introduction.

Paraphrase: A paraphrase is an important part of writing a paper. Simply put the paraphrase is when you read another authors work and put it into your own words. It is also considered paraphrasing when you use statistics and research from another source. This is the most common citation in a paper. Proper paraphrasing is an art. This does not mean changing a few words around. It means taking the authors ideas, summarizing them into your own words and then using them. Of course you must cite every paraphrase with an in line citation. Paraphrases are mostly used to summarize paragraphs and main themes. Paraphrases are also used to cite statistics and other information. YOU DO NOT USE QUOTATION MARKS WHEN PARAPHRASING. More is to follow on citing the paraphrase.

Direct Quote: A direct quote is when you use another persons words directly in your paper. Knowing when to use a direct quote is important. Do not quote everything you want to say. Most things should be paraphrased. Use a direct quote when you want the reader to read an important historical line or it is something someone said that is important. Use direct quotes sparingly, there should only be a few in the paper and they better be good ones. The key difference in citing a direct quote is that you must put quotation marks around the sentence and then cite at the end. IF YOU FAIL TO USE QUOTATION MARKS AROUND A DIRECT QUOTE YOU ARE SAYING YOU WROTE THE SENTENCE. THIS IS PLAGIARISM!!! More information on direct quotes and direct quotes over four lines to follow.

Works Cited Page: This is the last page of your paper where you list, using the format shown below, all the books, articles, web sites, SIRS articles, magazines articles, etc. you have used. This must be done in the proper format. Proper format will be outlined in the following pages.

 I highly recommend the following sites:

Citing A Paraphrase A PARAPHRASE IS:

  • your own rendition of essential information and ideas expressed by someone else, presented in a new form.
  • one legitimate way (when accompanied by accurate documentation) to borrow from a source.
  • a more detailed restatement than a summary, which focuses concisely on a single main idea.

Here is a sample paraphrase:

Original Text: (From Ron Bachman, "Reaching for the Sky." Dial (May 1990): 15.)

While the Sears Tower is arguably the greatest achievement in skyscraper engineering so far, it's unlikely that architects and engineers have abandoned the quest for the world's tallest building. The question is: Just how high can a building go? Structural engineer William LeMessurier has designed a skyscraper nearly one-half mile high, twice as tall as the Sears Tower. And architect Robert Sobel claims that existing technology could produce a 500-story building.

Paraphrase:

How much higher skyscrapers of the future will rise than worlds tallest building, the Sears Tower, is unknown. The design of one twice as tall is already on the boards, and an architect, Robert Sobel, thinks we currently have sufficient know-how to build a skyscraper with over 500 stories (Bachman 15).

Note the following. The writer never uses the exact words of the author therefore there is no need to use quotation marks. The writer summarizes, uses his or her own words and then cites the source at the end. Sometimes a paraphrase will be large and must be broken up. A good rule of thumb is to break up a paragraph that is completely paraphrased into two or three citations. The writer has given credit to the author and thus has avoided plagiarism. Now the author would just continue writing after double spacing.

Your paper will more or less be paraphrase after paraphrase linked together by your own words and analysis. You need to introduce, analyze and put into context the paraphrases you use. This is the nature of the research paper, after all, you are not the expert, they are. If you cite from the same author in the very next citation you do not have to put the authors last name in the in line citation, just the page number.

Example:

How much higher skyscrapers of the future will rise than worlds tallest building, the Sears Tower, is unknown. The design of one twice as tall is already on the boards, and an architect, Robert Sobel, thinks we currently have sufficient know-how to build a skyscraper with over 500 stories (Bachman 15). As a matter of fact the architect William LeMessurier claims he designed a skyscraper that is over a half a mile tall (15).

 

Citing a Direct Quote

Citing a direct quote uses the same form as citing a paraphrase. The differences is that you are using someone else's words directly. In order to avoid plagiarism you MUST USE QUOTATION MARKS unless the direct quote is over four lines.

Here is a sample direct quote:

Original Text: (From "Captain Cousteau," Audubon (May 1990):17.

"The Antarctic is the vast source of cold on our planet, just as the sun is the source of our heat, and it exerts tremendous control on our climate," [Jacques] Cousteau told the camera. "The cold ocean water around Antarctica flows north to mix with warmer water from the tropics, and its upwellings help to cool both the surface water and our atmosphere. Yet the fragility of this regulating system is now threatened by human activity."

Direct Quote:

The importance of the sea to the environment of the earth cannot be underestimated. "The Antarctic is the vast source of cold on our planet, just as the sun is the source of our heat, and it exerts tremendous control on our climate (Cousteau 17)."

Note the following. The first sentence is neither a paraphrase or a quote. It is the writers own words. The writer is introducing and placing the Cousteau quote into context.

Direct Quote Over Four Lines:

Use these VERY RARELY. A great speech or famous quote might justify using a direct quote over four lines. To do this skip a line, indent five spaces on both sides of the quote, single space and use italics. Place the citation on the next line to the lower right of the quote. Go to the next line and then continue with your paper. DO NOT USE QUOTATION MARKS.

Example:

Abraham Lincoln said in his famous Gettysburg Address:

It is rather for us to be here dedicated to the great task remaining before us -- that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion -- that we here highly resolve that these dead shall not have died in vain -- that this nation, under God, shall have a new birth of freedom -- and that government of the people, by the people, for the people, shall not perish from the earth.

(Winthrop 67)

What Lincoln was saying was that those that died had died for a cause. They had died to preserve the Union and to keep the United States together (67 - 68).

Note the following. The long quote follows the format prescribed above. The quote is also followed by a paraphrase from the same author.The citation is the name of the book you found the quote in, not the name of the writer of the quote, if they are different. You must however say who made the quote in prefacing or concluding use of the quote.

When the book has no author use a keyword from the title. Usually the first word in the citation. When there are two book by the same author designate one as book one and the other as book two. For example: (Winthrop1 282) and (Winthrop2 58-71).

Writing The Works Cited Page

Your works cited page is an essential part of the process. The works cited page is the last page of your paper and it tells the reader where he or she may find the sources cited within your paper. It is essential you use the correct form. Remember a few thing when organizing the works cited page:

  • The works cited page must be labeled Works Cited Page. The label should be at the top center of the page.
  • The sources on the page must be listed IN ALPHABETICAL ORDER BY THE AUTHORS LAST NAME.
  • The first line of each entry is flush to the margin, all consequent lines within the entry must be indented five spaces.
  • Entries in the works cited page should be single spaced. Double space in between entries.

Style and Other Hints

  • Make sure your grammar, punctuation and spelling is perfect. Have someone else read and proofread your paper for you. We often do not see our own mistakes.
  • Make sure you answer your thesis, stay organized and make sense!
  • Never use "I" or write in the first person. Always write in the third person.
  • Never begin a sentence with "because," "and," "however," or other linking words.
  • Do not wait for the last minute. Your research will be shoddy and your presentation poor.
  • Use a computer word processor. The enable you to be neat and to make changes. If you don't have one start early so you can use the computers available at school.
  • Keep your paper on disk so that you can make changes and store the disk in a safe place. You may even want to have a copy of the disk for security.
  • Make sure you organize yourself when writing the paper. Keep your notes together with the bibliographic information you will need. You don't want to forget where you found your information.
  • Do not throw anything away until after your paper has been returned, you may need to defend yourself against plagiarism.
  • Do a professional job, my expectations are very high!
  • Putting together a research paper is like a puzzle. You have to fit together all of your research, quotes and paraphrases into a well organized document.

Citing References in Scientific Research Papers

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

Contents

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).

Sources that need to be acknowledged are not limited to books and journal articles, but include internet sites, computer software, written and e-mail correspondence, even verbal conversations with other people (in person or by telephone). All different kinds of sources must be acknowledged. Furthermore, if you use figures, illustrations, or graphical material, either directly or in modified form, that you did not yourself create or design, you need to acknowledge the sources of those figures.

Details of Citing References in your Text

When you cite a reference in your text you should use one of the following three formats:

(1) Mention the author by last name in the sentence and then give the year of the publication in parenthesis:

According to Rodgers (1983), the Appalachian mountains were formed in three events.

(2) Give the facts or ideas mentioned by the author and then attribute these facts or ideas by putting both his or her last name and the date in parenthesis:

The first of the three events occurred in the Ordovician, the second in the Devonian, and the third in the Carboniferous and Permian Periods (Rodgers, 1983).

(3) Quote the author exactly--be sure to put the quoted phrase between quotation marks--and then list the author's name, the date, and the page number in parenthesis:

"All the climaxes produced mountainous islands or highlands that shed vast amounts of debris westward to form clastic wedges or delta complexes on the continental margin." (Rodgers, 1983, p. 229).

You only need to include the page number in the citation if you are quoting directly, or if the source is very long and the specific fact or idea you are citing can only be found on a specific page. Direct quotations that are more than 4 lines long should be set off from the rest of your paper by use of narrower margins and single spaced lines.

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 the reference you are citing has two authors, use the following format:

Periods of glaciation have a large effect on sea level (Ingmanson and Wallace, 1985).

If the reference you are citing has more than two authors, use the following format:

Hot spots are formed by the drift of plates over mantle plumes (Vink et al., 1985).

If your source of information is from a personal verbal communication, you would use the following format for the first citation from that person:

It is possible to correct the raw dD values measured on the mass spectrometer (Mark Conrad, Lawrence-Berkeley National Lab, personal communication).

Later citations to the same person can be shortened, as in:

The reproducibility of dD determined by these methods is thought to be about +/- 2 per mil (Conrad, personal communication).

If your source of information is from written correspondence (a letter or e-mail), you would substitute the word "written" for the word "personal" above, and you would add the date of the letter (if dated). Personal communications are generally not included in the References Cited or Bibliography section, although unpublished papers, reports or manuscripts should be.

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:

The reference citation style described here is a version of the "Author, Date" scientific style, adapted from the Council of Biology Editors (1994).

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.

Details of Formatting Reference Lists

Your list of References Cited should include all of the references you cited in your paper, and no more! It should be arranged in alphabetical order by the last name of the first author. If you have more than one entry by the same author, they should be further ordered by increasing publication date (more recent papers last). If you have multiple sources from a single 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.) You should include enough information that your readers will be able to find these sources on their own. The exact format is not critical, but consistency and completeness is. Reference lists are generally reverse-indented--this just helps the reader to find references to specific authors that much faster. Follow the examples given below and you will be all set.

For Books
List all authors by last name and initials, separated by commas if there are more than two authors. Put an "and" before the last author in the list. Then put the year of publication, the title of the book (in italics if possible), the publisher, the city, and the number of pages in the book.

One author:

Gould, S. J., 1983, Hen's Teeth and Horse's Toes, W. W. Norton, New York City, 413 p.
Two or more authors:
Ingmanson, D. E. and Wallace, W. J., 1985, Oceanography: An Introduction, Wadsworth, Belmont, CA, 530 p.
For Articles or Chapters with separate authors from a Book or Compilation
List the author(s) of the article using the same format given above for books, then give the year, the title of the article or chapter (no quotes, italics or underlines), then the name(s) of the editor(s) of the book or compilation, followed by "ed." or "eds.". Then put the title of the book (in italics if possible), the publisher, the city, and the page numbers where the article can be found:
Rodgers, J., 1983, The life history of a mountain range-- Appalachians, in Hsu, K. J., ed., Mountain Building Processes, Academic Press, Orlando, p. 229-243.
For an Article from a Journal or Magazine
List the author(s) of the article using the same format given above for books, then give the year, the title of the article or chapter (no quotes, italics or underlines), then the title of the journal or magazine (in italics if possible), the volume number of the journal (do not use the publication date), and page numbers where the article can be found:

One author:

Maddox, J., 1987, The great ozone controversy, Nature, v. 329, p. 101.
Two or more authors:
Vink, G. E., Morgan, W. J., and Vogt, P. R., 1985, The Earth's hot spots, Scientific American, v. 252, p. 50- 57.
For Internet sources
Give the author's last name and initials (if known) and the date of publication (or last modification). Next, list the full title of the work (e.g. the specific web page), and then the title of the complete work or site (if applicable) in italics (if possible). Include any version or file numbers, enclosed in parentheses. Most important, provide the full URL to the resource, including the protocol, host address, and the complete path or directories necessary to access the document. Be sure to spell this out exactly! (best to use an electronic "copy" from the "location" box of your browser and "paste" into your word processor). Finally specify the date that you last accessed the site, enclosed in parentheses.
Focazio, M.J., Welch, A.H., Watkins, S.A., Helsel, D.R., and Horn, M.A., 1999, A retrospective analysis on the occurrence of arsenic in ground-water resources of the United States and limitations in drinking-water-supply characterizations, U.S. Geological Survey Water-Resources Investigation Report 99-4279, http://co.water.usgs.gov/trace/pubs/wrir-99-4279/ (August 1, 2000)

Adapt these formats as necessary for other types of sources, including unpublished reports or manuscripts -- just be sure to include sufficient information that your readers could find or obtain these sources themselves, if need be.

Further information can be found by consulting Hansen (1991), Council of Biology Editors (1994), and Harnack & Kleppinger (2000), particularly their chapter on Using CBE Style to Cite and Document Sources.
