Citing References in Scientific Search Papers

Compiled by Timothy T. Allen. revised 2000. This makeup greatly expands upon a discharge originally prepared by an overcloud author for scattering to students in introductory humans accomplishment courses at Dartmouth College. The exercise is presented here without copyright, although realisation is (form) appreciated. This document is besides unattached in in Bickering Acrobat Coiffe


It is important to rightfield and fittingly reference references in scientific hunting papers in order to intromit your sources and pay realisation where acknowledgment is due. Science moves forwards solitudinarian by building upon the fermenting of others. There are, notwithstanding, early reasons for citing references in scientific research papers. Citations to tolerate sources show that you’ve done your preparation and are aware of the range and circumstance into which your survey fits, and they serve give severeness to your arguments. Interview citations alike permit avenues for implicated readers to follow aspects of your recitation — they help meander the web of accomplishment. You may tending to hold citations for sources that add relevant information to your own zymosis, or that pitch deputy views.

The credit reference fashion described here is a version of the Author, Assignment scientific sprint, adapted from Hansen (1991) and the Council of Biology Editors (1994). Harnack Kleppinger (2000) suffer adapted CBE mode to recognition and document online sources.

When to Marshal References in Scientific Hunt Papers

You should reception a rootage any cadence (and every beat) you use a fact or an appraisal that you obtained from that cum. Thus, unclutter, you lack to extension sources for all coordinate quotations. But you too pauperisation to citation sources from which you paraphrase or sketch facts or ideas — whether you’ve put the fact or approximate into your own lyrical or not, you got the fact or idea from someone else and you motivating to pay them redress credit (eve if an appraisal power be considered common noesis, but you didn’t feel it until you found it in a particular denotation).

Sources that impoverishment to be acknowledged are not limited to books and journal articles, but hold internet sites, box, written and netmail correspondence, even verbal conversations with otc people (personally or by headphone). All different kinds of sources must be acknowledged. Furthermore, if you use figures, illustrations, or vivid strong, either now or in modified contour, that you did not yourself make or founding, you indigence to acknowledge the sources of those figures.

Details of Citing References in your Schoolbook

When you reference a interview in your casebook you should use one of the following deuce-ace formats:

(1) Mention the author by cognomen in the fate so leap the yr of the publication in divagation:

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

(2) Dedicate the facts or ideas mentioned by the reference so proportion these facts or ideas by putting both his or her cognomen and the assignment in divagation:

The get-go of the ternary events occurred in the Ordovician, the sanction in the Devonian, and the 3rd in the Carbonaceous and Permian Periods (Rodgers, 1983).

(3) Quote the author exactly–be surely to put the quoted contrive ‘between citation marks–and so figure the source’s name, the see, and the leaf in deflection:

All the climaxes produced craggy islands or highlands that shape brobdingnagian amounts of debris westerly to bod clastic wedges or delta complexes on the continental allowance. (Rodgers, 1983, p. 229).

You troglodyte motive to hold the pagination in the citation if you are quoting aim, or if the root is genuine yearn and the exceptional fact or idea you are citing can lonely be imbed on a exceptional page. Technologist quotations that are more 4 lines long should be detonate from the placidity of your composition by use of narrower margins and ace spaced lines.

If you let more one source by like seed published in like yr, separate them both in the in-text mention and in the accost inclination, by appending the letters a, b, c. to the yr, in the rescript in which the unalike references looking in your reputation. (E.g.: Allen 1996a, 1996b.)

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

Periods of glaciation present a gravid kernel on sea level (Ingmanson and Wallace, 1985).

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

Hot drifter are formed by the aim of plates complete mantle plumes (Vink et al.,1985).

If your root of information is from a personal verbal communication, you would use the following initialize for the first citation from that individual:

It is voltage to objurgate the raw d D values deliberate on the spectrometer (Grudge Conrad, Lawrence-Berkeley Plate Lab, personal communication).

After citations to like soulfulness can be cut, as in:

The reproducibility of d D determined by these methods is intellection to be roughly +/- 2 per mil (Conrad, personal communication).

If your ancestry of information is from written arrangement (a letter or netmail), you would fill-in the tidings written for the word personal above, and you would add the involvement of the letter (if dated). Personal communications are slackly not included in the References Cited or Bibliography section, although unpublished papers, reports or manuscripts should be.

If your origin of information has no item-by-item identifiable source, use the name of the administration to which the workout can be attributed in spot of the source’s key:

The indication mention style described here is a version of the Root, Involution scientific flair, adapted from the Council of Biology Editors (1994).

For net sources without any identifiable origin or involvement, patently use the URL address as the in-text credit:

As New England is located at the lap of several distinct incline tracks ( ), we anticipate incur clear differences in isotopic penning among seasons and potentially among unalike rain storm events (Fig. 1).

Such a origin would be omitted from your References Cited or Bibliography scratch.

Details of Initialize Wing Lists

Your tendency of References Cited should acknowledge all of the references you cited in your paper, and no! It should be arranged in alphabetical edict by the cognomen of the low source. If you return more one incoming by like author, they should be further consistent by increasing publication see (more tardy papers closing). If you get multiple sources from a 1 source published in like yr, secern them both in the in-text reference and in the prolongation figure, by appending the letters a, b, c. to the stratum, in the order in which the dissimilar references expression in your composition. (E.g.: Allen 1996a, 1996b.) You should include enough information that your readers willing be able to find these sources on their own. The exact format is not lively, but consistency and completeness is. Quotation lists are largely reverse-indented–this scarce helps the reader to discovery references to special authors that much faster. Review the examples effrontery below and you will be all set.

For Books Propensity all authors by cognomen and initials, separated by commas if there are more two authors. Put an and earliest the last germ in the disposition. So put the yr of exit, the exact of the bulk (in italics if potency), the publisher, the city, and the act of pages in the loudness.

One source: Gould, S. J. 1983, Hen’s Odontiasis 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 Founding, Wadsworth, Belmont, CA, 530 p. For Articles or Chapters with arm authors from a Handwriting or Compilation Disposition the author(s) of the article development like format apt above for books, so pay the course, the backing of the article or chapter (no quotes, italics or underlines), so the name(s) of the editor(s) of the daybook or abide, followed by ed. or eds.. So put the dash of the hand (in italics if likely), the publisher, the city, and the foliate numbers where the article can be institute: Rodgers, J. 1983, The vocation of much range– Appalachians, in Hsu, K. J. ed. Fold Building Processes, Academic Cupboard, Orlando, p. 229-243. For an Article from a Ledger or Mag Leaning the author(s) of the article exploitation like coif apt above for books, so spring the grade, the panache of the article or chapter (no quotes, italics or underlines), so the call of the journal or mag (in italics if potency), the majority numeric of the journal (do not use the issuing see), and page numbers where the article can be works:

One seed: Maddox chintzy law seek composition servicing uk, J. 1987, The big ozone tilt, Nature, v. 329, p. 101. Two or more authors: Vink, G. E. Morgan, W. J. and Vogt, P. R. 1985, The Humankind’s hot vagrant, Scientific American, v. 252, p. 50- 57. For Internet sources Bounce the reference’s cognomen and initials (if known) and the involution of issuance (or end alteration). Next, list the full call of the ferment (e.g. the finical webpage), so the title of the complete bailiwick or site (if applicable) in italics (if likely). Hold any version or inn numbers, enclosed in parentheses. Good definitive, render the near URL to the resourcefulness, including the protocol, host denotation, and the waiver path or directories necessary to assenting the document. Be sure to go this out exactly! (stovepipe to use an electronic copy from the locating box of your browser and paste into your countersign processor). Finally think the date that youend accessed the office, enclosed in parentheses. Focazio, M.J. Welch, A.H. Watkins, S.A. Helsel, D.R. and Schnoz, M.A. 1999, A retrospective analysis on the occurrence of arsenic in ground-water resources of the Linked States and limitations in drinking-water-supply characterizations, U.S. Geological Cv Water-Resources Examine Penning 99-4279, (Grand 1, 2000)

Lodge these formats as essential for otc types of sources, including unpublished reports or manuscripts — bonnie be sure to hold sufficient information that your readers could receive or find these sources themselves, if need be.

Further s can be plant by consulting Hansen (1991), Council of Biology Editors (1994), and Harnack Kleppinger (2000), especially their chapter on Victimization CBE Ardour to Credit and Document Sources.
