Avoiding Plagiarism

 

Evaluating Sources

 

 

A citation in the text must clearly direct the reader to an exact source listed at the end of the paper so that the reader can know the exact location from which the information came. Because PaperToolsProª may provide you with more information than you need to make a correct citation, review the following explanation of citation formats, delete any unnecessary information, and make appropriate adjustments.

 

Using the authorÕs name within the text of the paper often creates a smoother sentence and gives more authority to the information than placing it in the parenthetical citation. However, if the authorÕs name appears in the text, make sure you include the remaining necessary information in parentheses following the idea or quotation.

 

 

Modern Language Association (MLA) style

 

For most sources, give the authorÕs last name and the number of the page/s on which the information was found in parentheses with no punctuation. If the entry begins with an editor, translator, or narrator, use that name.

 

(Smith 42)

 

If citing an entire work or citing a one-page work, do not include a page number.

 

(Smith)

 

If the authorÕs name appears in the text, give only the page number/s.

 

Smith disagrees with this viewÉ(42).

 

However, several situations exist which may have modifications to this basic format.

 

If a source has more than one author with the same last name, use the initials of the authorsÕ first names; if these are shared by the two authors, use the full first names:

 

(J. Smith 42) and (S. Smith 298);

(John Smith 42) and (Joseph Smith 298)

 

If two or more authors are listed for a work, include all of their last names; or if there are more than 3authors, give the first authorÕs last name and et al.

 

(Smith, Jones, and Brown 244)

(Smith et al. 339-42)

 

If there is a corporate or government author, use its name shortened or in full. Full name is best used in the text at least the first time.

 

(Apple Computer 74)

(National Institute of Mental Health 44)or (NIMH 44)

 

If there is no author or substitute, use a shortened or full version of the title.

 

(Merriam-WebsterÕs Collegiate Dictionary 637)

                       

If more than one work by the author is listed in the works cited list, add a shortened or a complete title after the authorÕs name and a comma.

 

(Gibaldi, MLA Style Manual 239)

 

If the citation refers to a source that is one volume of a multi-volume source, the volume and page numbers are included.

 

(Smith, vol. 3: 94)

 

If citing an electronic source, use authorÕs last name; if there is no identifiable author, use the Web article title without a page number since page numbers are not stable in this kind of source.

 

(Modern Language Association)

 

For other non print sources (radio or TV programs, films, videos, sound recordings, artworks, maps, charts, interviews or lectures), give only the title or author, which can be a name like the interviewer, interviewee, director, performer, producer.

 

(M.A.S.H) or (Alda)

 

 

American Psychological Association (APA) style

 

For most sources, give the authorÕs last name and year of publication separated by acomma, in parentheses. If the entry begins with an editor, translator, or narrator, use that name.

 

(Smith, 2002)

 

If the authorÕs name appears in the text, give only the year.

 

Smith disagrees with this view (2002).

 

However, several situations exist which may have modifications to this basic format.

 

If more than one author with the same last name is used, distinguish the sources by adding the initial of the authorsÕ first names; if these are shared by the two authors, use the full first names:

 

(J. Smith, 2002) and (S. Smith, 2002) and

(John Smith, 2002) and (Joseph Smith, 2002)

 

If two authors are listed for a work, include both of their last names for every citation.

 

(Smith and Jones, 2002)

 

If there are three, four, or five authors, give the last names of all of the authors for the first citation; if the source is cited again, use only the last name of the first author followed by et al.

 

(Smith, Jones, and Brown, 2002)

(Smith, et al. 2002)

 

If the work has six or more authors, cite the last name of the first author followed by a comma and et al.

 

(Smith, et al.)

 

If two citations with six or more authors are condensed to appear alike, give the surnames of the first author and as many additional subsequent names that are necessary to distinguish the two sources, followed bya comma and et al.

 

(Smith, Jones, Brown, White, Black, and Green, 2002)             

(Smith, Jones, Corning, Petunia, Alberts, and Glass, 2002)

 

This would be shortened to:

 

(Smith, Jones, Brown, et al., 2002) and

(Smith, Jones, Corning, et al., 2002)

 

 If there is a corporate or government author, use the full name each time it appears in a citation. However, associations and government agencies are given as full names in the first citation and can be abbreviated if citing the source again. Make sure that the reader can easily locate that source in the reference list. If the name is readily recognizable, use the full name in the first citation and a shorter version in the following citations

 

First citation: (National Institute of Mental Health [NIMH], 2002)

Following citation: (NIMH, 2002)

 

If there is no author or substitute, use the first few words that begin the entry, which is usually a title.

                                   

(Merriam-WebsterÕs Collegiate Dictionary, 1998)

(ÒPractical Uses,Ó 2002)

                       

If more than one work by the author is listed in the reference list, add a shortened or a complete title after the authorÕs name and a comma.

 

(Smith, The Biology of Frogs, 2002)

 

If citing an electronic source, use authorÕs last name; if there is no identifiable author, use the Web article title without a page number since page numbers are not stable.

 

(Modern Language Association)

 

For other non print sources (radio or TV programs, films, videos, sound recordings, artworks, maps, charts, interviews or lectures), give only the title or author, which can be names like the interviewer, interviewee, director, performer, producer.

 

(M.A.S.H) or (Alda)

 

 

Legal sources:

 

For court cases, cite the name of the case in italics and the year of the decision separated by a comma.

 

(Smith v. Jones, 2002)

 

For statutes, give the popular or official name of the act and the year it was enacted separated by a comma.

 

(Americans With Disabilities Act, 1990)

 

 

American Chemical Society (ACS) style:

                       

The citation in the text is a number in parentheses (1). Number the citations consecutively from (1) to the last citation. In the list of references at the end of the paper, put the same number in parentheses before the source to which the citation refers. When your list of numbered references is complete, arrange them in numerical order. This can readily be done in a word processing program using the ÒSortÓ procedure.

 

 

Council ofBiology Editors (CBE) style:

 

Follow the guidelines used by the ACS except for the format of the numbers; use a number in superscript1. If you refer to two sources in the citation, use the two numbers in superscript1,2. If you refer to more than two sources in the citation, use the first and last number separated by a hyphen in superscript 1-4. In the References page, do not put the corresponding numbers in superscript, but rather use regular sized numbers, followed by a period and one space.

 

 

American Association for the Advancement of Science (AAAS) style:

 

This style, used in the journal Science, uses the numbering method followed by ACS. However, the numbers in the citation are put in italics (1) but not in the References and Notes list at the end.

 

 

The Chicago Manual of Style (CMS):

 

The Chicago Manual of Style (CMS) offers two different styles in which to document researched information.  Use the CMS style for Humanities (CMS-H) when writing about research in the humanities fields, such as literature, history, and the arts; use the CMS author-date style for physical, natural, and social sciences (CMS-S).  Below are sample citation entries for papers that include Bibliography for CMS-H or References and Works Cited for CMS-S.  If these full lists of sources are not included in the final paper, then a completely formatted note or a parenthetical text citation in author-date style is necessary.  Consult The Chicago Manual of Style, 15th edition or your school handbook or website for details to create these full citations from the information that PaperToolsProï uses to create bibliographies.

 

The Chicago Manual of Style (CMS-H):

 

For most sources, give the author last name, the title (a shortened version if it is long) in italics, and the number of the page/s on which the information was found in parentheses with a comma after each item. If the entry begins with an editor, translator, or narrator, use that name.

 

(Smith, Very Bad Prose, 42)

 

If citing an entire work or citing a one-page work, do not include a page number.

 

(Smith, Very Bad Prose)

 

If the author name appears in the text, give only the page number/s.

 

Smith disagrees with this view (42).

 

However, several situations exist which may have modifications to this basic format.

 

If a source has more than one author with the same last name, use the initials of the author first names; if these are shared by the two authors, use the full first names:

 

(J. Smith, Very Bad Prose, 42) and (S. Smith, Very Good Prose, 298);

(John Smith, Very Bad Pros, 42) and (Joseph Smith, Very Good Prose, 298)

 

If two authors of one source share the last name, use only their last names:

               (Smith and Smith, Very Good Prose, 298)

 

If two or more authors are listed for a work, include all of their last names; or if there are more than 3 authors, give the first authorÕs last name and et al.

 

(Smith, Jones, and Brown, 244)

(Smith et al., 339-42)

 

If there is a corporate or government author, use its name shortened or in full. Full name is best used in the text at least the first time.

 

(Apple Computer, 74)

(National Institute of Mental Health, 44) or (NIMH, 44)

 

If there is no author or substitute, use a shortened or full version of the title.

 

(Merriam-WebsterÕs Collegiate Dictionary,637)

                       

If more than one work by the author is listed in the works cited list, add a shortened or a complete title after the authorÕs name and a comma.

 

(Gibaldi, MLA Style Manual, 239)

 

If the citation refers to a source that is one volume of a multi-volume source, the volume and page numbers are included.

 

(Smith, Very Good Prose, 3:94)

 

If citing an electronic source, use authorÕs last name; if there is no identifiable author, use the Web article title without a page number since page numbers are not stable in this kind of source.

 

(Modern Language Association)

 

 

The Chicago Manual Style - Author-Date (CMS-S)

 

For most sources, give the author last name, the year of publication without punctuation between them.  If the entry begins with an editor, translator, or narrator, use that name.

 

(Smith1998)

 

When citing a specific page, its number follows the date and a comma.

 

               (Smith 1998, 73)

 

However, several situations exist which may have modifications to this basic format.

 

If a source has more than one author with the same last name, use the initials of authorsÕ first names; if these are shared by the two authors, use the full first names:

 

(J. Smith 2001, 42) and (S. Smith 2000, 298);

(John Smith 2001, 42) and (Joseph Smith, 2000 298)

 

If two authors of one source share the last name, use only their last names:

               (Smith and Smith 2001, 298)

 

If two or more authors are listed for a work, include all of their last names; or if there are more than 3 authors, give the first authorÕs last name and et al.

 

(Smith, Jones, and Brown 1999, 244)

(Smith et al. 1999, 339-42)
