DOCUMENTING SOURCES

Whenever you use another’s words, facts, or ideas – whether as a direct quote or paraphrased into your own words - you must cite the source. This allows you to avoid plagiarism, while enabling the reader of your work to verify or follow up on your research. The most practical way to supply this information is to insert a brief parenthetical acknowledgement within the body of your text. Each of these in-text references must point clearly to a specific citation that appears in a Works Cited list at the end of your paper. It is easiest to draft your Works Cited list in advance, so you will know what information to put in your parenthetical citations.  

CREATING PARENTHETICAL CITATIONS

Here are the rules you must follow:

1. The in-text reference must match the beginning of the full Works Cited citation exactly, so your reader will know which source in the Works Cited list you used for that section of text. 

2. A parenthetical reference consists of the author’s last name (or the beginning of a title that has no author) and a page number (for print sources), with no punctuation between them. (Provide enough information to get the reader to proper place in the Works Cited.) If the source is a website, no page numbers should be included. Page numbers from a printout of a website will vary from printer to printer, and are not reflective of the actual source.

e.g.: (Doctorow 23).

3. A parenthetical citation always goes OUTSIDE OF A QUOTATION and usually BEFORE A PUNCTUATION MARK, such as a period (see example above). However, it goes after the period at the end of a block quote (See 13., below).

                        e.g.: (direct quote): ...despite all we know" (Jones 81).
                       
e.g.: (block quote): ...despite all we know. (Jones 81)

4. Use one citation at the end of a long section of material that comes from one source and the same page. Do not cite at the end of each sentence. For a consecutive reference to the same source, but a different page, use the new page number only in the citation.

5. For the sake of variety, and to avoid long citations, place reference information, such as the author’s name, in a previewing sentence or signal phrase. The following parenthetical citation includes a page number only.

e.g.: In his recent study, Peter Brown states that … (23).

6. For electronic sources, include author’s last name only, or the beginning of the page title if there is no author. Do not use page numbers from a printout.

7. For title entries, be sure to italicize or use quotation marks, just as in the Works Cited. Shorten the title if it is long, but be sure to use the beginning words by which the title is alphabetized.

                        e.g.: (Mr. Lincoln 23).

8. When there is more than one work by the same author, include author’s last name, comma, abbreviated title and page number (for print sources) with no punctuation between.                                                    

e.g.: (Brown, Mr. Lincoln 23).

9. When the Works Cited list includes two authors with same last name, include the author’s first and last name within the body of your text, or add the author's first initial to the parenthetical citation.

e.g.: (P. Brown 23).

10. If a single source has two authors, include last names of both authors within the body of your text or in the parenthetical citation. For three or more authors, include the first author’s last name followed by “et al.”

e.g.: (Brown and Smith 23).

e.g.: (Brown, et al. 23).

11. When citing a source quoted within another source, include the author of the words as “qtd. in” the author of source.

e.g.: (Brown qtd. in Smith 23).

12. When citing two sources in a single parenthetical reference, cite them as you normally would and place a semicolon between them.

    e.g.: (Brown 23; Smith 47)

13. When a direct quote (or a poem) takes more than four lines of text in a research paper, format it as a block quote. To do this:

  • Introduce the quote with a lead-in phrase followed by a colon (e.g., Smith stated in his lecture:)

  • Start the quote on a new line

  • Indent one inch from the left margin throughout the quote

  • Double-space the quote

  • Omit any quotation marks, since by definition, text formatted this way is assumed to be a direct quote

  • Place a parenthetical reference after the concluding period of the quote (See 3., above).
