Reference List Format Examples

 

Taking Notes for your Research Paper

 

To format your References list:

  • Center the word References in bold at the top.
  • Use 12 point font.
  • Use 1” margins.
  • Double space all entries (without an extra space between entries).
  • Indent the second and all subsequent lines for each entry.
  • Alphabetize entries by last name (or title, if there is no author).
  • All entries, except those with a link or DOI, end with a period.
  • Only include sources you have cited in the paper.
  • When citing an article accessed online, use a stable URL whenever possible.  You may also use a DOI, but for items retrieved from Dalton's catalog or databases the stable URL is preferred.  The format for either a URL or DOI is: http: or https:.
  • Capitalize only the first letter of the first word of a title and subtitle, the first word after a colon or dash in the title, and proper nouns.  Do not capitalize the second word in a hyphenated compound word.

Hughes, J. C., Brestan, E. V., & Valle, L. A. (2004).

(Hughes et al., 2004, p.43)

When a work has 3 or more authors, in-text citations consist of the first author’s name followed by “et al.” (Latin for “and others”), the date, and page number.

The exception to this is when more than one source has the same lead author, in which case list as many authors as needed to differentiate the source.

21 or more

Miller, T.C., Brown, M.J., Wilson, G.L., Evans, B.B., Kelly, R.S., Turner, S.T., Lewis, F., Lee, L.H., Cox, G., Harris, H.L., Martin, P., Gonzalez, W.L., Hughes, W., Carter, D., Campbell, C., Baker, A.B., Fores, T., Gray, W.E., Green, G., ... Nelson, T.P. (2018).

When a work has more than 20 authors, the format for the References list is: include the first 19 authors' names, then insert three ellipsis points, and add the last author's name.

(Miller et al., 2004, p.44)

Special Cases:

  • When citing a source without an individual author, you may use a corporate author.  When there is no author at all, begin your citation with the item's title.
  • For online sources, you may use either a URL or DOI.  In both cases, they must be presented as hyperlinks (http://).
  • When citing an online source that is not static (like a published article) and may change (like a webpage), include an access date and the word Retrieved.  Example: Retrieved April 10, 2018, from http://www.cdc.gov
  • When citing a source without a date, use (n.d.).
  • In-text citations are placed within the sentence, before the punctuation.
  • When citing more than one source in-text, place both sources within the same parentheses and separate them with a semi-colon.

Websites:

Entire website

If you are citing a webpage that may change over time, it is recommended that you include an access date (See examples below for placement.)

If you refer to an entire Web site, you do not need to include an entry for it in your reference list, but must identify the source clearly in the text of your paper. For example:

The Sea Turtle Restoration Project homepage presents a wealth of compelling, well-researched information on the struggle to save the world's sea turtles from extinction (http://www.seaturtles.org).

Specific page within a website

  • When citing an online source that is not static (like a published article) and may change (like a webpage), include an access date and the word Retrieved.  Example: Retrieved April 10, 2018, from http://www.cdc.gov
  • When there is no individual author on a webpage, use the corporate author.  If the corporate author is the same as the name of the website, there is no need to repeat it.
