Start the Reference list on a new page and include the word "References" in uppercase and lowercase centered.
The References list should be double-spaced. Each entry should be formatted with a hanging indent.
References cited in text must appear in the References list and vice versa. The only exceptions to this rule are personal communications and classical works; they are cited in text only and are not included in the References list.
Use ONLY the initial(s) of the author’s given name, NOT the full name.
If the References list includes 2 or more entries by the same author(s), list them in chronological order with the earliest first.
If the author’s name is unavailable, use the first few words of the title of the article, book or Web source, including the appropriate capitalization and italics formatting. E.g. (Scientists Say, 2000).
Arrange References entries in one alphabetical sequence by the surname of the first author or by title or first word if there is no author. Ignore the words A, An, and The when alphabetizing by title.
In titles and subtitles of articles, chapters, and books, capitalize only the first letter of the first word and any proper nouns, except in parenthetical (in text) citations.
Italicize book titles, journal titles, and volume numbers. Do NOT italicize issue numbers.
Do NOT include retrieval dates unless the source of the material may change over time such as a blog entry or wikis.
If a Digital Object Identifier (DOI) is listed on either a print or an electronic source it is included in the reference. A DOI is a unique alphanumeric string that is used to identify a certain source (typically journal articles). It is often found on the first page of an article. Example: http://doi.org/10.1080/146222004
When the References entry includes a URL that must be divided between two lines, break it BEFORE a slash or dash or at another logical division point. Do NOT insert a hyphen if you need to break a URL or a period at the end of the URL.
How to Cite a Direct Quote
When you incorporate a direct quotation into a sentence, you must cite the source. Fit quotations within your sentences, enclosed in quotation marks, making sure the sentences are grammatically correct.
Gibaldi (2003, p. 109) indicates that, “Quotations are effective in research papers when used selectively.”
Remember that “[q]uotations are effective in research papers when used selectively” (Gibaldi, 2003, p. 109).
In 2003, Gibaldi wrote that, “Quotations are effective in research papers when used selectively” (p. 109).
If a quotation is 40 words or more, omit quotation marks and use a block format in which the quotation is indented about ½ inch (or 5 spaces) from the left margin.
How to Cite Summaries or Paraphrases
Even if you put information in your own words by summarizing or paraphrasing, you must cite the original author or researcher and the date of publication. You are also encouraged to provide a page or paragraph number; check with your instructor to see if page numbers are required.
For example, a paraphrase of Gibaldi’s earlier quotation might be identified as follows:
Within the research paper, quotations will have more impact when used judiciously (Gibaldi, 2003, p. 109).

How to Cite Sources when the Primary Authors have the same Surname
If two or more of your sources are written by authors with the same surname, include the first author's initials with the surname in every in-text reference.
Example: Among studies, we review M. A. Light and Light (2008) and I. Light (2006) ...
How to Cite Works with the Same Author and Same Date
When citing multiple works by the same author with the same date, link your in-text citations to your references by adding a letter to the end of the year in both: (Smith, 2015a), (Smith, 2015b), (Smith, 2015c), etc.
How to Cite Different Numbers of Authors
When a work has 2 authors, cite both names every time the reference occurs. When a work has 3 or more authors you only include the first author's name followed by "et al.".
How to Cite Information If No Page Numbers Are Available
If a resource contains no page numbers, as can be the case with electronic sources, then you cannot include a page number in the parentheses. However, if the source indicates paragraph numbers, use the abbreviation “para” and the relevant number in the parentheses. If the paragraph number is not visible, cite the heading and the paragraph number following it.
As Myers (2000, para. 5) aptly phrased it…
(Beutler, 2000, Conclusion, para. 1)
How to Cite Information When You Have Not Seen the Original Source
Sometimes an author writes about research that someone else has done, but you are unable to track down the original research report. In this case, because you did not read the original report, you will include only the source you did consult in your References. The words “as cited in” in the parenthetical reference indicate you have not read the original research.
Fong’s 1987 study (as cited in Bertram, 1996) found that older students’ memory can be as good as that of young people, but this depends on how memory is tested. [Do not include Fong (1987) in your References; do include Bertram (1996).]
How to Cite when you are Altering a Direct Quote
When you need to leave out part of a quotation to make it fit grammatically or because it contains irrelevant/unnecessary information, insert ellipses.
If you must add or slightly change words within a quotation for reasons of grammar or clarity, indicate the change with square brackets.
All sources of information and data, whether quoted directly or paraphrased, are cited with parenthetical references in the text of your paper .
Example: (Walker, 2003).
Double-space your entire paper, including the References list and any block quotes .
