Give the author's name and the year of publication. If the author's name is stated in the sentence, always place the year in parentheses immediately after the name.
(Clark, 2019).
Clark's (2019) study shows that . . .
Give both names separated by the word and when including the names in the text of a sentence. For citations in parentheses use an ampersand (&).

OR
(ALL citations) (Sawyer et al., 2010).
If the first author's name and the years of publications are the same for several references, include enough additional co-author names to eliminate ambiguity. Include a comma after the last name.
(Martinez, Fuentes, et al., 2016).
(Martinez, Aguilar, et al., 2016).
Multiple works by the same author
For works published in the same year by the same author, add alphabetic designators to the year in both the in-text reference and reference list.
(Anderson, 2003a, 2003b).
For works published in different years by the same author, place years in chronological sequence separated by commas.
(McBride, 2003, 2007).
Multiple works by the same author and the same year
When multiple references have an identical author (or authors or the in-text citation shortens to the same author) and the same publication year or no publication year, include a lowercase letter after the year in the reference list and in each in-text citation. When you have no date add a hyphen before the lowercase letters. Assign the letters according to the order of the references in your reference list. List references alphabetically by the first word after the date element when the authors and the dates match.

When authors of 2 works published in the same year have the same surname, include the initials of the author in the in-text citation and separate the names by a semicolon and space. When using initials in the text of a sentence do not invert the first name.

If an organizational author is referenced only once or twice in a document, the full organizational name is acceptable. A shortened form can be used in the in-text reference if the organization has a familiar abbreviation. If using an abbreviated name for an organization, spell out the full name the first time referenced and give the abbreviation.
FIRST citation National Library of Medicine (NLM, 2015)...

OR
FIRST citation (National Library of Medicine [NLM], 2015).
(NLM, 2015).
Begin the in-text reference with the first word or first few words of the title, followed by a comma (a lengthy title may be shortened). Titles of an article, chapter or web page should be placed in double quotation marks. Titles of a periodical, book, report, or brochure should be italicized.
ARTICLE title ("A New Deal," 2003).
BOOK title (The Open Box, 1823).
LONG book title (Handbook of Geriatric, 2000).
Reference: Handbook of geriatric drug therapy. (2000). Springhouse.
Works with Anonymous listed as author
When a title lists the author of a work as Anonymous give the word Anonymous as the author's name in-text and in the reference list. Do not use the term Anonymous for works without authors listed.
Anonymous (1983) said...
(Anonymous, 1983).
Place the abbreviation n.d. (for no date) in place of the year for in-text citations and the reference list.
Brigmeyer (n.d.) associates...

Works without Pagination (when using a direct quote)
Use the abbreviation para. to indicate a numbered paragraph rather than a page number.
Horowitz (2011) says, "those who..." (para. 3).
He says, "those who..." (Horowitz, 2011, para. 3).
OR
When no page numbers or paragraph numbers are present, use a heading title and the number of the paragraph after the heading. Click here to see the sample reference below.
Kona (2010) says of George Carlin's humor that, "comedy is a disguise for unmasking other faces" ("The Carlinesque in George Carlin," para 2).
The author likens George Carlin's humor to "a disguise for unmasking other faces" (Kona, 2010, "The Carlinesque of George Carlin," para. 2).
Personal communications (interviews, e-mail correspondence, lectures, etc.) should be used sparingly. When citing personal communications only cite this material in text, do not include personal communication citations in the reference list. They are excluded from the reference list because this is unrecoverable data. Give the name of the speaker and the exact date.
A. M. Raulson (personal communication, January 28, 2020) says...
(T. J. Mavin, personal communication, April 15, 2019).
Sometimes you need to reference an idea using secondhand knowledge. This should be done rarely, it is always better to read the original work to get the most objective meaning. You ALWAYS cite the material you have in front of you, never use another author's references to cite material you have not accessed. When a work is out of print or hard to find, you may wish to use that author's idea in your paper. You need to give credit to the original author/thinker, but you cite the material you found it in, this way the reader can find the material as well. If you reference an out of print/hard to find item, your reader will not be able to find the same material.
Rawlings said (as cited in Belleville, 2006, p. 8), "we need above all...a certain remoteness from urban confusion."
In the reference list cite the work YOU read:
Belleville, B. (2006). Losing it all to sprawl: How progress ate my cracker landscape. University Press of Florida.
Direct Quotations
Direct quotes should be used sparingly in any research paper. Use direct quotes to emphasize a particularly original turn of phrase or when technical lingo does not allow for proper rephrasing. When directly quoting, enclose the entire quote in quotation marks, copy the original wording exactly, and provide a page/line/paragraph number (when available).
Moffett (2010) goes into great detail about the predatory and army-like nature of a colony of ants ensnaring its meal, "the more the worm or grasshopper struggles, the more the masses converge on it...all the little ant jaws hold their prey taut" (p.39).
Block quotations are direct quotations that contain 40 words or more. When quoting more than 40 words, do not use quotation marks; instead, set off the direct quote starting it on a new line and indenting a half inch from the margin.
The authors categorize chronic neck pain,
when symptoms are present for 3 or more months, with either recurrent (multiple episodes separated by
periods of recovery) or persistent (no periods of recovery) pain. Strong evidence suggests that biomechanical factors,
including repetitive movements, prolonged computer use, and poor workstation design, are associated with
the development of neck pain. (Bruflat et al., 2012, p. 1349)
Multiple Citations by the Same Author in One Paragraph
Sometimes you might use the same source of information for an entire paragraph. In this case, you do not need to reference the author and year at the end of each sentence. You would want to provide the full in-text citation at the beginning and the end of the paragraph, but the sentences in between can reference just the author or organization. If you place the author's name in parentheses, then provide the year too.
According to Spitzer's (2010) study the effects of radiation on humans presents...Spitzer's study developed the guidelines needed to test...The most important find in Spitzer's study was that....Spitzer concluded the benefit of radiation...The evidence that proves these guidelines work...(Spitzer, 2010).
