Your professor's directions for APA style are more important that the settings on this template.  You need to make any necessary changes to match your professor's assignment. 

Annotated Bibliography

An Annotated Bibliography is a special way of listing your sources and often has two parts:

1) the complete citation for that source

2) a summary, evaluation, or review of that source in paragraph form.

The purpose of an Annotated Bibliography can vary.  It can provide a summary of the source for other readers.  It can evaluate the source in terms of credibility and usability for a research project.  It can review the source for purpose and clarity.  There are other purposes for an Annotated Bibliography, but these are the most common.  Follow your professor's instructions on how to write your Annotated Bibliography.

Example Below:

Personal Interviews

There is no need to include personal interviews in your References page because the information is not retrievable. If you cite a personal interview in a paper, simply use an in-text citation. This citation will look like this:

(J. Doe, personal communication, December 16, 2019).

-or-

(Personal communication, December 16, 2019).

Published Interviews (Online, Books, etc.)

Published interviews can be found in a variety of places. To cite the interview, follow the format for the appropriate reference type: book, movie, podcast, etc.

Oral History/Narrative

Last name, First initial. Nation/Community. Treaty Territory (if applicable). Where they live (if applicable). Topic/subject of communication (if applicable). personal communication. Month Date, Year.

Example: Cardinal, D. Goodfish Lake Cree Nation. Treaty 6. Lives in Edmonton. Oral teaching. personal communication. April 4, 2004.

According to the American Psychological Association (APA), any AI response is not retrievable by another person.  Normally, this would result in the creation of a personal communication citation.  However, since AI is not technically a person, APA has chosen to cite all AI responses as software (McAdoo, 2023). 

Artificial Intelligence (AI)

Author. (Year of the version of the software). Title of software. [Descriptor of software]. URL of software

Example: OpenAI. (2023). ChatGPT (Mar 14 version) [Large language model]. https://chat.openai.com/chat

"Let's break that reference down and look at the four elements (author, date, title, and source):

Author: The author of the model is OpenAI.

Date: The date is the year of the version you used. Include only the year, not the exact date. The version number provides the specific date information a reader might need.

Title: The name of the model is “ChatGPT,” so that serves as the title and is italicized in your reference, as shown in the template. Although OpenAI labels unique iterations (i.e., ChatGPT-3, ChatGPT-4), they are using “ChatGPT” as the general name of the model, with updates identified with version numbers.

The version number is included after the title in parentheses. The format for the version number in ChatGPT references includes the date because that is how OpenAI is labeling the versions. Different large language models or software might use different version numbering; use the version number in the format the author or publisher provides, which may be a numbering system (e.g., Version 2.0) or other methods.

Bracketed text is used in references for additional descriptions when they are needed to help a reader understand what’s being cited. References for a number of common sources, such as journal articles and books, do not include bracketed descriptions, but things outside of the typical peer-reviewed system often do. In the case of a reference for ChatGPT, provide the descriptor “Large language model” in square brackets. OpenAI describes ChatGPT-4 as a “large multimodal model,” so that description may be provided instead if you are using ChatGPT-4. Later versions and software or models from other companies may need different descriptions, based on how the publishers describe the model. The goal of the bracketed text is to briefly describe the kind of model to your reader.

Source: When the publisher name and the author name are the same, do not repeat the publisher name in the source element of the reference, and move directly to the URL. This is the case for ChatGPT. The URL for ChatGPT is https://chat.openai.com/chat. For other models or products for which you may create a reference, use the URL that links as directly as possible to the source (i.e., the page where you can access the model, not the publisher’s homepage)" (McAdoo, 2023, para. 10-15).

Basic Format for In-Text Citations

The punctuation at the end of the sentence goes after and outside the parenthesis. Words go here (Smith, 2019, p. 263). 

If you are using a direct quote, there is no comma between the end of the quotation and the in-text citation.  "this is a quote" (Smith, 2019, p. 263). 

If you are directly quoting more than one page that ARE consecutive, use a dash between the numbers (Smith, 2019, pp. 263-265). 

If you are directly quoting more than one page that are NOT consecutive, use a comma between the numbers (Smith, 2019, pp. 263, 265). 

If you are citing multiple sources in one in-text citation, use a semi-colon between the citations (Smith, 2019, p. 263; Jones, 2018, p. 138). 

Basic Format using Paraphrasing

If paraphrasing, in parenthesis, list the author's last name followed by a comma and the year of publication. The punctuation at the end of the sentence goes after and outside the parenthesis. 

(Author's last name, year). 

Example: Citing sources is very important (Smith, 2019).

Basic Format using a Direct Quote

If directly quoting, in parenthesis, list the author's last name followed by a comma and the year of publication followed by a comma and the page number(s). 

(Author's last name, year, p.#).

If multiple pages, use "pp." (Author's last name, year, pp.#). 

Example: It should be noted that "proper usage of citations is crucial" (Smith, 2019, p. 263).

Author in Text using Paraphrasing

If paraphrasing the author in text, list the author in the sentence without parenthesis, include the year of publication in parenthesis immediately afterwards and then the paraphrased information.

List the Author's last name (year) and the paraphrased information. 

Example: Smith (2019) states citing sources is very important.

Author in Text using a Direct Quote

If directly quoting the author in text, list the author in the sentence without parenthesis, include the year of publication in parenthesis immediately afterwards and then the quoted information. List  page number(s) at the end of the sentence in parenthesis.

List author's last name (year), "direct quotation inside quotation marks" (p. #).

Example: In his article on citations, Smith (2019) states that "proper usage of citations is crucial" (p. 263).

No Author

If there is no author, list a shortened version of the title in place of the author followed by a comma and the year of publication.

("Shortened title," year). 

If directly quoting, after the year of publication and a comma, list the page number.

If the article is entitled "Very long work can be exhausting to read," the title can be shortened to "Very long work." 

Example: This article is very long ("Very long work," 2019).

Two Authors

If paraphrasing two authors, list the last names of both authors connected with "&" followed by a comma and the year of publication.

(Author's last name & Second author's last name, year).  

Example: Citations are academically honest (Smith & Jones, 2019).

If directly quoting two authors, list the names of both authors connected with "&" followed by a comma and the year of publication and a comma and the page number. 

(Author's last name & Second author's last name, year, p. #). 

Example: "Using citations creates a positive environment for authors" (Smith & Jones, 2019, p. 277). 

Three or more Authors

If paraphrasing three or more authors, list the first author followed by “et al.” followed by a comma and the year of publication. 

(Author's last name et al., year). 

[et al. is Latin for "and others" and has a period after the al. followed by a comma and then the year].

Example: Citations have saved millions of papers (Smith et al., 2019).

If directly quoting, list the first author followed by “et al." followed by a comma and the year of publication followed by a comma and then the page number. 

(Author's last name et al., year, p. #). 

Example: "Citations have helped students all over the world avoid plagiarism," (Smith et al., 2010, p. 42). 

Group or Corporate Authors

If using a group or corporate author, list the name or abbreviation of the group/company/agency in place of the author; followed by a comma and the year of publication.

If a direct quote, after the year of publication and a comma, list the page number.

If paraphrasing: (Group name, year). 

If directly quoting: (Group name, year, p. #). 

Example: It has been reported that “failure to use citations is a threat to national security” (National Security Agency, 2019, p. 27).

No Date

If there is no date, put (n.d.) for year.  Place a period after n and d with no spaces in between.

If directly quoting, include a comma after d. before the year (author, n.d., year).

The "n.d." stands for "No Date."  Be sure to use n.d. on the References page to match the in-text citation. 

Example: The citation was long but did not have a date (Smith, n.d.). 

Two or More Authors with the Same Last Name

If there are two or more authors with the same last name,  list the first name initial(s) and then the last name followed by a comma and then the year.

(A. Author's last name, year).  (B. Author's last name, year) where A and B are the authors' first name initials for each author, respectively. 

If directly quoting, after the year of publication and a comma, list the page number.

Example: 

The glass is half full (A. Smith, 2019). 

The glass is half empty (B. Smith, 2019).

Citing Works with the Same Author and Date

If multiple references have an identical author (or authors) and year of publication, list a lowercase letter after the year.

The References page for these citations needs to have the year of publication exactly match the in-text date with the added lowercase letter. 

(Author last name, yeara)

(Author last name, yearb)

If directly quoting, after the year of publication and a comma, list the page number.

Example: 

(Redd, 2017a).

(Redd, 2017b).

No Pages

If directly quoting and a website or other source has no page numbers; list the paragraph number, section title, table number, slide number, etc.

Paragraph is shortened to "para."  Most other sources use the full word, such as Table, Graph, Chart.

Example: There is some evidence to suggest that "citations have the potential to help grades" (Smith, 2019, para. 5).
