This page will explain how to cite sources on an APA Style References page. This list will focus on the most common kinds of sources.  Use the examples below to learn how to format the citation for each kind of source.  Remember that reference page citations should be double spaced, with a hanging indent, and each citation in alphabetical order by the author’s last name.

Journal Articles

Journal article citations begin with author last name, followed by first initial, then the year of publication, article title, journal title, volume and issue number, pages and DOI number if there is one.

 

Ingelsrud, L. H., Terluin, B., Gromov, K., Price, A., Beard, D., & Troelsen, A. (2021). Which Oxford knee score represents a satisfactory symptom state.  Acta Orthopaedica, 92(1), 85–90. https://doi.org/10.1080/17453674.2020.1832304

 

Books/eBooks

Books are simple to cite.  Citations begins with author last name and first initial, book title in italics, and lastly the name of the publisher.  This format is the same for books or eBooks.

Dorsey, B & Newman, G. (2018). Lost, Texas : Photographs of forgotten buildings.

Texas A&M University Press.

Website article with an author and a date of publication

It’s always best to find websites with the author name and date of publication if you can.  Here is an example of one.

Neuman, S. (2021, April 27). Oil spill reported off China coast after tanker, bulk carrier collide. NPR.org. https://www.npr.org/2021/04/27/991144729/oil-spill-reported-off-china-coast-after-tanker-bulk- carrier-collide
 

Government & Organization Websites

Government & Organization Websites will not usually list an author for their webpages.  In this case, you will cite the organization itself as the author.  This is known as group authorship.  The idea is the group who created the article is considered the author, not any one person.

Centers for Disease Control and Prevention. (2009). CDC recommendations for the amount of time persons with influenza-like illness should be away from others.  http://www.cdc.gov/h1n1flu/guidance/exclusion.htm
 

Website article with no date

Many websites will not include important information like the date of publication.  The citation for these will say (n.d.) to signify no date.

Smith, A. (n.d.) Human Trafficking. Department of Justice. https://www.justice.gov/humantrafficking

Textbooks

How you cite a textbook will be vary depending on if it has an author or an editor.

Here is how to cite a textbook with an author.  This also shows how to cite a textbook with more than one edition.

Jackson, L. M. (2019). The psychology of prejudice: From attitudes to social action (2nd ed.). American Psychological Association.

Here is an example of citing a textbook that has an editor instead of an author.

Kesharwani, P. (Ed.). (2020). Nanotechnology based approaches for tuberculosis treatment. Academic Press.

 

YouTube

Citing YouTube videos begins with the name of the person or group who uploaded the video, then the date it was uploaded, followed by the title in talics, [Video] in brackets, the label YouTube, and finally the URL.

Harvard University. (2019, August 28). Soft robotic gripper for jellyfish [Video]. YouTube. https://www.youtube.com/watch?v=guRoWTYfxMs
