Citing Images in PowerPoint Slides (in ASA/SSSA)

ASA and SSSA do not have a uniform way to cite images within PowerPoint slides (neither does APA or MLA for that matter). Therefore, your goal should be keeping your presentations clean, clear, and consistent. If you are doing a presentation for a class it may be a good idea to ask your instructor how they prefer for you to cite images.

Typically you have a two options. I prefer option #1

1. Insert a References slide at the end of the presentation with a list of sources (and use a parenthetical reference on the individual slides). Some presentations also delineate both a References and an Images Used slide at the end of the presentation.

 

2. Create the citation directly on the slide where the image is by adding a text box which contains the properly formatted citation (typically using a smaller font).

In-Text Citations

In Text Citations 

In-text citations are citations that occur within the body of your paper.  SSSA utilize the author-year notation system. Below are some examples.

 

Single author:

There has been at least 532 volcanic eruptions in recorded history (Ramos, 2015).

Ramos (2015) found 532 volcanic eruptions in recorded history.

 

Two authors:

There has been at least 532 volcanic eruptions in recorded history (Ramos and Wilson, 2015).

Ramos and Wilson (2015) found 532 volcanic eruptions in recorded history.

 

More than two authors 

There has been at least 532 volcanic eruptions in recorded history (Ramos et al., 2015).

Ramos et al. (2015) found 532 volcanic eruptions in recorded history.

 

More than two studies cited

There has been at least 532 volcanic eruptions in recorded history (Ramos and Wilson, 2015; Martinez, 2019).

Ramos and Wilson (2015) and Martinez (2019) both found 532 volcanic eruptions in recorded history.

 

If citing a specific page instead instead of an entire chapter or article

There has been at least 532 volcanic eruptions in recorded history (Ramos, 2015, p. 42).

Ramos (2015, p. 42) found 532 volcanic eruptions in recorded history.

 

Reference List

The reference list (or reference section) of your paper contains a list of all of the resources that you cited. Here's some things to keep in mind when creating an SSSA reference list:

  • Arrange the list alphabetically by the last name of authors.
    • In the reference list itself, give the names of all authors. Optionally, if the paper has more than six authors, the rest may be abbreviated to 'et al.'
  • Two or more articles by the same author (or authors) are listed chronologically.
