When creating a presentation, you need to cite the books, articles, and images you use.
For books and articles you've used, cite them in a reference list at the end of your presentation like this:

You should cite any sources you use in a reference list at the end of the presentation just like you would at the end of a research paper.
You should also cite any images you used in your presentation. Here is an example of how to cite an image:
