How to Cite Sources in a PowerPoint Presentation

To cite sources in a PowerPoint presentation, do two things: put a short credit on the slide where the borrowed material appears, and list the full entries on a references slide at the end of the deck. The same two layers answer “how to cite in a powerpoint presentation” and “how to cite references in a powerpoint”. This guide shows what each layer looks like, with worked examples in APA 7th edition, and covers the extra case where the thing you are citing is itself a slide deck.

The format: two layers, plus the slide-deck entry

How to cite sources in a PowerPoint presentation

Use in-text citations throughout the presentation where they apply, and list your references on a slide at the end (The Learning Portal, College Libraries Ontario). Check first which citation style your assignment requires, and follow your instructor’s preference if it differs (same guide). Library guidance on slideshow-specific formatting is consistent on one point: APA has no specific rule for formatting a PowerPoint or slideshow (Golden West College Library, APA 7 guide; George Washington University Himmelfarb Library, which advises checking your instructor’s preferences). So the two-layer approach below is the accepted practice rather than a fixed rule.

Layer 1, on the slide: an in-text citation for any quote, paraphrase, image, graph, table, data, audio or video file (Golden West College Library). Format: (Author, year).
Layer 2, at the end: a “References” slide, or several, using the same format as an APA references page (Golden West College Library).
Title slide: include the same information you would put on a title page (Golden West College Library).

When the source you cite is itself a slide deck

Two library guides agree on the reference-list pattern for a deck you found or were given (Frederick Community College Library and George Washington University Himmelfarb Library, both accessed 2026-10-29):

Author, A. A. (Year). Title of presentation [PowerPoint slides]. Site or course system name. URL

Author, year and title come first; Frederick’s guide italicizes the title and adds the site or course system name before the URL.
The format goes in square brackets right after the title. Frederick’s and GWU’s examples write [PowerPoint slides]; Brenau University Libraries writes [PowerPoint presentation]. Pick one and use it throughout.
For slides behind a course login, GWU’s guide says not to include the long link from the course system and to give the system’s home page instead; Frederick’s guide does the same with a login URL.
If the slides are not available online, Frederick’s guide says to cite them in the text only, as a personal communication, and leave them out of the reference list. GWU’s guide likewise treats your own notes from a lecture as personal communication.

Examples

All sources below are invented for illustration. They are labelled examples, not real people or real decks.

A deck posted on a public site

Example reference: Sloan, C. (2020, May 20). Crafting an argument [PowerPoint slides]. SlideShare. https://www.slideshare.net/fictionalurl

A deck on a course system

Example reference: Sloan, C. (2020, May 20). Crafting an argument [PowerPoint slides]. Blackboard. https://frederick.blackboard.com/

A deck with no date

Brenau’s guide says to use “n.d.” where you would normally put the date when none is given. Example in-text form: (Rivera, n.d.).

Slides that readers cannot retrieve

Cite in the text only, as a personal communication, and omit them from the references slide. Example, following the Frederick guide’s pattern: (C. Sloan, personal communication, May 25, 2020).

In-text citation version: credits on the slides

On the slide itself, keep the credit short and matching the entry on your references slide.

Paraphrase: (Sloan, 2020).
Direct quotation from a slide deck: add the slide number, for example (Sloan, 2020, Slide 4). Frederick’s guide gives this form, and Brenau’s guide notes that APA does not provide specific rules for directly quoting PowerPoint slides, so it recommends giving the slide number.
Images and photographs: Golden West College’s guide treats a photograph as a figure in APA style and advises getting approval from the creator or owner before using an image. It lists images among the items that need an in-text citation, so credit them in the same (Author, year) form.
Clip art from Office: the same guide says no citation, permission or copyright attribution is necessary for clip art from programs like Microsoft Word or PowerPoint.

A works cited slide is the same idea under a different name: APA calls the closing list “References”, and the Golden West guide uses that label for the slide. If your instructor or journal requires a different style, use the list title and entry patterns that style prescribes.

Common errors

Credits on slides but no references slide. The in-text credit points to an entry that does not exist. The Learning Portal guide asks for both.
Copying the long course-system link. GWU’s guide says not to include the long Blackboard URL; give the system’s home page instead.
Treating unpublished lecture slides as a reference entry. If readers cannot retrieve the slides, they go in the text as a personal communication.
Switching bracket labels or credit styles mid-deck. Choose [PowerPoint slides] or [PowerPoint presentation] and one credit format, and keep them throughout.
Leaving out image credits. Golden West exempts only clip art from programs like Word or PowerPoint; for other images it asks for an in-text citation and permission from the creator or owner.

For manuscripts, theses and defenses

Defense slides, conference talks and poster-style talks follow the same two layers, with the reference entries written in the style of your thesis or manuscript so the deck and the document agree. Our guide to the thesis defense presentation covers structure and timing, and how to cite a talk in APA and how to cite a poster cover those formats. If you manage references with software, citing sources in PowerPoint with Zotero shows the tool routes for building the references slide.

Style-guide edition

The examples follow APA 7th edition (2020), the current edition of the APA Publication Manual as of 2026-10. The slide-deck pattern above comes from library guides to APA 7, because APA does not publish formatting rules for slideshows themselves. For MLA (9th edition, 2021) or Chicago (18th edition, 2024), use that style’s own patterns for each entry on the references slide.

FAQ

How do I cite sources in a PowerPoint presentation?

Add a short in-text citation, such as (Author, year), on every slide that uses borrowed material, then end the deck with a references slide that lists the full entries.

How do I cite in a PowerPoint presentation when I quote?

Put the quotation in quotation marks and add the author, year and the slide or page it came from. For a quote from a slide deck, Frederick’s guide adds the slide number, for example (Sloan, 2020, Slide 4), and Brenau’s guide recommends giving it.

How do I cite references in a PowerPoint?

Create a final slide titled “References” and format each entry as you would on an APA references page (Golden West College Library). If you cite a slide deck, use the pattern Author. (Year). Title [PowerPoint slides]. Site. URL.

What is a works cited slide?

It is the closing slide that lists every source used in the deck. In APA the list is called References; use whatever title your required style prescribes.

Do I need to cite clip art?

Not for clip art from programs like Microsoft Word or PowerPoint, according to Golden West College’s guide. For images from other places, the guide asks for an in-text citation and approval from the creator or owner.
