How to Cite Lecture Slides in APA 7th Edition
Citing lecture slides in APA 7th edition comes down to one question before you write a single letter: can your reader retrieve these slides? The answer determines whether you write a full reference list entry or a short personal-communication note in your text. Get that decision right and the rest of the format follows directly from the official APA Style guidance on PowerPoint references (Publication Manual, 7th ed., Section 10.14).
What Is the APA Format for Lecture Slides?
The APA 7th edition format for lecture slides treats the instructor as the author, the platform (usually a learning management system) as the source, and uses a format descriptor in brackets to tell readers what type of file they would find. The structure mirrors standard APA reference logic: Author, A. A. (Year, Month Day). Title in sentence case [PowerPoint slides]. Source. URL.
The Reference List Entry
Each element of the reference list entry carries a specific job. The author element names the instructor who created or uploaded the slides. The date element includes the year first, then the month and day in a comma-separated parenthetical. The title goes in italics and uses sentence-case capitalization. The bracket descriptor immediately follows the title before the closing period. The source names the platform, and the URL points to the login or home page rather than a direct deep link that would break or require credentials.
| Element | What to write | Example |
|---|---|---|
| Author | Last name, initials. Separate multiple authors with commas and an ampersand. | Smith, J. A. |
| Date | (Year, Month Day). | (2024, September 10). |
| Title | Italic, sentence case. | Introduction to molecular biology |
| Format descriptor | [PowerPoint slides] or [Lecture notes] in brackets, before the period. | [PowerPoint slides]. |
| Source | LMS or platform name. | Canvas. |
| URL | Login or home page URL, no period at end. | https://canvas.university.edu |
The six elements of an APA 7th edition lecture slide reference, in order.
The In-Text Citation
The in-text citation for lecture slides follows the same author-date pattern as every other APA source. Use the instructor's last name and the year the slides were published or posted. For a parenthetical citation, place both inside parentheses at the end of the sentence: (Smith, 2024). For a narrative citation, integrate the name into the sentence and place only the year in parentheses: Smith (2024) noted that...
When you quote directly from a slide, add the slide number after the year: (Smith, 2024, Slide 7). APA does not use page numbers for slides, so "Slide" replaces the page marker. If the slides carry no numbering, use a section title or describe the location: (Smith, 2024, “Methods Overview” section).
Worked Example: Slides on an LMS
The most common scenario: your instructor uploads a PowerPoint deck to Canvas, Blackboard, Moodle, or a similar LMS. The slides sit behind a login page, but your audience (your marker, your classmates) can access them by logging in. That retrievability means you write a full reference list entry.
Here is a complete, correctly formatted example:
Smith, J. A. (2024, October 3). Introduction to cell biology: Structure and function [PowerPoint slides]. Canvas. https://canvas.university.edu
Parenthetical: (Smith, 2024)
Narrative: Smith (2024) explained that...
With slide number: (Smith, 2024, Slide 12)
Notice several precision details in that reference. The title uses sentence case: only the first word and any proper nouns are capitalized. The colon after the main title triggers capitalization of the next word (“Structure”). The format descriptor [PowerPoint slides] sits in square brackets after the title and before the period. The URL points to the Canvas login page rather than the specific file URL, because direct file links require authentication.
Worked Example: Publicly Available Slides
When a lecturer posts slides to a public platform like SlideShare or a public university course page without a login requirement, the format stays the same but the URL points directly to the slides.
Jones, P. R. (2023, March 14). Climate modelling methods: An introduction [PowerPoint slides]. SlideShare. https://www.slideshare.net/prjones/climate-modelling-intro
Because any reader can click that URL and verify the source, the retrievability criterion holds and no personal-communication treatment is needed.
Worked Example: Two Authors
Some lecture slide decks carry two instructors as co-authors. APA 7th edition lists both, separated by a comma and an ampersand.
Mack, R., & Spake, G. (2022, January 20). Citing open-source images and formatting references [PowerPoint slides]. Blackboard. https://blackboard.institution.edu
In-text, name both for the first citation: (Mack & Spake, 2022). For three or more authors, APA 7th edition uses only the first author's name followed by “et al.” for every citation, including the first.
When to Use Personal Communication Instead
The personal-communication rule exists because APA citations serve a verification function: readers should be able to find the source you cited. When that is impossible because the material lives behind a login no general reader holds, a full reference entry misleads rather than helps.
The Audience-Access Rule
According to APA Style's guidance on classroom and intranet sources (Publication Manual, 7th ed., Section 8.8), the test is your audience, not the slides themselves. If you are submitting an assignment inside the same course, your markers share your LMS access and a full reference entry works. If you are submitting to a journal, presenting at a conference, or writing for any reader who does not share your institutional login, those slides become inaccessible and personal communication applies.
A common situation where this matters: you are writing a literature review that will be published, and the most recent evidence comes from a lecture your supervisor delivered. That lecture exists as a slide deck on your university's Moodle page. Journal readers cannot access Moodle. Cite it as personal communication.
Personal Communication Format
Personal communications are cited in-text only. They never appear on the reference list because there is nothing for a reader to retrieve. The in-text format gives the communicator's initials and last name, the label “personal communication,” and the date as precisely as you have it (month, day, and year):
(J. A. Smith, personal communication, October 3, 2024)
Or in narrative form: J. A. Smith (personal communication, October 3, 2024) explained that...
One of the most common APA errors students make is adding a personal communication to the reference list. Personal communications belong only in the text. If a marker sees it on your reference page, that is a formatting error, regardless of how useful the content is.
Edge Cases: No Author, No Date, Video Lecture
Real lecture materials do not always arrive with every field neatly filled in. Three edge cases come up repeatedly, and each has a clear APA solution.
No Named Author
When slides carry no instructor name (for example, a department-produced slide set or a template with no byline), move the title to the author position. The title takes the place of the last name in both the reference list and in-text citations.
Introduction to organic chemistry: Functional groups [PowerPoint slides]. (2023, September 5). Blackboard. https://blackboard.university.edu
In-text, use a shortened title in double quotation marks: (“Introduction to Organic Chemistry,” 2023). Capitalize major words in the shortened title even though the full title uses sentence case.
No Date on the Slides
When you cannot determine when the slides were created or posted, use “n.d.” (no date) in the date position. This follows the same rule as any undated APA source.
Smith, J. A. (n.d.). Protein synthesis and transcription [PowerPoint slides]. Canvas. https://canvas.university.edu
In-text: (Smith, n.d.). If you cite multiple undated works by the same author, add lowercase letters to distinguish them: (Smith, n.d.-a) and (Smith, n.d.-b).
Recorded Video Lecture
A recorded lecture hosted on YouTube, Vimeo, or a public institutional media player uses the audiovisual format, not the PowerPoint slides format. The instructor becomes the author using their real name (not a username if the real name is known), with the channel name in brackets:
Smith, J. A. [Dr Smith Lectures]. (2024, October 3). Cell biology lecture 4: Membrane transport [Video]. YouTube. https://www.youtube.com/watch?v=example
If the video lecture comes with a separate downloadable slide file, cite the video and the slides as two distinct sources. Do not merge them into one reference. The full guide on how to cite YouTube videos in APA covers every variant of the video lecture format.
| Scenario | Format to use | Reference list entry? |
|---|---|---|
| Slides on LMS, audience has login access | Full reference entry | Yes |
| Slides on LMS, audience has no access | Personal communication | No |
| Publicly available slides (SlideShare, public page) | Full reference entry | Yes |
| No instructor name on slides | Title in author position | Yes |
| No date on slides | Use n.d. in date position | Yes |
| Recorded video lecture | Audiovisual format [Video] | Yes |
| Your own handwritten lecture notes | Personal communication | No |

Common Mistakes With APA Lecture Slide Citations
Referencing is a precision task and a single formatting error can cost marks or trigger a plagiarism query. These are the mistakes that appear most often in student submissions.
Using title case instead of sentence case
APA 7th edition uses sentence case for titles in reference list entries. Only the first word, proper nouns, and the first word after a colon are capitalized. "Introduction to Molecular Biology: Structure and Function" is wrong in a reference list. "Introduction to molecular biology: Structure and function" is correct.
Omitting the format descriptor
Forgetting [PowerPoint slides] after the title is a common omission. Without it, the reader does not know the source is a slide deck rather than a journal article or book. The brackets are not optional in APA 7th edition for this source type.
Using a direct deep link instead of the login URL
LMS file links include session tokens or require authentication. Any reader clicking the link gets an error or a login redirect. APA guidance specifies the home page or login URL instead, so readers at least reach the platform and know where to look.
Adding personal communications to the reference list
Personal communications never appear on the reference list. This is a frequent error for students who know they used the material and want to acknowledge it properly. The acknowledgement belongs in the in-text citation, not the reference list.
Treating lecture notes and slides as identical source types
Notes you write during a lecture belong to you and cannot be retrieved by anyone else: they are personal communication. The instructor's uploaded slide deck is a separate, independently existing document. Cite the slide deck as a file, not as your notes about the lecture.
Formatting citations by hand introduces errors. The university citations hub gives you a generator that applies APA 7th edition rules automatically. Run your references through it, then verify the output against the examples in this guide before submitting.

The APA Style site carries worked examples for over 100 source types, all verified against the 7th edition Publication Manual.
One format question that comes up alongside lecture slides is how to handle Google Slides or PDF exports of a presentation. If your instructor shares a Google Slides deck via a public link, treat it the same as public PowerPoint slides: use the title, [Google Slides], the platform name (Google Slides), and the direct URL. If they share a PDF export of their slides, follow the format for the document type the PDF represents. A PDF of lecture slides is still a set of lecture slides, so [PDF] or [PowerPoint slides converted to PDF] both work. The guide on how to cite a book in APA covers similar format-first principles for deciding which bracket descriptor to use.

Key Takeaways
- To cite lecture slides in APA 7th edition, use: Author, A. A. (Year, Month Day). Title in sentence case [PowerPoint slides]. LMS Name. Login URL.
- The in-text citation follows standard author-date format: (Smith, 2024). Add the slide number for direct quotes: (Smith, 2024, Slide 7).
- Slides on a password-protected LMS still require a full reference entry if your audience can log in and retrieve them. Use the LMS home page URL, not a direct file link.
- When your audience cannot access the slides at all, treat them as personal communication: cite in-text only as (A. A. Instructor, personal communication, Month Day, Year) with no reference list entry.
- For slides with no author, move the title to the author position. For slides with no date, use n.d. For recorded video lectures, switch to the audiovisual [Video] format.
- The three most common errors are title case instead of sentence case in the title, omitting [PowerPoint slides] after the title, and adding personal communications to the reference list.
- Your own handwritten lecture notes count as personal communication. The instructor's uploaded slide deck is a separate, independently citable document.
