Lectures, guest talks, and class notes need careful attribution. Learn the exact format for APA 7th edition and MLA 9th edition, with worked examples for live, recorded, and posted slides.
Fill in the lecture details below to generate a formatted citation.
Lectures are considered personal communications in some contexts, but if they are recorded, posted online, or part of an institutional course, they become citable sources. The key information is always the same:
Scenario: You attended a guest lecture by Dr. Patricia Chen on "Climate Justice in the Global South" at the University of Toronto on September 15, 2023, in Room 204 of the Environmental Centre.
Scenario: Professor James Liu recorded a lecture for PSYC 201 titled "Cognitive Biases in Decision-Making" and posted it to the course learning management system on October 22, 2023. The video is at https://lms.university.edu/courses/psyc201/videos/wk5.
Scenario: Dr. Rachel Torres posted the PowerPoint slides for her lecture on "Molecular Genetics" for BIO 301 on the course website on March 8, 2024. The file is available at https://biology.university.edu/courses/bio301/slides/molgen.
Here is how APA 7 and MLA 9 differ for lectures:
| Element | APA 7 | MLA 9 |
|---|---|---|
| Author/Speaker | Last, F. (initial only) | Last, First |
| Date | (Year, Month Day) | Day Month Year (no parentheses) |
| Title | Sentence case, no quotes | "Title in quotation marks" |
| Format | [Lecture] or [PowerPoint slides] | Lecture. or Lecture video. or PowerPoint presentation. |
| Institution | Institution name, Location | Institution Name (after date) |
| URL | https://... (if applicable) | https://... (if applicable, at end) |
In APA 7, unpublished lecture notes from a class you attended are usually treated as personal communications and excluded from the reference list — cite them in the text only with the date and author's name (e.g., "According to Dr. Smith's lecture notes (personal communication, September 15, 2023)…"). In MLA 9, you can cite them as a class lecture with the course name and institution. If the notes are posted online, both styles now allow a full reference.
Use the guest speaker's name as the author, the title of the lecture in quotation marks, the course or event name, the date, the institution, and the format descriptor "Guest lecture." or "Lecture." Example: Smith, John. "Immigration Policy in Crisis." Comparative Politics Seminar, 20 Oct. 2023, Harvard University, Cambridge, MA. Guest lecture.
Yes. An in-person lecture has no URL; APA uses the institution and location. A recorded lecture requires a URL (or video platform link). In APA, add [Lecture video] or the URL. In MLA, add the URL at the end. If the recording is only available to students in the course, note the institution name clearly so others can request access.
Treat PowerPoint slides as a published presentation. APA: Author, A. (Year). Title [PowerPoint slides]. Retrieved from URL. MLA: Author, First. "Title." Course/Event, Date, Institution. PowerPoint presentation, URL. This is one of the most common citation needs for students and both styles handle it directly now.
Cite it as a recorded lecture. APA: Speaker, A. (Year, Month Day). Title [Lecture video]. Institution. URL. MLA: Speaker, First. "Title." Course Name, Date, Institution. Lecture video, URL. Include the Zoom link if it remains publicly accessible; if it expires or is password-protected, note that fact.
APA 7 requires initials only (first initial + middle initial if available). MLA 9 uses the full first name if known. Check your source material — if the speaker's middle name is not published or announced, use only the first and last name.
