How to Cite a Lecture or PowerPoint in MLA, APA & 5 More Styles
A lecture is one source that can reach you four different ways — a live talk you sat through, a slide deck on Canvas, a PowerPoint on the open web, a Zoom recording — and each way changes the citation. Worse, the two major styles disagree at the root: MLA gives an unrecorded lecture a full works-cited entry, while APA says an unrecorded lecture is a personal communication that never appears in the reference list at all. Most of the confusion around citing “my professor’s PowerPoint” is really confusion about which of these situations you are in. This guide sorts them out, with the official MLA and APA templates and the same real slide deck rendered in all seven styles the site supports.
The shortest answer: in MLA, slides your class can retrieve are cited like any material posted to a website — presenter’s name, the deck title in italics, the site or LMS name in italics as the container, the date posted, and the URL, with “PowerPoint presentation.” added at the end if the format matters. A live lecture gets its title in quotation marks instead, followed by the event or course name, the date, and the venue. In-text, cite the last name alone: (Carson), or (Carson, slide 4) if the slides are numbered.
What counts as a lecture or PowerPoint
For citation purposes, this page covers a talk delivered to an audience (a class session, a conference paper, a guest lecture, a webinar) and the slides that accompany one (PowerPoint, Google Slides, Keynote, Prezi), wherever they are posted — an LMS like Canvas or Blackboard, SlideShare, a course website, a company intranet.
Several nearby sources cite better as something else:
- A lecture recorded and posted to YouTube (or a public Zoom link) cites as a YouTube video or online video — the recording is the retrievable object, not the live event.
- Slides exported to PDF and posted as a reading still cite as slides, but a syllabus, article scan, or handout on Canvas is closer to a PDF citation with its own author and date.
- A study your professor summarized on slide 12 should be cited from the original. APA is explicit: if the slides cite information published elsewhere, it is best to find, read, and cite the original source yourself.
- A conversation during office hours is not a lecture; it is handled like other unpublished personal communications.
Cite the lecture or the deck itself when it is the actual source of the idea: your professor’s own framework, an original synthesis, a claim made from the podium.
Information to collect before you cite
Open the deck or your syllabus and pin down:
- The presenter’s name — and whether the presenter actually wrote the slides. MLA warns against assuming the instructor is the author; instructors often upload decks they did not create.
- The title — of the deck or the lecture, exactly as given. If the lecture had no announced title, a short description will stand in.
- The course or event name — “MLA Annual Convention,” “BIO 201,” a conference session.
- The site or LMS name — Canvas, Blackboard, Moodle, SlideShare, the department site.
- The date — for posted slides, the date they were made available to the class; for a live lecture, the date it was delivered.
- The URL — for open-web slides, the full URL; for APA citations of LMS material, the login-page URL rather than the deep link.
- Slide numbers — only if you will cite a specific slide.
The generator at / extracts most of these fields from a pasted URL when the slides live on the open web. For Canvas and Blackboard material, expect to fill in the presenter and date by hand — LMS pages hide their metadata behind the login.
The same slides in all seven styles
The example below is the worked example from APA Style’s official “PowerPoint slide or lecture note references” page: a real, publicly retrievable SlideShare deck by literacy educator Jen Jones.

Two structural decisions split the styles. The first is whether the deck is a standalone work. MLA and APA both say yes and italicize the title — MLA in title case, APA in sentence case. Chicago and the numeric styles treat it like an ordinary web page, with the title in quotation marks or roman type.
The second is where the format is recorded. APA puts [PowerPoint slides] in brackets straight after the title; that bracket is part of the official template, not decoration. MLA allows “PowerPoint presentation.” as an optional supplemental element at the end of the entry. Vancouver falls back on its generic [Internet] label, and the rest say nothing about format at all.
The in-text citation for the same deck, with slide 7 cited specifically:
- MLA: (Jones) — or (Jones, slide 7) when the slides are numbered
- APA 7: (Jones, 2016) in parentheses, Jones (2016) narratively; with the slide, (Jones, 2016, slide 7)
- Chicago author–date: (Jones 2016)
- Harvard: (Jones, 2016)
- Vancouver, AMA: the entry’s number, e.g. superscript ⁵
- IEEE: [5]
How to cite a lecture or PowerPoint in MLA
MLA has two patterns, depending on whether you used posted slides or attended a live talk.
Slides posted to an LMS or website. The MLA Style Center’s instruction is to cite a slide presentation uploaded to a learning management system “the same way you would cite any material posted to a website,” following the MLA format template:
Author’s Last Name, First Name. Title of the Presentation. Site or LMS Name, uploaded by Name, Day Month Year, URL. PowerPoint presentation.
MLA’s own example:
Carson, Sandy. Introduction to Digital Humanities. Blackboard, uploaded by Carson, 20 Oct. 2019, blackboard.ucla.edu/. PowerPoint presentation.
Note the details: the deck title is italicized as a standalone work, the LMS name is italicized as the container, the URL drops https://, and the format note at the end is an optional supplemental element — include it when knowing the source was a slide deck helps your reader.
A live lecture, talk, or class session. The title goes in quotation marks, followed by the event or course name (in roman type), the day-month-year date, and the venue — or the word “online” for a virtual session. MLA’s example, from a 2026 convention paper:
Nazir, Komal. “Sensing Spices: Transcorporeal Resistance and Affective Assemblages in Mirch Masala.” MLA Annual Convention, 8 Jan. 2026, online.
In-text, MLA cites the last name only, since a lecture has no page numbers: (Nazir), (Carson). If the slides are numbered, point to the slide: (Carson, slide 4). The in-text citations guide covers how these combine with quotations.
The three variants most searchers need:
The instructor didn’t write the slides. MLA’s course-materials guidance warns against assuming the instructor is the author. If the deck names its real author, that name takes the author slot, and the instructor who posted it can appear in the contributor element: “uploaded by [Instructor].” If no author is named anywhere, start the entry with the title.
Which date to use. MLA’s rule is to cite the date “most meaningful or most relevant to your use of the source.” For slides on Canvas, that is the date they were made available to your class — not the date in the deck’s footer, and not the semester’s start date.
A public online lecture. A talk published on the open web — a TED talk, a university’s public lecture series — takes the site as its container, as in MLA’s example: Allende, Isabel. “Tales of Passion.” TED: Ideas Worth Spreading, Jan. 2008, www.ted.com/talks/isabel_allende_tells_tales_of_passion/transcript?language=en.
How to cite a lecture or PowerPoint in APA
APA 7 (Publication Manual Section 10.14) splits the same territory a different way: what matters is whether your reader can retrieve the source.
Slides available on the open web. The template:
Author, A. A. (Year, Month Day). Title of presentation in sentence case [PowerPoint slides]. Site Name. URL
APA’s official example is the deck in the table above:
Jones, J. (2016, March 23). Guided reading: Making the most of it [PowerPoint slides]. SlideShare. https://www.slideshare.net/hellojenjones/guided-reading-making-the-most-of-it
Slides on Canvas, Blackboard, or an intranet. If you are writing for an audience with access to the site — a class paper, an internal report — provide the LMS name and its URL, and APA is specific that a login-protected site gets its login-page URL, not the deep link that only works inside your session. The official example:
Mack, R., & Spake, G. (2018). Citing open source images and formatting references for presentations [PowerPoint slides]. Canvas@FNU. https://fnu.onelogin.com/login
If your audience does not have access to the LMS, the slides are unretrievable to them, and APA reclassifies the source as a personal communication.
An unrecorded live lecture. This is the sharpest MLA–APA split. APA (Section 8.9) treats unrecorded classroom lectures and live speeches as personal communications: cited in the text only, with no reference list entry, because no reader can go back to them. Narrative form: E.-M. Paradis (personal communication, August 8, 2019). Parenthetical: (T. Nguyen, personal communication, February 24, 2020).
In-text for retrievable slides, APA is standard author–date: (Jones, 2016) or Jones (2016), adding a slide number for a specific slide: (Jones, 2016, slide 7).
Two variants worth knowing. Decks made in other software change only the bracket: [Google Slides], [Prezi slides]. And if the slides summarize published research, APA’s advice is to skip the slides entirely — find, read, and cite the original study.
Edge cases: notes, Zoom, guest speakers
Your own class notes. MLA is blunt about this one: if you took notes on a lecture and refer back to them in a paper, do not cite your notes — cite the presentation itself as the source of the information. Build the entry from the lecture’s details (speaker, title, course or event, date, venue). APA reaches the same practical outcome by another route: the underlying lecture was unrecorded, so it is a personal communication, in text only.
A recorded Zoom lecture. If the recording is posted somewhere your reader can reach — the course site, YouTube, a department page — cite the recording as an online video, with the date of the session and the recording’s URL. If the recording was never shared or the link has expired, you are back to the live-lecture rules: a full MLA entry for the event, a personal communication in APA.
A guest speaker or conference talk. MLA uses the live-lecture format with the event name, as in the Nazir example above. APA gives conference sessions a full reference — speaker, dates of the conference, title, a bracketed description of the format, event name, and location — because conference programs make them documentable even without a recording.
No author on the deck. Check the first and last slides and the file’s properties before deciding. If the deck genuinely names no one, MLA starts the entry with the italicized title; APA moves the title into the author position. Never promote the course name into the author slot.
No date. MLA simply omits the date element. APA uses (n.d.) in both the reference and the in-text citation: (Hello Literacy, n.d.).
The deck was taken down after the semester. Cite what you used, with the date it was available to you. Since LMS content routinely disappears at term’s end, save your own copy of any deck you cite the day you decide to cite it — the citation documents what you consulted, but only your copy can prove what it said.
A final principle: retrievability decides everything. If your reader can get to the source — a SlideShare deck, a Canvas upload they can log into, a posted recording — give a full reference that points the way. If only you experienced it, MLA documents the event itself, while APA moves the citation into your text as a personal communication. Decide which situation you are in first, and the format follows.
