How do I cite a PowerPoint presentation in MLA citation style?
To answer your question, I consuted the OWL at Purdue MLA Guide, which can be found via the UHD Library's Citing and Writing research guide at http://library.uhd.edu/mla. Unfortunately, there is no specific instructions on PowerPoint presentations. However, I found general guidelines on citing digital files:
Digital Files (PDFs, MP3s, JPEGs)
Determine the type of work to cite (e.g., article, image, sound recording) and cite appropriately. End the entry with the name of the digital format (e.g., PDF, JPEG file, Microsoft Word file, MP3). If the work does not follow traditional parameters for citation, give the author’s name, the name of the work, the date of creation, and the medium of publication. Use Digital file when the medium cannot be determined.
