Whatever the format, citations provide evidence that your statements are reasonable and believable. When giving a presentation or speech, though, you can't just read out parenthetical citations like you'd write in a paper.

Works Cited
"Tallest Buildings." Council on Tall Buildings and Urban Habitat, https://www.skyscrapercenter.com/buildings. Accessed 14 February 2025.
It would sound weird to say out loud, "According to 'Tallest Buildings,' the Burj Khalifa..."
It gets better if we say "According to the article 'Tallest Buildings,'..." but the organization in this case is the more interesting entity to name out loud. Your audience can read the less interesting citation on your slide.
