How to Cite Sources on Presentation Slides
Good presentations show where their facts come from. Here is a simple way to cite your sources on slides without crowding them.

Why cite on slides?
Citing your sources shows that your information is reliable, gives credit to the people who created it, and helps your teacher or audience check your facts. Many schools and colleges also require it. Always check your own assignment instructions, because your teacher may ask for a specific citation style.
Step 1: Keep track while you research
Write down the author, title, website or publisher, date and link every time you use a fact, quote, number or picture. It is much harder to find sources again later. A simple list in a document is enough.
Step 2: Use a short citation on the slide
When a slide includes a fact, a statistic, a chart or a quote, add a short citation in small text at the bottom of that slide. The exact format depends on your required style, but it is usually something like the author and year, for example "(Author, Year)", or the name of the organisation that published the data. Do not put the full reference on every slide. The short version points to the full one at the end.
Step 3: Add a references slide at the end
On your last content slide, list the full details of every source you used. Follow the style your teacher asks for, such as APA, MLA or Harvard. A simple pattern, which varies by style, is:
- Author or organisation
- Year of publication
- Title of the page, article or book
- Publisher or website name
- Link (for web sources)
Use the official guide for your style to format each item correctly. Many university and school library websites have clear examples.
Step 4: Credit pictures and charts
Images need credit too, even free ones. A short line such as "Photo by [photographer name] on [website]" under the picture, or on your references slide, is a good habit. Many free photo sites do not legally require credit, but it is polite and often expected in schoolwork. If you made a chart from someone else's data, name the source of the data.
Step 5: Quote carefully
- Put exact words in quotation marks and name the speaker or author.
- Keep quotes short. Explain the idea in your own words instead of copying paragraphs.
- Even when you paraphrase, you still need to cite where the idea came from.
Common mistakes
- Writing "Source: Google" or "the internet". Name the actual website or author.
- Citing only at the very end, so no one knows which fact came from where.
- Copying text from a website and only changing a few words.
- Trusting an AI tool as a source. AI can make mistakes, and it sometimes invents references. Always find and read the original source yourself before you cite it.
SlideMate's slides are a draft and its "Further reading" suggestions only point you toward where to look. They are not a checked list of sources. Before you hand in your work, find real sources for your key facts and cite them yourself. If you are working from notes, see our guide on turning research notes into slides.
