CMST 220 Public Speaking

This guide is to help you find good topics and evidence for your Informative or Persuasive/Position speeches in CMST& 220: Public Speaking.

Types of Sources You Can Use


Articles can include news, scholarly (peer-reviewed) research, or data and analysis of your topic.

Videos & DVDs 

Videos and DVDs include both streaming online video and physical DVDs at the library. These are great sources for images, interviews, and (sometimes) statistics.

Books & eBooks

Books are a good source for connecting your topic to the "larger picture" by bringing in history or the social context (why your topic is important, etc.). You don't have to read the entire book to have it as a source-- you can use a smaller part of it if you like.
