Communication (note - it's NOT spelled with an "s" at the end) encompasses bachelor's and master's programs of study in Public Relations, Journalism, Electronic Media, and Human Communication. This page has brief info on finding articles and books on those subjects. If you get a complicated question, don't hesitate to contact the liaison to the Department of Communication, Steve Hardin.
You're most likely to encounter Communication students who are doing assignments for COMM 101. They must develop and perform informative speeches and persuasive speeches. There's already a separate LibGuide for this class if you need more detailed info.
