When uploading content to your course shell, it's important to adhere to copyright laws. The concept of "Fair Use" is not blanket permission to use all content in your course. Text, images, videos, and audio files can all be subject to copyright protections.
It is your responsibility as the course instructor to comply with copyright laws.
For more information, see the College of DuPage Library's Copyright Guide. The guide includes a number of resources on how to ensure you are within the guidelines of Fair Use, or if you need to request permission to use copywritten material in your courses.
