Copyright laws protect a creator's intellectual property rights.  Copyright laws apply to web content, books, journals, magazines, images, photos, videos, etc. Copyright laws for educational usage are somewhat different than rules for commercial usage, and instructors should understand them before using copyrighted content. 

The University Libraries provides resources to help you use copyrighted materials legally.
