That said, here are some copyright resources in which we should be aware. I not only keep these available for the times I may need my own clarification, but I like sharing these links with SMEs, eLearning designers and anyone else who may need them.
Copyright.gov (US Copyright Office)
Copyright Basics (US Copyright Office)
Copyright Basics (BYU)
Q&A - Copyright and Fair Use (Library of Congress)
Internet Copyright Infringement (Infographic)
And you can find more in my DIIGO "Copyright" bookmarks.
