"What Is Fair Use?
Fair Use refers to the right to use a copyrighted work without the copyright owner’s permission. In this context, “use” might mean to make a copy or photocopy, to paraphrase, to quote, to record, etc. Such usage is exempt from the copyright holders' granted rights.
Educational or research usage typically falls under Fair Use, especially in the traditional face-to-face classroom environment. There are additional exemptions in Section 110 specifically for a distance learning environment ...
