An university professor put a few journal articles on reserve in the digital library and makes them assigned reading for the class. Unfortunately, some students in the class complain that they dont have access to the Digital Library. The professor scans them and posts them on the Black Board. The professor gives the students in the class the permission they need to access the articles.

Discuss this scenario based on the four factors of fair use of copyrighted materials need to be considered to evaluate the professor action?
