Copyright can be confusing.
Creative Commons doesn't replace copyright, it is stands on copyright law and offers additional types of permissions. In most cases, material retains its copyright for 95 years from publication or 120 years from creation whichever is shorter. Or if we know the identity of the author, the term is the author's life plus 70 years. Creative Commons materials retain their license in perpetuity and cannot be revoked.
Public domain, of course, no longer has a copyright on it.

Most faculty members would have been aware of assigning a copyright to a publisher, but this was typically an inconsequential act. Today copyright has complicated ramifications throughout academic life.
You probably have an intuitive understanding of copyright's importance in the creation and distribution of creative works -- books, journal articles, electronic publications, music, movies, software, artworks, and sculpture. And you probably are aware that when you make and distribute copies of others' works to your students, or to research colleagues, it may or may not be a fair use. And most of us by now know that massive public distribution of copyrighted works without the owners' permission is illegal. But these uses barely dip a toe in the waters.
The role of copyright in the flow of research is undergoing dramatic and exciting change. The options for scholarly communication have never been broader or more effective. You'll find discussion of copyright woven all through important aspects of research and teaching, such as:
Copyright both enables us and it throws stumbling blocks in our path.
