What if you want to share your work with colleague or students?
Accordingly, authors should take care to assign the rights to their work in a manner that permits them and their students and colleagues to use their work in teaching, research and other purposes. Transferring copyright doesn’t have to be all or nothing. Publishers only need the right of first publication, not a wholesale transfer of copyright. So, a compromise is often desirable, which authors can accomplish through an appropriate addendum.
