I used a number of copyrighted pictures under fair use to produce a work. I have now found a publisher who will be paying me royalties. As I understand it, an original work is automatically copyrighted once it is fixed in a tangible medium, i.e. published.
Some faculty members are interested in having their publications on-line.
I use parts of a video for a class that I regularly teach. I had a commercial television program taped last semester which I had planned to use in my class this semester. When I try to copy software from the Applications Server to use at home, some of the products don't work. Not only do licenses vary from vendor to vendor but also from release to release. Infringement is encroachment on or violation of the rights of authors or publishers.
