I know as a Librarian, we were taught that an institution may make ONE
copy of a copyrighted item for educational purposes only ( These are
called the Fair Use Guidelines). In order to USE the materials on a
cassette, you should probably copy it into another format as cassettes are
not long lived with regular use.
