I would recommend as an instructor to be aware of the laws and resources to rely on for current
information surrounding copyright and fair use before providing documents online or in a classroom. In
the education field most copyright holders are willing to work with instructors to use their material. Asking
permission directly to the copyright holder and getting written permission is the best way to avoid any
issues.
Creative Commons is another way an instructor can use valuable materials for instruction. This is a
short guide that includes symbols relating to how the work can be used. This is an easy simple way
material can be accessed and used in an educational setting. The creative commons link describes how
and which documents can be used in a simple format.
