One of the limitations on copyright is the “Fair Use” doctrine, which can be found in section 107 of the copyright law. This broad and flexible doctrine provides instances for when using copyrighted material may be deemed fair. Each factor must be weighed in determining if fair use applies.
Another important factor in fair use is to consider if your use may be transformative. In other words, is your use of the work substantially different from the original intention of the work?
The Association of Research Libraries (ARL) created the Code of Best Practices in Fair Use for Academic and Research Libraries (PDF), a clear and easy-to-use statement of fair and reasonable approaches to fair use developed by and for librarians who support academic inquiry and higher education.
