The guide, "Code of Best Practices in Fair Use for Online Video," is available free http://www.centerforsocialmedia.org/resources/publications/fair_use_in_online_video/.
Developed by the Center for Social Media, part of the School of Communication at American University, this document is a "code of best practices that helps creators, online providers, copyright holders, and others interpret the copyright doctrine of fair use."
"It is important for video makers, online service providers, and content providers to understand the legal rights of makers of new culture, as policies and practices evolve. Only then will efforts to fight copyright “piracy” in the online environment be able to make necessary space for lawful, value-added uses."
