Code of Best Practices in Fair Use for Scholarly Research in Communication
The International Communication Association's Code of Best Practices in Fair Use for Scholarly Research in Communication, which is posted at the American University's Center for Social Media site (as well as it's own), identifies four situations that represent the current consensus within the community of communication scholars about acceptable practices for the fair use of copyrighted materials." The Center for Social Media is the place to go for fair use issues in education and media production. You can view videos on codes for best fair use practice in user-generated video, documentary film making, media literacy, and remix culture.
On the same front, just yesterday the Librarian of Congress announced the latest ruling on exemptions to the Digital Millennium Copyright Act, expanding fair use practice to include encrypted copyrighted works. Teachers, students and filmmakers can now break encryption to quote limited portions of copyrighted works into their own work or teaching.
