Center for Social Media (American University)
There are a lot of places to go to keep up on fair use practice but American University's Center for Social Media is one of the best. However, the Center has a wider purpose:
The site prides itself on being a resource to teachers and media/content makers/creators. One can find and download codes of best practices for Academic and Research Libraries, OpenCourseWare, Media Literacy Education, and Online Video; there's even a Code of Best Practices in Fair Use for Poetry. They also have a collection of Fair Use videos (ex. Did These Mashups Use 'Fair Use'? You Decide!; Fair Use in Documentary Film Discussion Clips; and Remix Culture).
The Center for Social Media showcases and analyzes media for public knowledge and action—media made by, for, and with publics to address the problems that they share. We pay particular attention to the evolution of documentary film and video in a digital era. With research, public events, and convenings, we explore the fast-changing environment for public media. The Center was founded in 2001 by Patricia Aufderheide, University Professor in the School of Communication at American University.
If you are interested in making media that matters (i.e. propels viewers into action), documentary production and promotion, or media literacy/education in general this is a bookmark-worthy site.
