The Center for Social Media at American University has released Clipping Our Own Wings Copyright and Creativity in Communication Research.
Here's an excerpt from the announcement:
A survey of communication scholars' practices, conducted by the Ad Hoc Committee on Fair Use and Academic Freedom in the International Communication Association (ICA), reveals that copyright ignorance and misunderstanding hamper distribution of finished work, derail work in progress, and most seriously, lead communication researchers simply to avoid certain kinds of research altogether.
Nearly half the respondents express a lack of confidence about their copyright knowledge in relation to their research. Nearly a third avoided research subjects or questions and a full fifth abandoned research already under way because of copyright concerns. In addition, many ICA members have faced resistance from publishers, editors, and university administrators when seeking to include copyrighted works in their research. Scholars are sometimes forced to seek copyright holders' permission to discuss or criticize copyrighted works. Such permission seeking puts copyright holders in a position to exercise veto power over the publication of research, especially research that deals with contemporary or popular media.
