Rafal Kasprowski has published "Perspectives on DRM: Between Digital Rights Management and Digital Restrictions Management" in the Bulletin of the American Society for Information Science and Technology.
Here's an excerpt:
This report of a panel session organized by the author at the 2008 Annual Meeting of the American Society for Information Science & Technology (ASIS&T) presents the DRM issue in four contexts: use restrictions in libraries, the anti-circumvention rules of the Digital Millennium Copyright Act (DMCA), commercial and academic licensing and DRM-free software alternatives. The four panelists were Kristin R. Eschenfelder, associate professor at the School of Library and Information Studies of the University of Wisconsin-Madison and recipient of multiple grants for her work on DRM; Kevin L. Smith, J.D., scholarly communications officer at Duke University and author of the highly regarded web log Scholarly Communications @ Duke; Bill Burger, vice president of marketing at the Copyright Clearance Center (CCC), a leading provider of content licensing solutions for corporations and academic institutions; and John Sullivan, operations manager at the Free Software Foundation, a nonprofit that promotes the development and use of free software and campaigns against DRM. The session was recorded in October 2008 and is complemented in this report with a 2009 update to the DMCA legislation.
