You can read more on the Edward Mellen Press “saga” (Disclaimer: This is how the law librarians’ blog describes the EMP litigation. Don’t Sue Me, Herb!) here.
My take on it is that we now have academics butting heads over power and control. Universities are, fundamentally, institutions that seek to maintain their role as gatekeepers and censors of information and thought. In the modern electronic world, they are losing. The result: vicious fighting amongst themselves.
The critics of Mellen seek to defend their traditional academic turf of bureaucracy, control and gatekeeping. EMP seeks control of the critics by way of silencing them. A pox on both your houses.
