Author and Reviewer Pledge It is with great sadness about the current state of scientific publishing that I make this resolve.
As of 1 January 2012, I will not submit research papers to, or review research papers for, any journal or book published by those organizations whose efforts have come to my attention to either: (1) reduce the current level of public access to the fruits of publicly funded research for their own profit or (2) use harsh "journal bundling" contracts to extract exorbitant fees from libraries. These organizations include: Ecological Society of America (web site), Elsevier B. V. (web site), Springer (Part of Springer Science+Business Media)
Letter from Ecological Society of America (dated 20th December 2011 in response to the U.S. Office of Science and Technology Policy ), with its bizarre suggestion that authors write a second version of each abstract	Michael Eisen's blog (5th January 2012) about efforts to alter US legislation to allow publishers to increase their profit from publicly funded research	Interview by Josh Fischman, published in the Chronicle of Higher Education, with Alicia Wise, Elsevier's Director of Universal Access. Ms Wise is quoted as claiming that the metadata added to articles by Elsevier, have "changed the way research is done today" and made it "more efficient", and that this justifies their journal prices.
