They haven’t yet, but they are supporting SOPA, a bill that attempts to roll back Web 2.0 by making it easy to shut down entire sites like wikipedia and craigslist if they contain any user-submitted infringing material. (Here is a hypothetical airline-oriented version of SOPA, with only a little hyperbole about planes in the air.)
I think that appealing to Elsevier’s love of open scientific discourse is misguided. Individual employees there might be civic-minded, but ultimately they have $10 billion worth of reasons not to let the internet drive the costs of scientific publishing down to zero. Fortunately, their business model relies on the help of governments and academics. We can do our part to stop them by not publishing in, or refereeing for, their journals (the link describes other unethical Elsevier practices). Of course, this is easy to say in physics, harder in computer science, and a lot harder in fields like medicine.
There is another concrete way to stand up for open access. The White House Office of Science and Technology Policy has requested comments on the question of public access to federally-funded scientific research. Comments should be from “non-Federal stakeholders, including the public, universities, nonprofit and for-profit publishers, libraries, federally funded and non-federally funded research scientists, and other organizations and institutions with a stake in long-term preservation and access to the results of federally funded research.” That’s us!
But don’t procrastinate. The deadline for comments is January 2.
Here is more information, with instructions on how to comment.
Here is also the official government Request For Information with more details.
