A changing landscape.

Open-access publication is inarguably valuable to science and to the public, yet skepticism about the long-term sustainability of open-access publications persists (see Nature, October 9, and Science, October 24). While some fear the effects of the open-access model—which shifts revenue streams from subscription fees to publication fees—on scientific societies and others, support for open access among funders is already increasing. Funding agencies that have announced policies supporting open access include the Howard Hughes Medical Institute and the Wellcome Trust (the largest private biomedical research funders in the United States and the United Kingdom, respectively) and, more recently, the Max Planck Institute, the Centre National de la Recherche Scientifique (CNRS), and other European agencies.
