CHORUS (the Clearinghouse for the Open Research of the United States) has partnered with a number of federal agencies over the past six months to help them comply with the Office of Science and Technology Policy (OSTP) and Office of Management and Budget (OMB) directives requiring open access to federally funded research. The United States Department of Energy (DOE), the Smithsonian Institution, the National Science Foundation (NSF), the U.S. Geological Survey (USGS), and U.S. Commerce Department’s National Institute of Standards and Technology (NIST) have all reached agreements with CHORUS.
