CHORUS has released the CHORUS Progress Report, April 2015.
Here's an excerpt:
As of this month, CHORUS is providing access to and information about tens of thousands of articles reporting on federally funded research. CHORUS was also named by the US Department of Energy as part of its public-access solution. The significant progress we've made in the eight months since we moved into full production mode is a great foundation for CHORUS to build on for the benefit of the scholarly community. This report is a summary of our achievements during this pivotal period.
