This report summarizes the main points of discussion of a national workshop convened to advance knowledge and practice for ethics in science and engineering. Following the enactment of the America COMPETES Act and its provisions to increase attention to ethics and the responsible conduct of research in science and engineering, the National Science Foundation (NSF) supported two beta site projects to advance understanding of the key dimensions required for a national online clearinghouse in ethics for science and engineering. The ESENCe Beta Site project, based at UMass Amherst and one of two such beta sites in the United States, thanks the participants of a national workshop held in October 2009 in Amherst, Massachusetts. Workshop participants were carefully selected and invited based on their expertise in library and information science, in ethics in science and engineering, and in related social sciences. More information about the workshop is available through the project website www.umass.edu/sts/esence.
