In 2006, IntraHealth International, as implementer of the USAID-funded Capacity Project, developed and launched the HRH Global Resource Center, a digital library committed to reducing access barriers in developing countries to the best human resources for health information available. Since the launch, the HRH Global Resource Center has transformed in response to usage, feedback, and changes in the field. This article in Knowledge Management for Development shares IntraHealth’s experiences developing, using, and refining monitoring and evaluation methods and metrics for the HRH Global Resource Center.
