More on how OA supports metrics (and metrics support OA)

Stevan Harnad, Citation Statistics: International Mathematical Union Report, Open Access Archivangelism, June 15, 2008. 

Summary:  The IMU's cautions are welcome: Research metrics do need to be validated; they need to be multiple, rather than a single, unidimensional index; they need to be separately validated for each discipline, and the weights on the multiple metrics need to be calibrated and adjusted both for the discipline being assessed and for the properties on which it is being ranked. The RAE 2008 database provides the ideal opportunity to do all this discipline-specific validation and calibration, because it is providing parallel data from both peer panel rankings and metrics. The metrics, however, should be as rich and diverse as possible, to capitalize on this unique opportunity for joint validation. Open Access not only provides more metrics, but it increases them, as well as providing open safeguards against manipulation and misuse.
