A rich and diverse set of potential bibliometric and scientometric predictors of research
performance quality and importance are emerging today-from the classic metrics (publication
counts, journal impact factors and individual article/author citation counts) to promising new online
metrics such as download counts, hub/authority scores and growth/decay chronometrics. In and of
themselves, however, metrics are circular: They need to be jointly tested and validated against what
it is that they purport to measure and predict, with each metric weighted according to its contribution
to their joint predictive power. The natural criterion against which to validate metrics is expert evaluation
by peers; a unique opportunity to do this is offered by the 2008 UK Research Assessment Exercise,
in which a full spectrum of metrics can be jointly tested, field by field, against peer rankings.
