Whether we like it or not, modern academia is increasingly being measured, in some vain attempt to get objective measures. Although it is unwise to fight 'being measured', it is at least possible to steer the measures away from meaningless ones, backed by peer-reviewed research that establishes this unrefutably.
There are a lot of different metrics that have been defined - I am not looking for those. What I want is pointers to the research behind the scientific validity of those metrics.
So the question is: where should I look for scientific assessments of bibliometrics?
