Systematic / Systemic bias in bibliometics

I'm looking for work or discussions on systematic bias in
bibliometrics or appropriate fora where such discussions are likely to
happen. Even critical analysis of the founding assumptions of
bibliometrics as a field would be a good place to start

I have some ideas but they seem obvious and I'm afraid I'm missing a
community of practice because what I think of as a widget they know as
a whatzit.

cheers
