In recent years researchers in the Performance Indicators Project at t
he Australian National University have undertaken a number of projects
involving collaboration with colleagues in England or attempts to rep
licate results obtained by others. All projects have necessitated clos
e scrutiny of the methodologies previously used or to be used and have
made clear the urgent need for comparable standards. In this paper we
have focused on two projects: one, an analysis of Australia's shares
of publications and citations, where we sought to learn from the debat
e on methodology that surrounded the question of decline in British sc
ience; the second, an analysis of astronomy publications in Australia
where we sought to replicate methodology used in a previous European s
tudy.
