Page 187 On hyper authorship
"hyper authorship” is an indicator of "collective cognition" in which the specific contributions of individuals no longer can be identified. Physics has among the highest rates of coauthorship in the sciences and the highest rates of self archiving documents via a repository. Whether the relationship between research collaborators (as indicated by the rates of coauthorship) and sharing publications (as reflected in self archiving) holds in other fields is a question worth exploring empirically.
