[9.04] The NASA Astrophysics Data System: Bibliometrics Investigations

M.J. Kurtz, G. Eichhorn, A. Accomazzi, C.S. Grant, S.S. Murray (Harvard-Smithsonian CfA)

Traditional bibliographic measures heve centered on the use of citations to measure the productivity of individuals and organizations. The ADS is perhaps the first entity which is capapable of analyzing the entire research output of a scientific discipline based on a fair sample of scientists using the readership rate of scientific papers.

We demonstrate the similarities and differences between reads and cites; we show that both are measures of the same thing, the usefulness of an article. We thus prove that the normative theory of citations is true in the mean. We develop a productivity measure using reads and cites which is substantially less age biased than cites alone.

The ADS is funded by NASA under grant NCC5-189
