In an earlier SSRC-supported study (grant number HR7448), a considerable amount of bibliometric (that is, publication and citation) data was produced for all the main experimental high-energy physics facilities worldwide over the period 1961-82. The purpose of the ESRC-funded project reported here was two-fold: (1) to extend the period covered up to the end of 1984, thereby bringing in the major discoveries of the W and Z particles made by CERN (the European Particle Physics Laboratory) in 1983; (2) to computerize the data for the period 1961-84, and produce programs for analyzing the results that could be utilized by sociologists of science in undertaking secondary analysis.
