Consists of interviews with thirty-six particle physicists, conducted as background material for his book CONSTRUCTING QUARKS: A SOCIOLOGICAL HISTORY OF PARTICLE PHYSICS, published in 1984. Pickering sought to document the founding and growth of research traditions structured around the quark concept, therefore, almost all interviews focused upon the interviewee's overall research career rather than narrowly defined historical episodes. They cover the period from 1964 when the quark model was formulated to 1980 when quark theories had come to dominate research practice in high-energy physics. More specific topics include J/psi color models, Fairbank's fractional charges, and the Price magnetic monopoole. Participants include: Henry Abarbanel, Luis W. Alvarez, Barry Barish, A. O. Barut, John Bell, James Bjorken, Elliott D. Bloom, Gordon Feldman, Geoffrey Chew, Sidney Coleman, A. De Rujula, Sid Drell, John Ellis, P.G.O. Freund, Erwin Gabathuler, Mary Gaillard, H. Georgi, Gerson Goldhaber, Sheldon Glashow, Peter Higgs, Roman Jackiw, R. L. Jaffe, P. V. Langshoff, Ed Lofgren, Seymour Joseph Lindenbaum, Francis Eugene Low, Y. Nambu, Robert B. Palmer, and Hugh David Politzer, Charles Prescott, P. Buford Price, Chris Quigg, B. Richter, A. Salam, G. t'Hooft, and C. N. Yang.
