I would like to thank the speakers Drs. David Burke (SLAC), R. Palmer (BNL), S. Krinsky (BNL), G. Bauer (PSI, Switzerland) and K. McDonald (Princeton University), for their informative presentations and for providing copies of their transparencies and notes for inclusion in this Report. I also would like to thank Dr. N. Samios (BNL Director) for his participation and Welcome Address; and Drs. J. Sandweiss (Yale University), M. Blume (Deputy Director, BNL) and M. Schwartz (Associate Director of High Energy and Nuclear Physics, BNL) tbr their participation and assistance as conveners for various sessions of the symposium. My special thanks to Drs. William J. Marciano (BNL, Physics Department), David Sutter (U. S. Department Of Energy), Roy Blumberg (BNL, NSLS), and John Axe (Directors office) for helpful suggestions and discussions. In addition, my thanks to R. Femow, R. Greenberg, F. Devito and members of the Local Users Group (LUG) for their assistance with the Symposium mailing.
