Work during the past year ranged from phenomenological studies of various quark systems to applications of quantum chromodynamics and lattice gauge theories. On the phenomenological side for mesons, studies of the charmonium and bottomonium families as well as the spectrum of states containing a single b-quark continued. As a result of some improved measurements, the topic of baryon magnetic moments was reconsidered. At the same time the properties of highly excited 3-quark systems were considered in view of the recent confirmation of resonances with spins up through 21/2. Quark configurations allowing for N colors were also studied, where N was varied. In the area of gauge field theories on a lattice, several interesting connections between gauge theories and interacting string models were found. Monte Carlo techniques were developed to study the problem of quark confinement, by means of a lattice version of QCD. Lastly, a new approach to the problem of quantizing gravity was started.
