A brief summary is given of the plate materials and results obtained at Yale since the advent of photographic astrometry. The distributions of plates not yet measured or reduced are indicated and possible supplementary programmes for their effective utilization are discussed. Interest centres chiefly in the following areas:
(1) The unmeasured parallax plates.
(2) Reduction of the −60° to −70° zone catalogue.
(3) The El Leoncito programmes for the determination of both positions and proper motions relative to faint galaxies.
(4) The feasibility of a search for intrinsically faint nearby stars with the Yale 40-in. at Cerro Tololo and the 20-in. double astrograph at El Leoncito.
