Resumen:
The collection of photographic plates at the La Plata Observatory contains a large number of plates taken with the Astrographic Telescope of aperture 343 mm and focal lenght 3.42 m. The data from direct-photographic observations have been organized as a computer readable-catalogue of plates since 1948. We have available 2030 plates of asteroids and 156 plates of comets, with a field of 2deg X 2deg on plates of 16cm x 16cm. The coordinate distribution of plates centres by equatorial coordinates largely covers most part of the southern hemisphere. The limit of declination is -70deg. The data from the observation catalogue have been analysed in order to derive some overall characteristics of the plate archive.
