The catalog contains a list of redshifts for Zwicky's Near Clusters. All of the 503 Zwicky Near Clusters as given in the Uppsala General Catalogue of Galaxies (UGC) are listed and radial velocity information for those that have at least one galaxy with published redshift positioned within the contours given in the Zwicky catalog is provided. Redshifts of galaxies belonging to clusters is obtained from the catalog of Radial Velocities of Galaxies. The catalog includes UGC cluster numbers, Zwicky field numbers, contour numbers, positions, heliocentric cluster radial velocities, and notes.
