Popular name for the Catalogue of Galaxies and of Clusters of Galaxies (also referred to simply as "The Red Book") published in six volumes in 1961-68 by Fritz Zwicky and his colleagues. It contains 31,350 galaxies and 9,700 clusters recorded on plates of the Palomar Observatory Sky Survey and introduces a system of classifying clusters as compact, medium compact, or open that is still used. Compact galaxies identified in the Zwicky Catalogue are often known as Zwicky galaxies.
