A new type of catalogue of extragalactic objects is nearing completion in our department. the catalogue is on magnetic tape and is a compilation of data for galaxies and cluster of galaxies, together with references, and for counts of galaxies. At present this Metacatalogue contains about 3 × 105 entries - Abell and Zwicky clusters, Zwicky galaxies, Lick counts, Jagellonian counts and some others. the first two files of the catalogue can be obtained on request from the Centre de Données Stellaire at Strasbourg.
