Radio sources from the B2 catalogue have been identified with galaxies in the 'Catalogue of Galaxies and of Clusters of Galaxies' (Zwicky and Herzog 1963, 1966; Zwicky and Kowal 1968). 54 ellipticals, 3 peculiar galaxies and 10 spiral galaxies were found. All these objects have been observed at 1415 MHz at Nancay, 42 have been observed at Westerbork and a few at Nancay at 5000 MHz. These observations allow the determination of the radio spectrum and a study of the radio structure. Spectroscopic observations have also been made at McDonald Observatory and Kitt Peak National Observatory providing redshifts for 41 galaxies and as a result the redshifts are known for all the galaxies except 3 spirals. The results of the radio and optical observations are given in the present paper; the interpretation of the data is discussed elsewhere.
