We present lists of the radio sources from the 408-MHz Molonglo Reference Catalogue which have projected separations less than 500kpc (0.33 R_Abell_) from rich southern clusters of galaxies in the new Abell, Corwin & Olowin catalogue. There are 107 such sources in the directions of 94 clusters for the new southern catalogue, of which we estimate about 27 sources are chance alignments, not associated with the cluster concerned. We also list 89 sources similarly 'coincident' with clusters in the supplementary southern catalogue, and 99 for the revised northern catalogue (to the northern declination limit of the Molonglo Reference Catalogue, +18.5^deg^). We find a stronger concentration of the radio sources to the cluster centre than in previous work. We attribute this to the effects of dominant galaxies at the cluster centres, as revealed by better positional accuracy than for previous large-scale radio surveys of clusters.
