Redshift controversy

A comprehesive review (Reboul, 1981) of 772 reports, dealing with anomalous redshifts published before 1980, provides an interesting insight into an ongoing redshift controversy. A total of 216 of these were found to be explained adequately by standard cosmology while 33 more were explained with bias and in 8 cases there were not sufficient data for useful comment.
