Abstract
We describe the present status of our compilation of measured redshift s for both A- and S-clusters of galaxies from Abell, Corwin and Olowin (AGO). Over the past five years the number of ACO clusters with measu red redshifts increased from similar to 1000 to similar to 1650. Howev er, the fraction of clusters with at least 3 member redshifts remained at similar to 30%. A velocity dispersion is known for similar to 330 ACO clusters. The median dispersion is 760 km s(-1) and a histogram of their distribution is presented.
