This page lists some of the more interesting galaxy clusters.
Defining the limits of galaxy clusters is imprecise as many clusters are still forming. In particular, clusters close to the Milky Way tend to be classified as galaxy clusters even when they are much smaller than more distant clusters.

Abell galaxy clusters
An almost complete catalogue of approximately 4000 clusters with at least 30 members to a redshift of z = 0.2. Originally compiled by George Abell in 1958 using the plates of POSS, and extended to the southern hemisphere by Abell, Corwin and Olowin in 1987.
