We describe the first results of the observational programme of photom
etry and spectroscopy of the ESO Nearby Abell Cluster Survey (ENACS).
The final data base contains a. total of 5634 galaxies in the directio
n of 107 clusters with richness class R greater than or equal to 1 and
redshift z less than or equal to 0.1. Applying a velocity gap of 1000
km/s, we identify galaxy systems in the 107 ''pencil-beam'' surveys.
The large majority of the clusters observed appear to be real, physica
l systems.
