We will take PC snapshots of a large, complete sample of early-type galaxies {130 galaxies in total}, with the object of examining the nuclear morphology. The survey will complement Illingworth's snapshot study of later Hubble types and provide a data base for the investigation of correlations of properties such as dust, metallicity, and colors with nuclear structure. Earlier work with the HST on the nuclear morphology of early-type galaxies has revealed that there is a clear dichotomy amongst these objects. They either have a shallow {but non-zero} surface brightness cusp, or their surface brightness continues to rise as a power-law all the way into the center, without the sign of a clear break-radius. The former we will denote as core-galaxies, while the latter will be called power-law galaxies. A number of the power-law galaxies were found to harbor small, bright, stellar disks in their nuclei. This large survey of early type galaxies will allow the investigation of the frequency of these nuclear disks. We will also investigate the relation between central cusp steepness and other parameters such as total magnitude, nuclear morphology and other galactic phenomena.
