Principal Galaxies Catalogue (PGC)

A comprehensive catalogue of galaxies begun by Paturel and collaborators, providing a unique 'PGC' identifier, position, and basic parameters for tens of thousands of galaxies. It forms the backbone of the HyperLEDA database, and its PGC numbers are widely used as a standard cross-reference for galaxies lacking a common name.
