In this paper we present the second and final part of a large and photometrically homogeneous CCD color-magnitude diagram ( CMD ) data base , comprising 52 nearby Galactic globular clusters ( GGC ) imaged in the V and I bands .

The catalog has been collected using only two telescopes ( one for each hemisphere ) .
The observed clusters represent 75 \% of the known Galactic globulars with ( m - M ) _ { V } \leq 16.15 mag , cover most of the globular cluster metallicity range ( -2.2 \leq { [ Fe / H ] } \leq - 0.4 ) , and span Galactocentric distances from \sim 1.2 to \sim 18.5 kpc .

In particular , here we present the CMDs for the 13 GGCs observed in the Northern hemisphere .
The remaining 39 Southern hemisphere clusters of the catalog have been presented in a companion paper ( Rosenberg et al . [ 2000 ] ) .
We present the first CCD color magnitude diagram for NGC 6779 ( M56 ) .

All the CMDs extend from at least \sim 2 magnitudes below the turn-off ( i.e . V _ { lim } \geq 22 ) to the tip of the red giant branch .
The calibration has been done using a large number of standard stars , and the absolute calibration is reliable to a \sim 0.02 mag level in both filters .

This catalog , because of its homogeneity , is expected to represent a useful data base for the measurement of the main absolute and relative parameters characterizing the CMD of GGCs .
