  We report on the results of a comprehensive search for Cepheid variable stars
in the fields photometricallymonitored by the OGLE Galaxy Variability Survey.
We identify 742 Cepheids not included in the first release of the OGLE
Collection of Galactic Cepheids and reclassify several dozen previously
published variables. The upgraded collection comprises 1974 classical, 1625
type II, and 119 anomalous Cepheids located in the area of about 3000 square
degrees covering the disk and bulge of the Milky Way.
  We present the most interesting objects in our sample: an isolated group of
long-period doublemode classical Cepheids pulsating in the fundamental mode and
first overtone, the first known Galactic double-mode Cepheid with the second
and third overtone excited, double-mode type II Cepheids, candidates for
single-mode first-overtone BL Her stars, and Cepheids showing simultaneous
eclipsing variability. We also discuss type II and anomalous Cepheids that are
potential members of globular clusters.
