  We present a new catalog of 1575 contact binary stars fainter than I=18 mag
identified in OGLE-I database in the selected directions toward the Galactic
bulge and the Galactic bar. For completeness we recall here also the objects
from the formerly published OGLE catalog of contact binaries brighter than I=18
mag.
  To ease the comparison and/or distinction between contact binaries with
sinusoidal light curves and pulsating stars we also give a catalog of 506
objects with nearly sinusoidal light curves which were classified or
re-classified as pulsating variable stars.
  Present catalog contains the most numerous, observationally homogeneous
sample of contact binaries. Given are the statistical properties of the sample
relating to the distributions of brightness, periods and amplitudes of the
contact binaries.
