Scientific paper

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.
