Description:
    We  present the  Catalog of  Periodic Variable  Stars in  the Galactic
    Bulge.  The Catalog is based on observations collected during the OGLE
    (Optical Graviational Lensing Experiment) microlensing search:
    (1)   213  periodic  variable  stars   brighter  than  Imag=18mag:  31
    pulsating,  116 eclipsing and 66 miscellaneous type variables from the
    Baade's Window BWC field are presented.
    (2) 800  variable stars found in four  Baade's Window fields BW1, BW2,
    BW3  and BW4 are presented. Among them 71 are classified as pulsating,
    465 as eclipsing and 264 as miscellaneous type.
    (3)  644   variable  stars:  64  pulsating,   352  eclipsing  and  228
    miscellaneous  type were detected  in four Baade's  Window fields BW5,
    BW6, BW7 and  BW8.  Analysis  of  periodic  variable  stars  found  in
    overlapping regions  of the  Baade's Window  fields yields  an average
    completeness  of the Catalog equal to  about 80% of periodic variables
    objects registered in the OGLE databases and about 65% of all periodic
    variable stars in the observed region of the sky.
    (4)  631   variable  stars:  59  pulsating,   348  eclipsing  and  224
    miscellaneous type  were detected in third  Baade's Window fields BW9,
    BW10, and BW11.
    (5)   574  variables  stars:  44  pulsating,  369  eclipsing  and  161
    miscellaneous  type were detected in four fields located symmetrically
    in the  galactic latitude  around the  Galactic center:  MM5-A, MM5-B,
    MM7-A and MM7-B.
