     ABSTRACT.  Photoelectric photometry in the BV passbands is presented
     for 33 nearby RR Lyrae stars.  CCD frames are used to recalibrate the
     photographic photometry of an additional 7 RR Lyraes to the Johnson B
     band. Light curves are presented for all 40 stars, along with derived
     light curve parameters. For one subset of stars, reddenings and
     distances are computed from the observed colors at minimum light,
     periods, mean magnitudes, and spectroscopic metal abundances taken
     from the literature. For a second subset of stars, metal abundances,
     distances, and reddenings are determined via Fourier decomposition of
     the light curves. The results of the two methods are compared.
