Abstract:
    We present B, R, and Hα images for a total of 114 nearby
    galaxies (vhelio<4000km/s) that, with exception of nine objects, are
    classified as blue compact dwarfs (BCDs). BR integrated magnitudes,
    Hα fluxes and Hα equivalent widths for all the objects in
    the sample are presented.
