CCD and HI observations of LSB dwarf galaxies in the general field

CCD B and V observations of 16 low-surface-brightness galaxies and HI data for a subsample of 4 of them are presented. Both paired and isolated dwarf galaxies are observed to study possible environmental effects on their characteristics. Most of the observed galaxies are true dwarfs with -8.0 greater than or equal to M(B) greater than or equal to -16.0, blue colours (0.16 less than or equal to B - V less than or equal to 0.76) and low central surface brightnesses 22.2 less than or equal to mu(B) less than or equal to 24.0 mag arcsec(-2). Most of them show exponential light profiles with a central light depression. About half of them have bright generally blue knots or peculiar loops.
