In this paper we present new HI observations with high velocity resolution for 104 nearby narrow-line galaxies with half power line widths smaller than 50 km s^-1^ most of which are well approximated by a Gaussian. The FWHM line width of 30 of these integrated HI profiles is less than 25 km s^-1^. We present global parameters of these nearby galaxies and discuss the size dependence, the luminosity dependence, and the dependence of these parameters with the observed line width. Our sample essentially is a subsample of the Local Volume (I.e. galaxies within 10 Mpc) with declinations >= -30^deg^ and only a few galaxies at greater distances. It is described by the following median values of global physical parameters: total absolute blue magnitude M_B__t_ = -12.85; linear diameter A_0_ = 1.63 kpc (this corresponds to the de Vaucouleurs diameter D_25_); half power line width W_c_ = 29 km s^-1^; total HI mass M_HI_ = 2 x 10^7^ M_sun_; distance D = 5.1 Mpc; HI mass-to-luminosity ratio M_HI_/L_B_ = 0.9 M_sun_/L_sun_; total mass-to luminosity ratio M_t_/L_B_ = 2.9 M_sun_/L_sun_. Key words: galaxies: distances and redshifts - galaxies: dwarf - galaxies: general
