Abstract We present the column density distribution of the LISM towards a sample of 15 fast rotators observed with IUE at high resolution. The targets are closer than 200 pc and most of them have lines of sight not previously investigated. Hydrogen column densities are inferred using zinc, known to be little depleted. The results are in general agreement with the broad picture of the LISM drawn by Paresce, with the possible exception of some cases which are discussed. For the few stars for which long wavelength images were available we attempt to derive the MgII/MgI ratio to obtain information on the temperature of the gas in the line of sight.
