With the aim to sample well the Local Interstellar Medium (LISM),we propose to use A stars as targets. The Mg II UV lines seems to be the best interstellar absorption candidates. Several hundreths of A stars can be reached within 100 pc. First preliminary results (20 lines of sight) are presented, based on previous Copernicus and actual IUE observations.
