Abstract:
    We present preliminary results form a long-term program of mapping the
    neutral absorption characteristics of the local interstellar medium,
    taking advantage of Hipparcos stellar distances. Equivalent width of
    the NaI D-line doublet at 5890Å are presented for the
    lines-of-sight towards some 143 new target stars lying within 300pc of
    the Sun.
