Abstract:
    We present a catalog of interstellar polarization measurements for the
    North Galactic Pole area (b>70°). Our list contains 336 stars of
    spectral classes from A to K for which the linear polarization has
    been measured by us and other researchers. The data are useful for
    investigation of the distribution of dust, to estimate the amount of
    interstellar extinction and to map Galactic magnetic field at high
    galactic latitudes. We discuss also the data selection, sampling and
    completeness of the catalog.
