Abstract
We present a catalog of interstellar polarization measurements for the North Galactic Pole area ( $b > 70\degr$). 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.


Key words: polarization -- dust, extinction -- solar neighbourhood
