We present simultaneous UBV linear polarization measurements for 361 A- and F-type stars with accurate colour excess and distance determination. These stars are distributed in 35 Kapteyn's Selected Areas, covering the third and fourth quadrants of the galactic plane (|b|≤30°). The obtained polarization and the known colour excess are compared. An analysis of the polarization distribution as a function of the stellar distance is also performed.
