ADC_Keywords: QSOs ; Polarization Keywords: quasars general - polarization - gravitational lensing Description: This Table contains linear polarization measurements (mainly in the V band) of 203 QSOs. First time measurements have been obtained for 184 objects. Among them 109 known radio emitters, 42 BAL and 1 gravitationally lensed QSO.
