ADC_Keywords: BL Lac objects ; Polarization

Description:
    This paper continues publications that report the results  of
    photoelectric polarization measurements of the blazar BL Lac.
    Earlier, we published observational data obtained over the period
    1969-1982 (Gagen-Torn et al., 1984AZh....61..925G). Here, we 
    discuss the observations over the period 1983-1991.
