Abstract:
Direct imaging and spectroscopic data are reported for the complete
sample of 34 BL Lac objects selected from the 1Jy source catalogue
(see Cat. VIII/5). A short description of each individual object is
given along with a general discussion of the features observed in the
optical spectra, the optical morphologies, and the environments of the
BL Lac objects.
