Abstract
We present a catalogue of 233 BL Lacertae objects compiled through an extensive
bibliographic search updated to mid-1995. A large fraction of the sources
listed in the catalogue belongs to well-defined samples and can be used for
statistical purposes. A smaller fraction consists of miscellaneous (but
confirmed) BL Lacs and of objects classified as BL Lac candidates. We discuss
the selection criteria of the different samples, report the discovery of two
previously unnoticed BL Lacs in the Palomar--Green survey, and comment on the
possible association of some of the still unidentified high galactic latitude
gamma-ray (EGRET) sources with BL Lacs. Some statistical properties of the
catalogue are also briefly discussed.
