 to search for radio-quiet BL Lac candidates using intranight optical variability (INOV) as a probe. The present INOV observations cover a well-defined representative set of 00 `radio-quiet weak-emission-line quasars' (RQWLQs), selected from a newly published sample of 00 such sources, derived from the Sloan Digital Sky Survey (Data release 0). Intranight CCD monitoring of the 00 RQWLQs was carried out in 00 sessions lasting at least 0.0 h
