We present the data from 3 years of monitoring the optical polarization and apparent brightness of 37 X-ray selected BL Lacertae objects. The monitored objects include a complete sample drawn from the Einstein Extended Medium Sensitivity Survey (EMSS). We confirm the BL Lac identifications for 15 of these 22 objects. We include descriptions of the objects and samples in our monitoring program and of the existing complete samples of BL Lac objects, highly polarized quasars, optically violent variable quasars, and blazars. The data are analyzed and implications discussed in Jannuzi, Smith, and Elston (Paper II).
