We present a compilation of properties of the 105,783 quasars in the Sloan Digital Sky Survey Data Release 7 (DR7) quasar catalog. In this product, we compile continuum and emission line measurements around the H alpha, H beta, Mg II, and C iv regions, as well as other quantities such as radio properties, and flags indicating broad absorption line quasars, disk emitters, etc. We also compile virial black hole mass estimates based on various calibrations. For the fiducial virial mass estimates we use the Vestergaard & Peterson (VP06) calibrations for H beta and C IV, and our own calibration for Mg II which matches the VP06 H beta masses on average. We describe the construction of this catalog and discuss its limitations. The catalog and its future updates will be made publicly available online.
