Several results from extensive imaging surveys of fields around quasars are summarized. These include the frequency of finding close companions to low-redshift radio-quiet quasars, the quasar-galaxy covariance amplitudes of radio-loud quasars from z=0.15 to z=0.65, and the preliminary analysis of three-colour photometry from two clusters of galaxies associated with quasars.
Quasars at redshifts < 1.0 provide excellent markers for discovering galaxies and galaxy clusters at moderately high redshifts. A comprehensive program of imaging and spectroscopic surveys of galaxies in quasar fields has been carried out over the past few years by myself and collaborators. In this paper, recent results are summarized and some new results are presented. Unless specified otherwise, Ho=50 km sec-1 and qo=0 are used throughout this paper.
