Imaging and spectroscopic observations designed to detect intervening galaxies responsible for low redshift Mg II absorption line systems in quasar spectra are presented. Data are presented for 12 absorption systems detected in 10 quasar sightlines. A comparison is made between the observed distribution of the absorber-quasar projected linear separations and the computed distribution of impact parameters in an attempt to constrain the size and shape of the absorbing regions.
