Groundbased surveys for intermediate-redshift QSOs from the populous faint end of the quasar luminosity function often suffer from significant morphological contamination by compact galaxies. To address this problem, we have conducted an archival multicolor and morphological HST survey for faint QSOs to B<24.5, z<2.1 that takes advantage of the 0.1” spatial resolution of WFPC2 images. QSO candidates are selected based on UV-excess and either stellar or unresolved-nucleus plus resolved host galaxy morphology. Our survey includes 31 high-galactic latitude pure parallel fields that have been imaged deeply with WFPC2 in U, R, and I covering 0.04 deg2 of the sky. We identify 19 new high-likelihood QSO candidates and derive a cumulative surface density of 511 deg-2 to B<24.5 and z<2.1, confirming our results from an earlier survey we conducted in the Groth-Westphal Strip. Our results are also in reasonable agreement with those from other faint quasar surveys that are based on very different candidate selection approaches.
