We present results of surveys for high redshift field galaxies selected by their having produced detectable absorption in the spectra of background QSOs. Such surveys, in essence selected by gas cross-section rather than by flux density, are almost completely independent of the conventional magnitude--limited redshift survey, and allow one to follow objects of normal luminosity well beyond z∼ 1, the redshift at which many of the standard techniques break down. We summarize the principal results for our completed survey at z ≤ 1, and give the preliminary results of a second survey designed to extend the sample to z=1.6. A general conclusion is that normal field galaxies exhibit strikingly little evolution in their space density, luminosity, and optical/IR colors to redshifts as high as z∼ 1.5. We discuss both the techniques involved and the implications of the results.
