Abstract
Studies of radio-source astrophysics and cosmology are based on samples for which typically 10 to 100 redshifts have been measured. Such samples are grossly inadequate given the diversity of radio-source populations and range of luminosities present. Redshift-acquisition has been long and tortuous; there are ≤ 103 known for a totality of ∼ 105 radio sources catalogued. Until now the match of surveys to multi-object spectroscopy has been impractical, even deep pencil-beam surveys (e.g. Fomalont et al., 1991; Windhorst et al., 1993) yielding typically 10 to 15 objects brighter than B = 22 mag within fields of view 7 to 16 arcmin in diameter.
