Number counts, colors, and angular correlations of field galaxies fainter than 20th mag are summarized. Resulting conclusions regarding the presence and nature of luminosity, spectral, and clustering evolution remain controversial. Preliminary analysis of two major spectroscopic surveys near completion suggests that by z ∼ 0.5, larger numbers of very-blue galaxies of moderate luminosities are found than today. These skewer-like surveys also provide new probes of galaxy clustering on scales previously unexplored (>200 Mpc) and over lookback times of several billion years.
