Scientific paper

The author presents evidence for field-galaxy evolution from deep CCD multicolor observations of a statistically complete sample of galaxies in 12 high-latitude fields. Galaxy counts fainter than 24 BJ mag exceed that expected in models in which most stars were formed at redshifts greater than 3. In this paper, the author mainly addresses the data, rather than models, and concentrates on the issues of systematic error and statistical reliability. The data cover the range 17 - 28 BJ mag and contain two-color data (BJ - R, R - I) on galaxies fainter than BJ = 21 mag. In the absence of detailed models of galaxy and star formation, some general conclusions are drawn from these data regarding the diffuse light from galaxies, the luminosity function at recent epochs, and the history of galaxy color and luminosity evolution.
