  The advent of 8m-class telescopes has made galaxies at 1 < z < 4 relatively
easy to detect and study. This is a brief and incomplete review of some of the
recent results to emerge from surveys at these redshifts. After describing
different strategies for finding galaxies at z >~ 1, and the differences (and
similarities) in the resulting galaxy samples, I summarize what is known about
the spatial clustering of star-forming galaxies at z >~ 1. Optically selected
galaxies are the main focus of this review, but in the final section I discuss
the connection between optical and sub-mm samples, and argue that the majority
of the 850 micron background may have been produced by known optically selected
populations at high redshift. Among the new results presented are the
dust-corrected luminosity function of Lyman-break galaxies at z~3, the
estimated contribution to the 850 micron background from optically selected
galaxies at 1<z<5, revised estimates of the spatial clustering strength of
Lyman-break galaxies at z~3, and an estimate of the clustering strength of
star-forming galaxies at z~1 derived from a new spectroscopic sample of ~800
galaxies with <z> = 1.0, sigma_z = 0.10.
