Abstract. I summarize current knowledge of galaxy formation
with emphasis on the initial conditions
provided by the 
CDM
cosmology, integral constraints
from cosmological quantities, and the demographics of high-redshift
protogalaxies. Tables are provided summarizing the number density, star
formation rate and stellar mass per object, cosmic star formation rate and
stellar mass densities, clustering length and typical
dark matter halo masses for Lyman break galaxies, Lyman alpha
emitting galaxies, Distant red galaxies, Sub-millimeter galaxies,
and Damped Lyman 
absorption systems. I also discuss five key unsolved problems
in galaxy formation and prognosticate advances that the near
future will bring.
Keywords: galaxies:formation, galaxies:high-redshift
