Abstract
The age of slow, methodical, star-by-star, single-slit spectroscopic observations of rare stars in the halo and thick disk of the Milky Way has come to an end. The use of new spectroscopic survey techniques which obtain large sky coverage to faint magnitudes will enable substantially better `return on investment' in the near future. We review the present state of surveys for low metallicity, field horizontal-branch, and sdM stars in the Galaxy, and describe new lines of attack which should open the way to a more than hundredfold increase in the numbers of interesting stars with available spectroscopic information.
