  We present results from an observing campaign to identify low-metallicity
stars in the Best & Brightest Survey. From medium-resolution (R ~ 1, 200 - 2,
000) spectroscopy of 857 candidates, we estimate the stellar atmospheric
parameters (Teff, log g, and [Fe/H]), as well as carbon and alpha-element
abundances. We find that 69% of the observed stars have [Fe/H] <= -1.0, 39%
have [Fe/H] <= -2.0, and 2% have [Fe/H] <= -3.0. There are also 133
carbon-enhanced metal-poor (CEMP) stars in this sample, with 97 CEMP Group I
and 36 CEMP Group II stars identified in the A(C) versus [Fe/H] diagram. A
subset of the confirmed low-metallicity stars were followed-up with
high-resolution spectroscopy, as part of the R-process Alliance, with the goal
of identifying new highly and moderately r-process-enhanced stars. Comparison
between the stellar atmospheric parameters estimated in this work and from
high-resolution spectroscopy exhibit good agreement, confirming our expectation
that medium-resolution observing campaigns are an effective way of selecting
interesting stars for further, more targeted, efforts.
