We present a sample of 1777 bright (9<B<14) metal-poor candidates selectedfrom the Hamburg/ESO Survey (HES). Despite saturation effects present in thered portion of the HES objective-prism spectra, the data were recoverable andquantitative selection criteria could be applied to select the sample. Analysesof medium-resolution (~2 A) follow-up spectroscopy of the entire sample,obtained with several 2 to 4 m class telescopes, yielded 145 new metal-poorstars with metallicity [Fe/H]<-2.0, of which 79 have [Fe/H]<-2.5, and 17 have[Fe/H]<-3.0. We also obtained C/Fe estimates for all these stars. From this, wefind a frequency of C-enhanced ([C/Fe]>1.0) metal-poor ([Fe/H]<-2.0) giants of9% +- 2%, which is lower than previously reported. However, the frequencyraises to similar (>20%) and higher values with increasing distance from theGalactic plane. Although the numbers of stars at low metallicity are fallingrapidly at the lowest metallicities, there is evidence that the fraction ofcarbon-enhanced metal-poor stars is increasing rapidly as a function ofdeclining metallicity. For ~60 objects, high-resolution data have already beenobtained; one of these, HE 1327-2326, is the new record holder for the mostiron-deficient star known.Comment: 29 pages (emulateapj), accepted for publication in Ap
