From new high resolution spectra of metal-poor giants we use equivalent widths of [O I], Sc II, and Fe II lines to derive new values of [O/Sc] and [O/Fe]. These results are generally consistent with previous determinations of oxygen abundances from [O I] lines, but the star-to-star scatter is greatly reduced.
