Spectrophotometric surveys were made of the galactic anticenter open clusters King 8 and Be 19 to obtain abundance data in support of galactic evolution studies. The data were taken at Kitt Peak with a 600 lines/mm grating centered at 4500 or 4700 A with 9.5 A resolution. The clusters are 3 kpc beyond the solar system going outward toward the rim. The presence of two early type (A5 or less) stars in King 8 was consistent with the stars' photometric positions in the color-magnitude diagram. Both clusters were slightly metal-poor, like the clusters NGC 2158 and 2420, which is in accordance with previous estimates of the galactic abundance gradient.
