We present parameter and abundance data for a sample of 298 nearby giants. The spectroscopic data for this work have a resolution of R ~ 60,000, S/N > 150, and spectral coverage from 475 to 685 nm. Overall trends in the Z > 10 abundances are dominate

We present lithium, carbon, and oxygen abundance data for a sample of nearby dwarfs—a total of 216 stars—including samples within 15 pc of the Sun, as well as a sample of local close giant planet (CGP) hosts (55 stars) and comparison stars. The s

We present an abundance analysis for stars within 15 pc of the Sun located north of -30° declination. We have limited our abundance sample to absolute magnitudes brighter than +7.5 and have eliminated several A stars in the local vicinity. Our final
