More than two decades after the discovery of the first exoplanet with radial velocity (RV) measurements, large quantities of data exist from dedicated planet-hunting spectrographs. These spectra play an important role not only in the discovery and characterization of planets but also as a rich source of information about bright stars in the solar neighborhood. I will summarize recent efforts to gain insight into the planet formation process via extremely precise (0.01 dex) abundance measurements of solar twin stars with and without planets. I will also discuss approaches to the data analysis challenge of extracting maximally-precise RV measurements from these spectra in pursuit of Earth-like planets.
