 There are currently over 350 known extrasolar planets, the vast majority discovered through detection of periodic barycentric reflex motion of the planet's host star via high-precision Doppler radial velocity measurements. The Lick-Carnegie Extrasolar Planet Search Program is one such precision Doppler-based planet survey. It is currently monitoring over 1330 nearby F,G,K, and M stars for planets at 2-3 m/sec precision, and has contributed over 70% of the presently-known exoplanets. These extrasolar planetary systems display an unexpected diversity of orbital period, size, and eccentricity, and the emerging database is providing new insight into the origins and evolution of planetary systems. This talk will give a brief review of our program, reviewing details of the detection method, recent results, and future directions. The talk will also highlight the 2.4-meter Automated Planet Finder, nearing completion at Lick Observatory.
