We present chromospheric CaII activity measurements, rotation periods andages for ~1200 F-, G-, K-, and M- type main-sequence stars from ~18,000archival spectra taken at Keck and Lick Observatories as a part of theCalifornia and Carnegie Planet Search Project. We have calibrated ourchromospheric S values against the Mount Wilson chromospheric activity data.  From these measurements we have calculated median activity levels and derivedR'HK, stellar ages, and rotation periods for 1228 stars, ~1000 of which have nopreviously published S values. We also present precise time series of activitymeasurements for these stars.
