Galaxies play an important role in the evolution of the intergalactic medium (IGM). A significant fraction of the star formation in the local universe, and perhaps the majority of star formation at high redshift, occurs in starburst galaxies. The high spatial and temporal density of supernovae in starburst galaxies fuels galactic-scale outflows of interstellar gas. These outflows have been observed in galaxies over a broad mass range but only during the brief starburst phase. I review the measured properties of galactic winds here to aid comparisons to the kinematics and metallicities of quasar absorption line system. If some absorption line systems were clearly identifiable with relic winds, then the frequency and extent of galactic winds could be derived directly from statistical analysis of random sight lines.
