Abstract: Damped Ly alpha systems seen in spectra of background quasars are generally thought to represent high redshift counterparts of present-day galaxies. We summarize observations of heavy element abundances in damped Ly alpha systems. The results of a systematic search for CO and {Cii}^* absorption in 17 damped Ly alpha systems are also presented using observations obtained with the 10m Keck telescopes. The latter provides a useful constraint on the expected strength of [{Cii}] 158 micron emission from damped Ly alpha galaxies. It is hoped that these results will be useful for planning future radio to millimeter wave observations of high redshift galaxies using next generation instruments which are now being built.
