The absorption lines observed in quasar spectra have given us a detailed picture of the in-tergalactic medium and the metal abundance and kinematics of high redshift galaxies. In this review, we present an introduction to the field, starting with the techniques used for interpreting absorption line spectra. We then survey the observational… CONTINUE READING
