Abstract

I discuss the prospects for using QSO absorption-lines to measure large-scale structure and peculiar motions at unprecedented redshifts; z=1-4. I review the existing data, which though very incomplete suggests that at redshifts around two, large scale structure was already well developed, but that peculiar motions were very low. With the advent of 2dF, it should be possible to track the evolution of large scale structure right through the epoch of galaxy and cluster formation.
