I shall discuss studies that can be carried out withthe Space Telescope (ST) of absorption-line systems which may be expected to occur in the spectra of distant objects.

Absorption-line systems with redshifts very different from the emission-line redshift have so far been observed only in the spectra of quasars and BL LAC objects. However, the fact that quasars exhibit rich absorption spectra and galaxies have not yet been observed to do so may be explained by two selection effects. Galaxies are by definition fainter than quasars and most of the strong absorption lines occur in the far ultraviolet. Thus galaxies at the redshifts sufficient to shift the absorption systems into the visible region are too faint to be studied at the high resolution necessary to detect narrow absorption lines.
