A comparison between three types of intervening absorption line systems: the Lyα forest, the Lyα damped systems and the narrow metal line systems has been done for the observational properties including the frequency of the systems, the equivalent width distribution, the two point correlation function, the metal abundances, and the dN/dz vs. z behavior.
