Abstract This paper contains a compilation of basic information on QSO absorption systems. A total of 724 QSOs are listed in three tables. Table 1 contains 353 QSOs that have absorption-line systems with measured redshifts. The numerous Lyα forest systems based only on narrow hydrogen lines are excluded from Table 1. Absorption systems with multiple components are listed only once if all of the components fall within a span of 500 km s^-1^. A total of 862 systems with narrow metal lines which we consider to be reliably identified are listed in Table 1. Table 1 contains an additional 260 systems consisting of less certain systems, damped Lyα systems, and Lyman limit systems that have no detected narrow metal lines. In Table 2 we list 146 broad absorption line QSOs. Fifteen of these have narrow absorption line systems identified, and thus they also appear in Table 1. In Table 3 we give an inhomogeneous list of 240 QSOs in which absorption systems have been seen but not measured. Also shown are histograms of emission redshift, absorption redshift, and (1 + Z_em_)/( 1 + Z_abs_) for the reliably identified narrow metal line systems. Several selection effects are apparent in this collection of data.
