  We present absorption-line strengths on the Lick/IDS line-strength system of
381 galaxies and 38 globular clusters in the 4000--6400 \AA region. All
galaxies were observed at Lick Observatory between 1972 and 1984 with the
Cassegrain Image Dissector Scanner spectrograph, making this study one of the
largest homogeneous collections of galaxy spectral line data to date. We also
present a catalogue of nuclear velocity dispersions used to correct the
absorption-line strengths onto the stellar Lick/IDS system. Extensive
discussion of both random and systematic errors of the Lick/IDS system is
provided. Indices are seen to fall into three families: \alpha-element-like
indices (including CN, Mg, Na D, and TiO_2) that correlate positively with
velocity dispersion; Fe-like indices (including Ca, the G band, TiO_1, and all
Fe indices) that correlate only weakly with velocity dispersion and the \alpha
indices; and H\beta which anti-correlates with both velocity dispersion and the
\alpha indices. C_2 4668 seems to be intermediate between the \alpha and Fe
groups. These groupings probably represent different element abundance families
with different nucleosynthesis histories.
