In terms of activity in the nucleus, LINER-like galaxies form an important link between giant HII region galaxies and low-luminosity Seyferts. Despite their large numbers and evolutionary significance, we do not know whether these galaxies form a homogeneous class of objects; nor do we know how the distribution, and kinematics of the emission-line gas are affected by the properties of the central engine, if present.
To address these issues we have constructed a large sample of nearby galaxies with LINER-like characteristics. While studies of individual "LINERS" have led to a certain understanding of the phenomemon, these studies have not provided a global framework, thus requiring a statistically large sample.
Here we present the kinematic and spectroscopic results of a sub-sample of galaxies obtained at the Michigan-Dartmouth-M.I.T. Observatory. The information gleaned from spectroscopic data, when combined with data at other wavelengths, will enable a thorough investigation into the nature of low luminosity nuclear activity.
