We report accurate redshifts of 110 active galaxies (mostly radio-loud objects at z < 0.4) observed in the course of a survey to find broad, double-peaked emission lines. These redshifts are measured from the narrow emission lines of these objects and are accurate to at least one part in 10 4. For each object we determine a redshift from high- and low-ionization lines separately, as well as an average redshift from all the available lines. We find that in about 15% of cases, the low-ionization lines yield a slightly higher redshift than the high-ionization lines; the average redshift difference amounts to a velocity difference of approximately 80 km s -1. In addition to the redshift measurements we also report revised redshifts for two objects as well as new classifications for three narrow-line objects.
