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.
