K. C. Abstract The properties of optical continua and emission lines of 105 quasars, radio galaxies, and Seyfert galaxies are investigated by means of published multichannel spectrophotometry data. A strong continuity was indicated between broad-line AGNs and quasars in terms of similarities in the correlations between line luminosities and nonthermal luminosity; a correlation between H-beta and nonthermal luminosity suggests that the Balmer lines result from recombination after photoionization, and that the overall spectral index and the covering factor are similar.
