  We have analyzed optical spectra of 473 X-ray and 235 optically selected
AGNs, to study their emission line properties. We present results of an
analysis of the H-beta linewidths. We find that the linewidth distribution of
quasars is shifted towards higher velocities (<v>=4300 km s-1) compared to the
distribution of Sy 1s (<v>=3000 km s-1). There are no Narrow Line Quasars, i.e.
there are no AGNs with quasar luminosities and FWHM(H-beta) < 2000 km s-1.
NLSy1s comprise 20-30 per cent of the AGN population at faint absolute
magnitudes (MB>-22), irrespective of the selection method. In the RASS sample
we find Gamma [0.1-2.4 keV] < 3.3. The Gamma vs. FWHM(H-beta) distribution for
Sy 1 galaxies is consistent with previous work. For QSOs the spectral index
also flattens with increasing FWHM(H-beta), but they have larger linewidths
than Seyfert 1s.
