We report on our research on the UV, optical line parameters and the infrared through UV to soft X-ray continuum parameters for a composite sample of narrow line and normal Seyfert 1 galaxies. The strong correlations among the line width of Hβ, optical line strength of Fe II and the soft X-ray slope are confirmed. We found no correlations between the UV line parameters, the equivalent widths of Lyα and CIV and their ratio on one hand and the optical line parameters on the other. The UV and X-ray luminosities strongly correlate with the line widths of Hβ and the Fe II/Hβ ratio. No significant correlation is found between the infrared-soft X-ray continuum slope αix and the line width of Hβ.
