  The emission and absorption attributes of the UV-blue nuclear spectra of the
Narrow-Line Seyfert 1 (NLS1) galaxies are analyzed based on high quality
archival HST observations. Measurements from composite spectra as well as from
individual sources reveal differences from the more general AGN samples: NLS1s
have steeper (redder) UV-blue continua. Objects with UV line absorption show
redder spectra, suggesting that internal dust is important in modifying the
continuum shapes. A strong relationship is found between the slopes of the
power-laws that best fit the UV-blue continua and the luminosities: the more
luminous sources have bluer SEDs. This trend is possibly attributed to a
luminosity-dependent inner geometry of the obscuring (dusty) material.
