1) Variability Monitoring of NGC 3516: In NGC 3516 we established that the UV intrinsic absorption lines were the most variable ever seen in any Seyfert 1 galaxy. We have continued to observe NGC 3516, and are in the process of intergrating emission line and absorption line results in our models. 2) Lyman Edges in Polarized Light: I have investigated the spectral region around the Lyman edge in polarized light and have shown that the UV polarized light observations are inconsistent with simple accretion disk models. Simple plane parallel atmospheres with scattering dominated opacity are not present in AGN. 3) LINERS: Starbursts or AGN? Our investigations of LINER nuclei show that multi-wavelength observations are crucial to understanding the nature of these objects. We find in some cases that the line emission mechanism is similar to luminous AGN, but in some cases the UV continuum is a nuclear starburst rather than a miniature AGN. Our multiwavelength observations firmly establish the heterogeneous nature of the LINER class.
