Abstract

Recent results have shown that emission-line variability studies are potentially valuable for determining the size and structure of the BLR. However, this potential has not been fully realized, primarily on account of insufficient data. It is clear that size determinations will require better temporal resolution since the BLR is apparently smaller than estimated earlier. On the other hand, experience with NGC 5548 suggests that a very lng baseline of observations will be required to investigate the kinematic structure of the region. Considerable emphasis needs to be placed on long-term spectroscopic monitoring programs that provide good temporal resolution.
