20 SUMMARY Variability-based AGN selection finds AGN populations missed by other optical selection techniques. From the variability analysis, there is evidence that the region emitting in the XRs is more compact than the region emitting in the optical. BL objects show stronger variability than NL sources. Most of the NL AGNs are located in a region of the A-γ space similar to the one occupied by galaxies, however some of them show a variability behavior closer to BL objects. This sources can be true-type NL AGNs, transitional AGNs, or exceptions to the unified model. The amplitude of the variability A determined by the Structure Function shows a positive correlation with redshift, which implies a positive correlation between frequency and amplitude of the variability. However, the structure of the variability, represented by γ, is independent of the frequency of the emission.
