The presence of quasars at very early epochs, and of supermassive black holes in most "quiescent" galaxies, shows that AGN are (pardon the pun) central to galactic formation. In addition, upon closer look, many normal galaxies reveal the presence of low-luminosity AGN, which may be related to nuclear starburst activity and therefore the star formation history of the galaxy as well. Thus, the once-considered esoteric AGN are now known to be ubiquitous and important to the formation of large and small-scale structure. But how should we find them? Especially at lower luminosities, the AGN phenomena can be hidden or confused with other phenomena at various wavelengths. While selection effects have always been a problem, this issue is becoming even more important as we enter into a more survey-driven era of astronomy, where large sample sizes prohibit the close study of individual objects. I will present some of my recent work on the search for AGN in the new large surveys as well as on the study of individual objects in detail. The goal is to use multiwavelength studies of AGN to better understand the phenomena, and then use this information to derive large samples based upon physically meaningful criteria.
