Dual AGNs have long been suspected to represent an important phase in galaxy mergers where both central supermassive black holes involved are actively accreting and contributing to some of the most significant black hole growth. But years of searches have turned up far fewer dual AGNs than expected. In this talk, I will give a brief overview of the state of this field and its limitations, and discuss several observational campaigns with which I have been involved to hunt for dual AGNs at different epochs. The emerging conventional wisdom is that a multi-pronged, multi-wavelength approach is no longer a luxury, but instead a necessity to convincingly identify these rare systems.
