Observations of AGB and Super AGB stars.

Multi-wavelength and multi-epoch surveys of Asymptotic Giant Branch (AGB) stars in galaxies have provided critical observational constraints in heretofore unexplored parameter space. I will review the current inventory of AGB observations in nearby galaxies, from metal-poor dwarfs to the metal-rich, star-forming spiral, M31. In particular, I will discuss efforts to identify and characterize the massive hot bottom burning and super-AGB stars in the Magellanic Clouds, and the lessons we can apply to more distant galaxies where data is less abundant.
