The evolution of galaxies is greatly influenced by their interactions. The Spitzer Interacting Galaxy Survey sample was designed to probe a range of interaction parameters using infrared data complemented by a range of other observations. It is comprised of the Keel-Kennicutt (Keel et al. 1985) complete sample of interacting galaxies chosen on the basis of association likelihood. This selection criterion avoids the biases found in those chosen on the basis of morphology, infrared brightness, or optical line diagnostics. The resulting sample contains 111 galaxies in 50 systems, located with cz < 4000 km/s. We present a multiwavelength atlas of these data, which has complete Spitzer coverage and almost complete GALEX coverage. This atlas will be used to investigate the variation of star formation and AGN activity along the interaction sequence and the physical processes involved. Trends observed in this sample will also compared to those predicted by numerical simulations.
