Query: Dust Absorption and Emission in Galaxies at High and Low Redshifts   This article reviews three related topics: the extragalactic background l
ight and its sources, evolution models for the dust absorption and emission in
galaxies, and empirical constraints on these transfer pr ocesses in nearby
starburst galaxies. It is intended that the material presented here will serve
