Galaxy halos - where the dynamical timescale is comparable to the age of the Universe - offer a unique opportunity to trace the fossil records of those processes which led to the formation of galaxies the way we observe them today.

Reliable observations of stellar kinematics and stellar populations - to two effective radii and beyond - will be presented. We shall discuss how well the cosmological models compare with the observed kinematics and stellar populations properties. The goal is to identify those observational strategies and model developments which will lead to a deeper understanding of galaxy evolution.
