Abstract
First, a historical overview is presented concerning the use of QCD sum rules to learn about the rho-meson properties at finite nuclear densities. Second, it is shown that the combination of the sum rule technique with the large-N-c expansion provides new insight. Especially it is possible to determine from the in-medium sum rules a vacumn(!) quantity which is an important ingredient for hadronic in-medium calculations of the rho-meson spectral function. This quantity is the coupling strength of the rho-nucleon system to the baryonic resonance N* (1520).
