was to integrate the Baer invariants into the homological algebra that was developing at the time. In this paper we are interested in the exact sequences, like the 5-term exact sequence of group homology that is usually proved by appealing to the spectral sequences of Lyndon and of Hochschild and Serre. It turns out that the Baer functors fall naturally,
