I will explain how “group completion” techniques lead to a description of the cohomology of braid groups(=spaces of configurations in the plane) and mapping class groups(=moduli spaces of Riemann surfaces). I hope to explain the method completely for braid groups, and indicate what one needs to worry about for mapping class groups. I will then survey explicit calculational information which can be obtained from this method (and others).
