We will survey a range of topics in Hopf-Galois module theory. In particular, we will look at tools for studying integral Hopf-Galois module structure when the associated order is not a Hopf order, Hopf-Galois module structure for “opposite” Hopf-Galois structures, the case of tamely ramified extensions, and extensions of number fields
