The search for electric dipole moments (EDMs) constitutes a powerful, and yet relatively inexpensive, probe of new physics above the electroweak scale, in the context of flavour-blind CP violation. I'll review some recent developments, and some inherent difficulties, in computing the dependence of observable EDMs, e.g. of the neutron, Tl and Hg, on operators in the CP-odd effective Lagrangian at 1 GeV. I'll also discuss the generation of these sources within the MSSM, emphasizing the importance of certain four-fermion operators at large tan(beta), and the ensuing constraints on CP-odd phases.
