It has recently been proposed that a class of supersymmetrichigher-derivative interactions in N=2 supergravity may encapsulate an infinitenumber of finite size corrections to the microscopic entropy of certainsupersymmetric black holes. If this proposal is correct, it allows one to probethe string theory description of black-hole micro-states to far greateraccuracy than has been possible before. We test this proposal for ``small''black holes whose microscopic degeneracies can be computed exactly by countingthe corresponding perturbative BPS states. We also study the ``black holepartition sum'' using general properties of of BPS degeneracies. Thiscomplements and extends our earlier work in hep-th/0502157Comment: 103 pages, uses JHEP3.cl
