  Holographic currents and their associated Ward identities are derived in the
framework of gravity/gauge duality. Holographic improvements of the
energy-momentum tensor and R-symmetry current which are consistent with the
Ward identities are displayed. The effects of specific string loop corrections
to the bulk action are included as four derivative effective lagrangian terms
and their contributions to the trace and R-symmetry anomalies of the boundary
theory are determined. As an example, the construction is applied to the N=2
conformal supergravity which is taken to be dual to a boundary SU(N)xSU(N), N=1
superconformal field theory.
