  Doubly-holographic models, also known as Karch-Randall brane worlds, have
shown to be very useful for understanding recent developments around computing
entropies in semi-classical gravity coupled to conformal matter. Although there
cannot be a faithful bulk/brane dictionary, we show that there is a simple
dictionary which relates brane fields to subleading coefficients of a
near-brane expansion of bulk fields -- similar to the case of AdS/CFT. We use
this dictionary to find a general formula for the leading order contribution to
graviton masses in the $d$ dimensional Karch-Randall braneworld.
