A key property of holographic dualities is that observables of the bulk theory are determined by their boundary values. In dualities containing gravity, this property is further refined: bulk observables are determined by their boundary values on a single time slice. This more refined version is known as "holography of information." In this talk, I will describe how holography of information arises from two ingredients common to gravitational theories: the gravitational Gauss law and quantum entanglement. I will then describe a simple model in which holography of information can be seen in the context of asymptotically AdS spacetimes which contain "causal shadows," i.e., regions of bulk spacetime which have no causal contact with boundary.
