  In quantum teleportation, an unknown quantum state is transmitted from one
party to another using only local operations and classical communication, at
the cost of shared entanglement. Is it possible similarly, using an $N$ party
entangled state, to have the state retrievable by {\it any} of the $N-1$
possible receivers? If the receivers cooperate, and share a suitable state,
this can be done reliably. The $N$ party GHZ is one such state; I derive a
large class of such states, and show that they are in general not equivalent to
the GHZ. I also briefly discuss the problem where the parties do not cooperate,
and the relationship to multipartite entanglement quantification. I define a
new set of entanglement monotones, the entanglements of preparation.
