1. A computer-implemented method comprising: under control of one or more computer systems configured with executable instructions, receiving, at a server, a request from a first user to store a media item for later access by an electronic book reader device associated with a second user, wherein the request from the first user does not include information identifying the second user or the electronic book reader device associated with the second user as an intended recipient of the media item; in response to receiving the request at the server, associating a pass phrase with the request to store the media item; sending the pass phrase from the server to a device of the first user or to another device associated with the first user; after sending the pass phrase, receiving, at the server, the media item from the device of the first user; after receiving the media item at the server, storing the media item in association with the pass phrase, the pass phrase being usable for the later access of the media item by the electronic book reader device associated with the second user; receiving, at the server, the pass phrase from the electronic book reader device associated with the second user; and sending the media item from the server to the electronic book reader device associated with the second user at least partly in response to the receiving of the pass phrase at the server.
