A method and apparatus for localized electronic data broadcast and reception of substantial volumes of readily updatable information includes providing a user with a hand-held, portable device (10) for selection, reception, storage, and retrieval of the information, providing at least one broadcasting source, and broadcasting information from the source so that, if the user is within range, the user may select, receive, store, and retrieve the information. The information is preferably transmitted in packets, and may include simultaneously or contemporaneously broadcasting differing sets of information. Programmability data may be transmitted with the information. The associated apparatus for selection, reception, storage, and retrieval of the substantial volumes of readily updatable locally broadcast electronic data includes a portable (10), hand-held body with a large, easily-read display screen and a plurality of keys positioned on the body to permit the user to select, receive, store and retrieve the information.
