repository (n.)

late 15c. (Caxton), "vessel, etc., for storage," from French repositoire or directly from Late Latin repositorium "store," in classical Latin, "a stand on which food is placed," from noun use of repositus, past participle of reponere "put away, store" (see repose (v.2)).

The figurative sense of "place where anything immaterial is thought of as stored" is recorded from 1640s; commercial sense of "place where things are kept for sale" is by 1759.
