A document administration system includes document storing apparatuses and a server connected via a network. Each of the document storing apparatuses includes plural boxes for storing information. The server includes an output request receiving portion for receiving an output request on a document stored in one of the document storing apparatuses; and an output destination selecting portion for selecting one of the document storing apparatuses for outputting the document corresponding to the output request. A discriminating portion of the server discriminates whether the selected document storing apparatuses coincides with the document storing apparatuses in which the document is stored. If so, a controller of the server makes the selected document storing apparatus output the document. If not, the controller obtains the document from the document storing apparatus in which the document is stored and transmits the obtained document to the selected document storing apparatuses to output the document.
