The Commission or its authorized representative may require the Postal Service to provide any information, documents, and things in its possession or control, or any information, documents, and things that it can obtain through reasonable effort and expense, that are likely to materially assist the Commission in its conduct of proceedings, in its preparation of reports, or in performance of its functions under title 39 of the U.S. Code. Information, documents, and things the Postal Service may be required to provide, include, but are not limited to, paper hard copy and electronically stored data and materials--including writings, notes, e-mails, drawings, graphs, charts, photographs, sound recordings, images, and other data or data compilations--stored in any medium from which information can be obtained either directly or, if necessary, after translation into a reasonably usable form; or any tangible things.
