The Federal Register is the official daily publication for rules, proposed rules, and notices of Federal agencies and organizations, as well as executive orders and other presidential documents. Published by the Office of the Federal Register (OFR), National Archives and Records Administration (NARA), it is updated daily and is available Monday through Friday, except Federal holidays. GPO's Government Information System (govinfo) contains Federal Register issues from 1936 to the present. The current XML data set is not yet an official format of the Federal Register. The XML-structured files are derived from SGML-tagged data and printing codes, which may produce anomalies in display. In addition, the XML data does not yet include image files. Users who require a higher level of assurance may wish to consult the official version of the Federal Register on govinfo.gov or federalregister.gov. The govinfo data set includes digitally signed Federal Register PDF files, which may be relied upon as evidence in a court of law.

The Records Control Schedules (RCS) repository provides access to scanned versions of records schedules, or Standard Form 115, Request for Records Disposition Authority, that have been developed by Federal agencies and approved by the Archivist of the United States.
