Tutorials, History, and Statistics

The Federal Register publication system was established on July 26, 1935 as an official legal information service of the United States government.  It functions under the authority of the Administrative Committee of the Federal Register (ACFR), and operates through a statutory partnership of the National Archives’ Office of the Federal Register (OFR) and the U.S. Government Printing Office (GPO).  The ACFR delegates its day-to-day authority to the Director of the OFR. The OFR administers its programs under the Federal Register Act (44 U.S.C. Ch. 15), the GPO Electronic Information Access Enhancement Act (44 U.S.C. 4101), the Freedom of Information Act (5 U.S.C. 551 et seq.), and other public information laws of the United States.

The daily Federal Register on GPO’s Federal Digital System (FDsys) 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. It is updated daily, usually by 6 a.m., and is published Monday through Friday, except Federal holidays.   The website contains an unofficial HTML version of the Federal Register known as Federal Register 2.0 (FR2), which is presented in a unique web journal format. Each HTML rendering on FR2 includes a direct link to the official PDF rendering on FDsys. Both FDsys and FR2 contain Federal Register material from 1994 to the present. For more information on FR2, see “About Us” and “User Information.”

Analysis of  Federal Register Documents Received in 2013, PKI vs Non-PKI

The Office of the Federal Register is equipped to accept digital submission of Federal Register documents using PKI technology.  This capability allows Federal agencies to digitally sign documents in a PKCS #7 format and send to the Office of the Federal Register electronically instead of providing the original paper document, two certified paper copies, and an electronic version on disc resulting in potential cost savings to the agency, as well as a significant reduction in the amount of paper used in the publication process.  In recent years, more agencies have adopted this method of submission.  The Office of the Federal Register encourages all agencies to use the digital submission process.
