The Administrative Committee of the Federal Register (ACFR) has the authority under 44 U.S.C. 1510 to regulate the collation and republication of the Code of Federal Regulations (CFR) with the aim of keeping it as current as practicable. Until recently, it has not been economically practical to update the CFR more frequently than once per year. With the advent of web-based publication formats, the ACFR has requested that the Office of the Federal Register (OFR) and the Government Publishing Office (GPO) develop and maintain the e-CFR as an authoritative informational resource, which will serve as the model for a currently updated, official edition of the CFR.
