Why is Incorporation by Reference Used?

Incorporation by reference is used primarily to make privately developed technical standards Federally enforceable. Agency generated documents are presumptively ineligible for incorporation by reference because that material can and should be published in full text in the Federal Register and CFR. Agencies are not authorized to incorporate by reference material on their web sites as a substitute for Federal Register publication.

The legal effect of incorporation by reference is that the material is treated as if it were published in the Federal Register and CFR. This material, like any other properly issued rule, has the force and effect of law. Congress authorized incorporation by reference in the Freedom of Information Act to reduce the volume of material published in the Federal Register and CFR. (See 5 U.S.C. 552(a) and 1 CFR part 51). Congress gave complete authority to the Director of the Federal Register to determine whether a proposed incorporation by reference serves the public interest.
