ministrative Committee of the Federal Register, approved by the President
October 11, 1948 (13 F. R. 5935; 1 CFR Part 2), under the authority con-
tained in section 11 (f) of the Federal Register Act as amended (67 Stat.
388; 44 U. S. C. 311 (f)). The contents of the Federal Register and of
the Code of Federal Regulations are by law prima facie evidence of the text
of the original documents and are required to be judicially noticed (49 Stat.
502, 67 Stat. 388; 44 U. S. C. 307, 311 (e)). The approved citation of the
Code is “CFR.” Thus the citation “39 CFR 1.1” refers to Section 1.1
of this Title.
A General Preface to the Code of Federal Regulations appears in the
volume containing Titles 1-3 and also in the General Index volume.
