20 U.S. Code § 51 - Library
R.S. § 5587 derived from act Aug. 10, 1846, ch. 178, § 8, 9 Stat. 105.
Under provisions of R.S. § 94 and act Mar. 3, 1875, ch. 179, 18 Stat. 512, the Joint Committee on the Library of Congress was authorized to extend the use of the Library to the Regents of the Smithsonian Institution. These provisions were not classified to the Code, being rendered superfluous by a general declaration of public policy by Congress, by a joint resolution adopted Apr. 12, 1892, 27 Stat. 395, to the effect that facilities for study and research in the Library of Congress, the National Museum, and similar institutions shall be afforded investigators, students, etc., in the several states and territories as well as in the District of Columbia.
