44 U.S.C. § 741: Disposition of documents stored at Capitol

The Secretary and Sergeant at Arms of the Senate and the Clerk and Doorkeeper of the House of Representatives, at the convening in regular session of each successive Congress shall cause an invoice to be made of public documents stored in and about the Capitol, other than those belonging to the quota of Members of Congress, to the Library of Congress and the Senate and House libraries and document rooms. The superintendents of the Senate Service Department and House of Representatives Publications Distribution Service shall put the documents to the credit of Senators and Representatives in quantities equal in the number of volumes and as nearly as possible in value, to each Member of Congress, and the documents shall be distributed upon the orders of Senators and Representatives, each of whom shall be supplied by the superintendents of the Senate Service Department and House of Representatives Publications Distribution Service with a list of the number and character of the publications thus put to his credit, but before apportionment is made copies of any of these documents desired for the use of a committee of either House shall be delivered to the chairman of the committee. Four copies of leather-bound documents shall be reserved and carefully stored, to be used in supplying deficiencies in the Senate and House libraries caused by wear or loss.
