“The Legislative Branch Appropriations Act 2010 (P.L. No. 111-68) amended 2 U.S.C. 104(a), to require the posting of the semiannual report of the Secretary of the Senate on the Senate Web site. Since 1823, the Secretary of the Senate has published the semiannual statements covering the periods from October 1st to March 31st and April 1st to September 30th of each year. The first online report begins with the reporting period of April 1, 2011 to September 30, 2011. You may view the two volumes in a single file or in two separate files that correspond to the published version. The files have been digitally signed by the U.S. Government Printing Office (GPO). The technology used to certify these documents allows GPO to secure the data integrity and provides users with assurance that the content is unchanged since it was disseminated by GPO.
