The National Archives announced this week that effective Friday, its record rooms for researchers and exhibits of the U.S. Constitution, Bill of Rights, Declaration of Independence and other famous documents will be open  to the public for fewer hours.

The cut to service is another result of sequestration, the across-the-board federal spending reductions that took effect March 1.

“We don’t take these reductions lightly,” Archivist of the United States Davis S. Ferriero said in a statement announcing the reduced hours.

The Archives building in downtown Washington will no longer offer extended exhibit hours until 7 p.m. seven days a week, from March through Labor Day. Until further notice, the building will open to the public from 10 a.m. to 5:30 p.m, seven days, year-round.

Research rooms in Washington and the campus in College Park, Md., also will halt extended hours until 9 p.m. three days a week. The public will now have access year-round from 9 a.m. to 5 p.m., Monday through Saturday.
