In June 2012, it reopened to visitors after a major two-year restoration project which restored and improved the building's historic spaces, increased accessibility, and brought the building's aging infrastructure and facilities up to date. More than 1,000 National Academies staff members work at The Keck Center of the National Academies at 500 Fifth Street in northwest Washington, D.C. The Keck Center provides meeting space and houses the National Academies Press Bookstore. The Marian Koshland Science Museum of the National Academy of Sciences – formerly located at 525 E St., N.W. – hosted visits from the public, school field trips, traveling exhibits such as Mathemalchemy, and permanent science exhibits. The NAS also maintains conference centers in California and Massachusetts. The Arnold and Mabel Beckman Center is located on 100 Academy Drive in Irvine, California, near the campus of the University of California, Irvine; it offers a conference center and houses several NAS programs. The J. Erik Jonsson Conference Center located at 314 Quissett Avenue in Woods Hole, Massachusetts, is another conference facility.
