The library launched a mass deacidification program
Washington D.C., U.S.
Under Billington, the library launched a mass deacidification program in 2001, which has extended the lifespan of almost 4 million volumes and 12 million manuscript sheets; and new collection storage modules at Fort Meade, the first opening in 2002, to preserve and make accessible more than 4 million items from the library's analog collections.
