 When the Army's needs outgrew the capacity of the former theater, several of the units were moved in 1887 to a new building, the Army Medical Museum and Library, on the nearby National Mall (7th Street and South B Street [now Independence Avenue], SW, the present site of the Smithsonian's Hirshhorn Museum).In 1922, the library was renamed the "Army Medical Library" (AML).In 1927, using funds from the Carnegie Museums of Pittsburgh, "Index Medicus" merged with the "Quarterly Cumulative Index" forming the "Quarterly Cumulative Index Medicus".
