MAJ.-GEN. WILLIAM TECUMSEH SHERMAN TO DIVISION COMMANDERS, DECEMBER 23, 1862.
The Geography and Map Division maintains more than one hundred individual collections that have been acquired through gifts, government transfers, and purchases or assembled by division specialists according to common themes. In addition, the Vault Map Collection includes some three thousand manuscript and rare printed maps that have been filed together for their intrinsic, artistic, or historical significance. With few exceptions, these collections are stored in a specially designed vault equipped with temperature and humidity controls.
An assortment of Special Collections material can be found in the tabs to the left, organized by geographic area, as well as two categories for military maps and special format maps.
