A History of the ARPANET: The First Decade
A 1981 technical history of the ARPANET, the early US military computer network, compiled by the Defense Technical Information Center and covering its first decade of planning and operation. The pictures are plain line maps of the United States showing network nodes such as UCLA, SRI, Utah, Illinois, Carnegie and BBN joined by straight connecting lines, with dense clusters of sites in California and the Boston area, which a designer might use as a schematic of linked hubs spread across a continent.
