Infrastructure, Representation, and Historiography in BBN's Arpanet Maps

The earliest and most widespread representation of the Arpanet were network graphs or maps that, arguably, remain its most prominent artifact. In an earlier article, the authors analyzed how the maps were created, what they represented, and how histories of the network parallel their emphases and omissions. Here, the authors begin a retooling of the maps to highlight further what is missing from them: communication flows, gateways to other networks, and hierarchies between its nodes.
