The American artist Marc Lombardi (1951-2000) produced visual networks and diagrams that made visible the hidden connections between political and economic processes, corporations, and individuals. This notebook does not feature his well-known delicate drawings and networks, but reveals his research and thinking material. The former librarian Lombardi, known for his meticulousness, sorted and archived his material, drawn from publicly accessible media sources, through a system of index cards, reprinted here. In her introduction, Carolyn Christov-Bakargiev describes her personal experience of that outstanding artistic oeuvre, whose lines and connections are subordinated to the facts of financial scandals, terror attacks, and (economic) crime, while revealing names.
