Communications, transportation, and commerce have been inextricably intertwined since the beginning of human history until quite recently, and they still remain closely related today.

“The success of the first electronic telegraph line in 1844 opened an era of modern communication in America. Before the telegraph there existed no separation between transportation and communication. Information traveled only as fast as the messenger who carried it.” Media and the American Mind (Czitrom, D. J., 1982)

This reality was even codified in the Dewey Decimal library classification system: 380 Commerce, communications, transportation
See also transportation and commerce


These are organized by a classification scheme developed exclusively for Cosma. More…
