Abstract: From dictionaries to gazetteers, the early modern period was the age of the reference book, with more than 1,600 guides published between 1470 to 1599 alone. Itinerary books structured European conceptualization and navigation of space through the eighteenth century, yet have rarely been studied as a text technology and international knowledge project. The EmDigIt database represents the first attempt at a comprehensive bibliography, and currently consists of eighty-four itinerary books representing over 3,500 unique routes, connecting over 1,500 locations, published and republished over the course of two centuries. The talk will cover applications of Social Network Analysis in a forthcoming article for the Journal of Social History, as well as next steps for the project using the Transkribus text recognition software.
