Mapping History at the University of Illinois

Digital Surrogates for the maps belonging to Mapping History at the University of Illinois: A Digital Humanities project. DCC is performing the digitization of the maps for this joint project between Archives and the Map Library.

This project will take a multilayered approach to telling the history of the University within an overarching narrative that integrates the idea of place via maps, 3D imagery, and archival content. A project web portal will enable users to: explore University history through decades and themes; overlap and manipulate maps from different time periods; and activate a moving timeline visually illustrating how the University’s built environment has changed. It will include a digital repository of University and Champaign-Urbana maps held across Library units and by

Facilities and Services (F&S). Completed in time for the University’s Sesquicentennial in spring

2017, Mapping History at the University of Illinois will harness cutting edge technology to introduce our rich history in innovative ways to new and old audiences of students, faculty, administrators, and the public.
