As part of our ongoing work with the Northwestern University Archives and Northwestern University Library Digital Collections we get the opportunity to do some really great digitization projects. This was a single one off project, but the digitized object is one of very interesting historical significance to Evanston, the location of one of the NU campuses. The 1876 map had significant conservation work done before it was imaged by NUIT A&RT NUAMPS employees Stefani Foster and Dave Look. Stefani appears in the video below.
The map in all of its high resolution conserved glory can be seen on the NUL website: http://www.library.northwestern.edu/archives/exhibits/map/index.html
