Digitization is allowing greater access to archival documents that have not been published before for scholars, independent and affiliated, who may not be able to geographically travel to the location of the archival repository, or afford to reside nearby the archive for research or receive a grant to do so. This revolutionary technology of digitization is therefore leveling the playing field allowing for scholars out of the blue, many independent and unafilitated with institutions or from far away geographical home locations, to publish seminal work using unpublished archival documents. Archival documents are primary resources and allow for more original scholarship than only relying on published materials.
