[Excerpt] In 2014, the Dalhousie University Archives began its first archival mass digitization project with the Elisabeth Mann Borgese fonds. The successful completion of this project required the project team to address both broad and specific technical and intellectual challenges, from rights management in an online access environment to the durability of the equipment used. To best understand the challenges faced, there will first be a brief introduction to the fonds and project goals of balancing preservation and access before moving on to a discussion of these challenges in further detail, and finally, concluding with a discussion of some considerations, best practices, and lessons learned from this project.
