Historic images are in demand—especially those available for discovery online. At the same time, digitizing large photograph collections can be daunting, particularly when a project involves balancing access and preservation with tight budgets, limited staff, and fragile or deteriorating objects. Outside collaborators can help leverage available resources and increase the effectiveness and reach of the project but identifying and recruiting partners and keeping diverse stakeholders on the same page can be challenging. Panelists will discuss collaborating across disciplines on two large digitization projects, the Religious News Service photographs, 1945-1982 (about 60,000 prints and negatives) and the Los Angeles Department of Public Works photographic materials (about 700,000 prints, negatives, and slides).
