The document summarizes the findings of a survey conducted by the Blue Ribbon Task Force on Sustainable Digital Preservation and Access. The survey aimed to understand the requirements for long-term digital preservation of materials over 100 years. Key findings include that stakeholders like government agencies, universities and libraries need to preserve materials like source files, databases and emails for over 50 years. Current practices are inadequate and at risk of losing information long-term due to issues like lack of standards around migration and high costs of manual processes. Collaboration between different stakeholders is needed to develop best practices for long-term digital preservation.
