CM provides for near-term preservation without handling long-term preservation, which must overcome risks associated with technological obsolescence and fading human memory. This article offers a solution to mitigate these risks. Implementing the needed software would be a small addition to widely deployed CM offerings. This long-term preservation solution, devised for cultural and scholarly digital documents, is already structured to support archival principles for business records, and the article describes this Trus...
