creators: Umar Qasim Sharon Farnel John Huck
abstract: Rapid changes in the field of technology and exponential increase in the volume of digital content makes long-term preservation of institutional resources a challenging task. Digital preservation requires a commitment for applying preservation actions along with continuous monitoring and management of the preserved resources. The expense of these actions mean that a memory institution needs to make choices about what level of preservation it can afford to provide for a resource when it makes a commitment to preserve it. This paper presents a tiered model to determine preservation levels for digital content, based on an assessment that considers three factors: type of resource, archival responsibility, and projected preservability of the resource (TAP). The paper presents a practical, exible approach to a complex set of factors and includes examples of how the model can be applied at an academic library.
