Rationale to support a proposed methodology to evaluate cost
models
The cost to preserve electronic materials is The cost to preserve electronic materials is expected to be highexpected to be high
Cost models facilitate the decision-making Cost models facilitate the decision-making process process
Should be able to evaluate cost models and Should be able to evaluate cost models and frameworks across the models frameworks across the models
Use the information to support the choice of Use the information to support the choice of preservation strategy or suite of p. strategiespreservation strategy or suite of p. strategies

How does this fit into the larger picture of digital preservation?
Now is the time…to develop a strategic plan Now is the time…to develop a strategic plan for the future to assure access to preserved for the future to assure access to preserved digital and born-again digital materials over digital and born-again digital materials over timetime
