We can exploit the preservation advantages of microfilm today, and the access advantages of digital technologies tomorrow. We can transmit the scanned digital images to distant computer workstations for viewing, and we can print out high-quality paper facsimiles whenever and wherever they are needed. Let me assure you that the nation's investment in microfilming for preservation continues to be a wise investment. It does not preclude exploiting the advantages of digital access today, nor at any time in the future. The second hurdle to be overcome underscores this choice.
Technology changes rapidly.
The forms in which data are stored are also continuing to change. Standards are still evolving. As a result we cannot guarantee that images scanned and stored in digital form today will be accessible even five years from now, let alone five hundred, any more than today we can easily read the punched cards of yesterday. We still have much to learn about the best ways to store. Rapid progress is being made, both in the private and higher educational sectors.
