The problem of preserving digital information and the strategies that are and might be employed to address it are the focus of this fifth issue of "Transforming Libraries." Twenty-one individuals involved at the technical or policy level in developing strategies for preserving digital information were interviewed. There is consensus on a number of points, including: the problem is growing faster than solutions are being worked out; often confusing is the difference between digitizing for preservation and digitizing for access, and preserving digital-only information; and more analysis of the problem, including further assessment of the technical issues, costs, options, and risks needs to be undertaken in a collaborative manner. Ten stakeholder groups who will play a role in designing and testing possible models are: researchers or originators of information; publishers; repositories; libraries and museums; the national libraries and archives who operate legal deposit programs; the cooperative service agencies; private storage providers; the scholarly associations; indexing and abstracting services; segmented market providers; and certified digital archives as proposed in a study by the Commission on Preservation and Access and the Research Libraries Group. The "Reports from the Field" section of this document features some of the varying institutional approaches to preserving digital information. (AEF)
