Abstract
The aim of legal deposit is to ensure the preservation of and access to a nation’s intellectual and cultural heritage over time. There is a global trend towards extending legal deposit to cover digital publications in order to maintain comprehensive national archives. However, including digital publications in legal deposit regulations is not enough to ensure the long‐term preservation of these publications. Indeed, there are many practical difficulties associated with the entire deposit process. Conceptsm, principles and practices that are accepted and understood in the print environment, such as publication, publisher, place of publication and edition, may have new meanings or no longer be appropriate in a networked environment. Mechanisms for identifying, selecting and depositing digital material either do not exist or are inappropriate for some kinds of digital publication. There is a great deal of work on developing digital preservation strategies; this is at an early stage. National and other deposit libraries are at the forefront of research and development in this area, often in partnership with other libraries, publishers and technology vendors. Most of this activity is of a technical nature. There is some work on developing policies and strategies for managing digital resources. However, not all management issues or users’ needs are being addressed.
