Preserving information in a digital age: What's the difference?

Summary Until the mid-twentieth century, paper was the dominant medium for recording, transmitting and storing information. However, storage of information is now nearly 100% in digital format with only a miniscule 0.003% of the world's information being produced as print on paper. Because digital information is being produced so much more rapidly than other forms, libraries of the future will inevitably be libraries of digital content. A significant change has taken place. The preservation of information in digital format is emerging as a key concern of organizations including libraries. After a decade of discussion, the major libraries in the technologically advanced regions of the world are moving to establish policies, a technological infrastructure, and operational programmes in digital preservation. Many of these initiatives are cross-sectorial partnerships between libraries, archives, universities and business. Readers of The Paper Conservator are one group who has the background and orientation to comprehend how digital information may be preserved. To be key players, however, they need to understand its dynamics and difficulties. With the intention of building a shared commitment to action, this paper identifies and defines the key issues facing libraries and creates a shared awareness of trends and activities. Readers are also challenged to identify gaps, come forward with examples of digital preservation in practice, and identify opportunities for action.
