e-Journals: Archiving and Preservation. Briefing Paper. JISC. March 2007.

The traditional model of publishers supplying content and libraries preserving content does not work well with digital materials. Licensing agreements do not guarantee permanent access to materials. But the e-journal trend is increasing at a rapid rate. Many are searching for the solution. The terms ‘perpetual access’, ‘archiving’, and ‘long-term preservation’ are often used interchangeably. Perpetual access is usually used with e-journal licenses clauses to assure that access will be continued regardless of events. Archiving describes the management processes of e-journals. Long-term preservation refers to the processes to ensure the content remains accessible in the future, regardless of any technical or organizational changes. There needs to be multiple options and strategies for preserving e-journals, including coordinated overlap. There are promising developments evolving, but the solutions must include libraries, publishers, and archiving services.

Metadata for All: Descriptive Standards and Metadata Sharing across Libraries, Archives and Museums. Mary W. Elings, G√ľnter Waibel. First Monday. 5 March 2007.

The cultural heritage community has a large pool of digital resources for teaching, research and learning. A big challenge is integrating digital content from libraries, archives and museums which use different strategies for caring for their materials. Applying data content standards by material type rather than the organization could make the data more usable within the entire community. Two schema used are Visual Resources Association (VRA) Core and the Categories for the Descriptions of Works of Art (CDWA). The article lists the elements of metadata standards, and the relationship between them and museums, libraries and archives. There is a call among archives to process collections more efficiently so they achieve control over all their holdings. The successful use of digital materials in libraries, museums, and archives revolves around the ability to describe similar materials in different institutions.

A Digital Life. Gordon Bell, Jim Gemmell. Scientific American. February 18, 2007.

New systems may allow people to record everything they see and hear--and even things they cannot sense--and to store all these data in a personal digital archive. The MyLifeBits project has provided the tools to create a person’s lifelong digital archive. Technological advances may make this easier but there are challenges, particularly with privacy rights and restrictions. They believe digital memories will yield benefits in many areas.
