The Digital Library Federation

 

On May 1, 1995, 16 institutions created the Digital Library Federation (additional partners have since joined the original 16). The DLF partners have committed themselves to "bring together—from across the nation and beyond—digitized materials that will be made accessible to students, scholars, and citizens everywhere." If they are to succeed in reaching their goals, all DLF participants realize that they must act quickly to build the infrastructure and the institutional capacity to sustain digital libraries. In support of DLF participants' efforts to these ends, DLF launched this publication series in 1999 to highlight and disseminate critical work.

Foreword

Access to digital materials continues to be an issue of great significance in the development of digital libraries. The proliferation of information in the networked digital environment poses challenges as well as opportunities. The Digital Library Federation is committed to fostering work that addresses these challenges and opportunities while also ensuring the timely dissemination of information about state-of-the-art initiatives.

The author reports on a wide array of activities in the field. While this publication is not intended to be exhaustive, the reader will find, in a single work, an overview of systems of knowledge organization and pertinent examples of their application to digital materials. Technological developments have made it possible to provide alternate subject access through the adoption and use of multiple knowledge organization schemes. The report offers extensive practical information for institutions embarking on digital library initiatives. In particular, the section on planning and implementing organization systems identifies methods for enhancing access to existing digital materials.
