This paper reports results of an exploratory quantitative analysis of metadata versioning in a large-scale digital library hosted by University of North Texas. The study begins to bridge the gap in the information science research literature to address metadata change over time. The authors analyzed the entire population of 691,495 unique item-level(More)
Preserving long-term access to digital information resources is one of the key challenges facing libraries and information centers today. The University of North Texas (UNT) Libraries has entered into partnership agreements with federal and state agencies to ensure permanent storage and public access to a variety of government information sources.

Maintaining usable digital collections necessitates maintaining high quality metadata about those digital objects. An effective metadata management approach can help institutions improve consistency, clarity of data lineage and relationships so that institutions can better use, reuse, and integrate resources. The metadata quality characteristics depend on(More)
The synergies of numerous emerging trends such as the development of open source software, global and explosive growth of social networking, interinstitutional data sharing, cross discipline collaborations, etc. provide new directions for scholarship. The rapid pace of development poses new threats and challenges to scholarly communication as well. Open(More)

In a metadata management context, change could mean to transform, substitute, or make the content of a metadata record di®erent from what it is or from what it would be if(More)
Important products in an academic library's collection are Masters Theses and Doctoral Dissertations since they represent a wealth of scholarly and artistic content created by Masters and Doctoral students in the degree-seeking process. Each has experienced an evolution to a new format, electronic. Many of these are PDF files, using the Adobe Acrobat(More)
In the last decade, a growing body of the scholarly information and instructional materials produced by universities existed primarily in digital format. New digital technologies increased the productivity of scholars. The purpose of an Institutional repository (IR) is to manage their scholarly work in ways that facilitate interdisciplinary collaboration,(More)
Authors in the library science field disagree about the importance of using costly resources to create local metadata records, particularly for scholarly materials that have full-text search alternatives. At the University of North Texas (UNT) Libraries, we decided to test this concept by answering the question: What percentage of search terms retrieved(More)
