The preservation of scientific data is a complex task, both in theory and in practice. This article examines the major producers of U.S. federal government scientific technical information (STI), principal data categories, and the role of the National Archives in documenting scientific data. The preservation of scientific data by the National Archives and Records Administration (NARA) is a monumental task in both volume and complexity of the data and the issues involved. This article will examine several important questions surrounding the appraisal, accessioning, and preservation of scientific data by NARA. 相似文献

Abstract The Center for Electronic Records of the National Archives is the unit of the National Archives and Records Administration responsible for the appraisal, accessioning, preservation, and provision of access to the permanently valuable electronic records of the Federal government. Recent changes in technology, especially the development of global networks of computers, have changed the way some archivists view the role of archives, especially for electronic records. From a reference services perspective, there is a continuing rqle for electronic records archives. 相似文献

ABSTRACT Scholars working in the fields of medieval history and cultural history have recognized that understanding the cataloging and accessioning of books is central to understanding the transmission of ideas. This view should come as no surprise to catalogers themselves, who daily struggle with the problem of providing intellectual, and sometimes physical, access to texts and information. Unfortunately, general histories of libraries and even the library literature seem content to sketch out a chronological development of cataloging in line with the nineteenth and twentieth century view of library development, from a simple list to complex intellectual systems. In truth, however, those individuals responsible for cataloging books in medieval libraries faced many of the same challenges as catalogers today: how to organize information, how to serve local needs, and how to provide access to individual works within larger bibliographic formats. This article will summarize recent scholarship in the history of the book that relates to library cataloging, as well as providing parallels to the cooperative library environment of today. 相似文献

The phrase “peace, order and good government,” common to the definition of federal powers in both the Australian and the Canadian
constitutions, has defined the relationship of the Crown and the citizen for more than five centuries. The archival record
is fundamental to that relationship, providing its authoritative legal basis, documenting its evolution and continuing as
a reminder of both our proudest achievements and our most dismal failures as a society. This paper reflects on the role of
archives in recent Canadian human rights issues, highlighting both the strengths and the weaknesses of the record, the perception
of archives as an agency of the state and the role of archives in helping society address highly contentious issues. 相似文献

This article describes work done at Indiana University to “batch load” data from MARC bibliographic and authority records into the Work-based and FRBR-like Variations system. A series of experiments to iteratively refine our batch loading algorithm is described, along with details of how the algorithm identifies Works, creates relationships between entities, and maps a large amount of data from MARC into Variations records. The article closes with a discussion of the potential impact of this work on Variations project workflow and community FRBRization activities. 相似文献
