Digital archives accept and preserve digital content for long-term use. Increasingly, stakeholders are creating large-scale digital repositories to ingest surrogates of archival resources or digitized books whose intellectual value as surrogates may exceed that of the original sources themselves. Although digital repository developers have expended significant effort to establish the trustworthiness of repository procedures and infrastructures, relatively little attention has been paid to the quality and usefulness of the preserved content itself. In situations where digital content has been created by third-party firms, content quality (or its absence in the form of unacceptable error) may directly influence repository trustworthiness. This article establishes a conceptual foundation for the association of archival quality and information quality research. It outlines a research project that is designed to develop and test measures of quality for digital content preserved in HathiTrust, a large-scale preservation repository. The research establishes methods of measuring error in digitized books at the data, page, and volume level and applies the measures to statistically valid samples of digitized books, adjusting for inter-coder inconsistencies and the effects of sampling strategies. The research findings are then validated with users who conform to one of four use-case scenarios: reading online, printing on demand, data mining, and print collection management. The paper concludes with comments on the implications of assessing archival quality within a digital preservation context. 相似文献

ABSTRACTThe institutional repository (IR) can provide a system for digitizing print serials for online delivery and a way to archive and preserve serial content already available online. Organizing serial content in IRs varies based on the architecture of each repository. In this presentation, Kay Teel of the Metadata Department at Stanford University Libraries discussed different approaches IRs use to manage serial content. She gave examples illustrating the inconsistent treatment of serials in the Stanford Digital Repository (SDR) and described a conceptual model for serials in the SDR to provide an improved user experience finding and accessing digital serial content. 相似文献

Cooperative organization has been proposed as a means to improve the usefulness of virtual libraries. Information interchange among library and other academic applications is often hindered by the lack of application interoperability. This hindrance may be overcome through the development of standards that allow for digital libraries to exchange and share information with other applications. The Graduate Program in Production Engineering (PPGEP) of the Federal University of Santa Catarina (UFSC) launched its Theses and Dissertations Bank (BTD) in 1995. BTD is possibly the first online academic digital library of theses. From a digital document repository, BTD evolved into a system that combines bibliometry and informetry features. BTD is used by students and faculty in their research activities, but also by decision makers from industry and academia. They use it, respectively, to search for specialists and to measure interest and knowledge interchange among PPGEP research areas. This article presents the history, features, and development prospects for the BTD project. The integration of BTD with other academic applications, especially those of the Brazilian national science and technology platform, is emphasized. 相似文献

This article examines whether implementing visualizations on an institutional repository webpage increases traffic on the site. Two methods for creating visualizations to attract faculty and student interest were employed. The first is a map displaying usage of institutional repository content from around the world. This map uses Tableau software to display Google Analytics data. The second method is a text mining tool allowing users to generate word clouds from dissertation and thesis abstracts according to discipline and year of publication. The word cloud uses R programing language, the Shiny software package, and a text mining package called tm. Change in the number of institutional repository website sessions was analyzed through change-point analysis. 相似文献

The aim of this research study is to examine the functionality development of the open source repository system: DSpace. The data on DSpace repositories' implementation practices were collected from the DSpace User Registry during September 2013–March 2014. A total of 545 repositories in the registry indicated specific system function customizations, representing 533 unique institutions from 95 countries worldwide. The findings indicate that U.S.A. and India are the top two countries to have adopted DSpace. The majority of the DSpace digital repositories are created by academic institutions, which indicates a strong representation of academic institutions in the use of DSpace. The major adopted system functions are statistics, Dublin Core Meta Toolkit, Manakin Themes, and language packages. Most DSpace members use the repository system as their institutional and learning resource repositories. The top content types are conference papers, research documents, and learning/teaching materials. The implications of the findings are also discussed. 相似文献

Because of its commitment to keeping the digital contents accessible, institutional repository plays an important role in the long-term preservation of intellectual output of the institution. However, digital preservation in institutional repository is faced with severe legal issues, especially the intellectual property problems. This paper focuses on the copyright issues involved with long-term preservation of digital resource in institutional repositories. It begins with a brief introduction to the relationship between the institutional repository and digital preservation. Based on this background information, the paper analyzes the related laws and regulations in China that affect the long-term preservation of digital resource in institutional repository. Then the authors discuss in details what kind of the copyright risk there may be, if we realize the long-term preservation of digital resource in institutional repositories. There may be different legal hazards, according to the various types of the digital output collected by institutional repository. The paper ends up with several suggestions to avoid the legal risk in digital preservation of institutional repository. Firstly, to utilize fair use is a feasible way. Secondly, also most safely, is to get the permission from the copyright owner. This is involved in the long-term preservation contract and open license. 相似文献

充分诠释社交媒体平台的档案特质有助于形成更加成熟可行的社交媒体信息档案化管理方案,亦可推进档案管理理论与方法的数字转型。本文以理论构建的方法从社交媒体档案库的形成基础、档案特性、新特征三个层面逐级推导社交媒体平台作为档案库的内涵及特点。本文论证了社交媒体平台可被视作档案库这一提法,并提出形成的社交媒体档案库是基于社交媒体活跃的信息活动构建的信息资源库,因其具有档案价值和日益普遍的档案化管理行为而实现档案库的建构,这个档案库亦从时空、主体、关联性以及价值等方面呈现新特征,由此成为档案管理数字转型的重要阵地。 相似文献

Institutional repositories (IRs) are important research management tools that can give increased visibility to the institution’s scholarly outputs. Although statistics were previously available through the various repository interfaces, without an agreed standard it was not possible to measure usage across a range of IRs accurately. IRUS-UK is a national aggregation service, containing details of all content downloaded from participating IRs in the United Kingdom. Through collecting raw usage data and processing them into item-level usage statistics IRUS-UK provides comparable and authoritative standards-based data and also acts as an intermediary between UK repositories and other agencies. 相似文献

This article describes children's use of networked technology in three branches of an urban public library. Direct observations of their use of computers and data gathered from brief interviews with them were recorded using personal digital assistants (PDAs). Findings suggest that (1) the largest proportion of children's use of computers is for access to games, (2) use of computers for communication purposes (e.g., chat, e-mail, and word processing) is minimal, and (3) repeat use of the computers varies by branch. Grade level analysis reveals that middle school students access games less than elementary students do at two branches and that middle school students use the computers more than elementary students do for communication purposes. Overall, girls and boys use games, chat, and e-mail in comparable proportions. In other categories of use, there are gender differences but no consistent pattern emerges across branches. This investigation provides a first view of children's unmediated use of technology in the public library, their reasons for using library computers, and provides baseline data for assessing the outcomes of technology programs and services developed by the library to serve the needs of this user group. 相似文献
