AbstractConceptual modeling of bibliographic data, including the FR models and the consolidated IFLA LRM, has provided an opportunity to shift focus to entities and relationships and to support hierarchical work-based exploration of bibliographic information. This paper reports on a study examining the complexity of a work's bibliographic family data and user interactions with data visualizations, compared to traditional displays. Findings suggest that the FRBR-based visual bibliographic information system supports work families of different complexities more equally than a traditional system. Differences between the two systems also show that the FRBR-based system was more effective especially for related-works and author-related tasks. 相似文献

Abstract Increased use of geographic information systems on college and university campuses has prompted libraries to ask the question: Where and how can libraries fulfill these digital needs? This paper describes the actions taken by the Syracuse University Library to implement GIS and geo-spatial data services to the University community. Discussion will focus on the planning, administration, public services, collection development, and management issues pertaining to a networked multi-Station GIS lab. 相似文献

Geographic information sources have evolved at the same rate as the many other information sources in the last half a century. This article discusses geographic literacy and spatial thinking, and the questions that derive from geographic inquiry. Librarians in academic libraries are most often called on to meet the complex specialized geographic information needs that arise from study and practice in those areas. The sources we use and the ways we respond to these needs have evolved and expanded with the advent of various digital technologies. In order to be able to work with these new technologies, librarians can develop specialized competencies in geographic information systems (GIS) which allow them to go beyond print maps and atlases in the provision of geographic information. 相似文献

The United States National Library of Medicine (NLM) TOXNET® databases <http://toxnet.nlm.nih.gov> provide broad coverage of environmental health information covering a wide variety of topics, including access to the U.S. Environment Protection Agency (EPA)'s Toxics Release Inventory (TRI) data. The NLM web-based geographic information system (GIS), TOXMAP® <http://toxmap.nlm.nih.gov/>, provides interactive maps which show where TRI chemicals are released into the environment and links to TOXNET for information about these chemicals. TOXMAP also displays locations of Superfund sites on the EPA National Priority List, as well as information about the chemical contaminants at these sites. This column focuses on a new version of TOXMAP which brings it up to date with current web GIS technologies and user expectations. 相似文献

The goal of our research project is to explore the use of new technologies in providing more sophisticated delivery systems for information services in situations where the services of skilled reference librarians are not available. We are working on developing an advanced function workstation equipped with a CD-ROM jukebox of reference books and vocabulary control tools on laser dlsks with keyword access. The user interface will include an expert system to guide users in selecting the types of material best suited to their needs. It will also provide guidance in developing the best search strategy by mapping the terms selected by the users to the more controlled vocabularies of the data bases. Searches that are too broad and yield too much material will be narrowed. Conversely, searches that are too specific will be broadened. The system will also be designed to connect to a full service integrated library network also enabling the user to access the on-line card catalog, check circulation and do interlibrary loans. In developing this system we will be taking advantage of many new technologies including the advanced function workstations, expert systems components, hypertext and optical disk storage. 相似文献

Through a nationwide survey of potential public library closures from 1999–2003 (the most recent federal dataset at the time of the study), the researchers assessed the reasons for public library closure, actions taken to alleviate possible loss of library services and resources, and the potential effects on users from the librarians' perspective. Geographic information systems (GIS) was used to analyze the demographics and socioeconomics of the geographic market areas around permanently closed library facilities and compared with national averages from the 2000 U.S. Census. The study found a variety of factors lead to closure; however, a lack of use, a sudden reduction in funding, and the opening of another library facility were the most common closure reasons. The actions taken by the community or library system to alleviate the loss of library services and resources depended on the circumstances of each closure. The geographic market areas around permanently closed facilities tended to include poorer and less educated patrons, and more renters than homeowners when compared to the national average from the 2000 U.S. Census. The study presents a methodology using GIS to describe libraries' geographic market areas and illustrates the need for further exploration into reasons for public library closures and the effects of facility site location, relocation, and permanent closure on potential users. 相似文献

如今,战略性新兴产业已经提升到国家战略地位。从产业层面上来看,因为产业信息资源是企业层面信息资源的集合,所以产业层面的信息需求具有更多的共性。本文通过厘清战略性新兴产业共性化信息需求块资源模型、机理结构模型和三维驱动模型,来分析战略性新兴产业共性化信息需求机理。文章提出了产品数据信息、运营数据信息、用户需求数据信息和品牌数据信息块资源模型。在其结构关系中,产业和企业的持续发展,最基本的结构元素是"产品"。因此,以产品为核心的信息需求则成为结构机理的核心要素。在驱动关系中,用户需求驱动、效益驱动和网络结构凝聚驱动三维驱动模型驱动着信息需求在产业-企业-产品-用户的结构模型中服务于产品。基于所提出的模型,本文以战略性新兴产业专业知识服务系统为例,为系统完善提出未来发展的建议,旨在为我国战略性新兴产业相关信息资源服务平台提供依据和参考,进而推动战略性新兴产业的运行与发展。 相似文献

Programs for geospatial support at academic libraries have evolved over the past decade in response to changing campus needs and developing technologies. Geospatial applications have matured tremendously in this time, emerging from specialty tools to become broadly used across numerous disciplines. At many universities, the library has served as a central resource allowing students and faculty across academic departments access to GIS resources. Today, as many academic libraries evaluate their spaces and services, GIS and data services are central in discussions on how to further engage with patrons and meet increasingly diverse researcher needs. As library programs evolve to support increasingly technical data and GIS needs, many universities are faced with similar challenges and opportunities. To explore these themes, data and GIS services librarians and GIS specialists from five universities—the University of North Carolina at Chapel Hill, Texas A&M, New York University, North Carolina State University, and California Polytechnic State University—with different models of library geospatial and data support, describe their programs to help identify common services, as well as unique challenges, opportunities, and future plans. 相似文献

This paper discusses issues relating to the organization of a campus wide information system which is based upon the Gopher protocol. In an effort to develop guidelines for both collection developnent and classification of Gopher resources, the Library undertook a study of, what is popularly b w n as, Gopherspace. The results of that study provide an overview of various Gopher models and their pwpose., the types of resources typically found on campus wide information systems which use the Gopher protocol, and the ways in which Gophers are urganized The paper concludes with recommendations for the development of coherent collection development policies and organizational schemas which reflect the primary user community's needs and interests. 相似文献

Is your library market-driven, product-driven or customer-driven? New internet-based data and tools are now available for public libraries that enable you to be customer-driven—for your own unique service area. This article shows how three library systems are using these tools—focused on market segmentation data and geographic information system (GIS) technology—to deliver more relevant customer services. Each solution described in the article was developed in close collaboration between CIVICTechnologies and the library, involving research to understand the library's objectives and desired outcomes, and using the data needed to meet each library's unique challenge. 相似文献
