数字图书馆评估模式探讨 总被引：3，自引：0，他引：3
由于数字图书馆的实际情况,互联网数字图书馆大多具有企业性质,因此适合公共图书馆尤其是高校图书馆的评估模式应当是基于局域网的数字图书馆——混合图书馆(Hybrid Library)评估模式。对此,韩国首尔教育大学等研究人员根据"德尔非法"(Delphi Method)制订出的混合图书馆评估模式很有借鉴价值,但需要在国内的图书馆评估实践中加以完善,如数字环境下图书馆评估中关于版权保护、读者评估等问题。 相似文献

The 1998 Public Library Outlet Internet Connectivity study (Bertot & McClure, 1998) sponsored by the American Library Association (ALA) and the National Commission on Libraries and Information Science (NCLIS) collected public library outlet Internet connectivity data by outlet metropolitan status, poverty, and region strata. Based on a national survey, the results show that there are disparities in public library outlet Internet connectivity, public access provision, and speed of public access Internet services. Such disparities have implications for future connectivity policy development such as the e-rate, state library-based connectivity programs, and library-initiated connectivity initiatives that this article identifies and explores. Community Access Points (CAPS), in addition to public libraries, may be necessary to reach national goals related to universal service and equality of access to the Internet. 相似文献

This article presents an overview of the methods, findings, and the general implications of the 2007 Public Libraries and the Internet study. This annual study has chronicled public libraries' provision of Internet access to patrons and a range of related issues since the early 1990s. The 2007 study focused on the provision and maintenance of Internet access and services, infrastructure issues, community impacts of the technology, training, library technology funding, and e-government roles of public libraries. This article details these findings, exploring how the 2007 data compare to previous studies. It also considers the implications of these comparisons in terms of the levels of service that libraries are able to provide, the challenges that libraries face in providing these services, and the ways in which communities and governments rely on public libraries to guarantee public Internet access. 相似文献

This article examines historical developments and current trends in Ukrainian library education. It gives a synthetic overview and comparison with US library education, based on a review of the Ukrainian literature, a survey of Library and Information Service (LIS) curricula and interviews with senior figures in Ukrainian LIS education. Ukraine became an independent state only in 1991 after the collapse of the Soviet Union. Previous to independence, Ukraine's LIS education was integrated within the Soviet system. After independence the system evolved slowly, but with the recent Orange Revolution, reform efforts have increased pace. Ukrainian LIS education remains more vocational than in the US, with a two-year non-degree certificate as the most common training, and a four-year bachelor's degree offered by elite institutions. One emerging trend in LIS education stresses the new opportunities for librarians and information professionals opened by Internet technologies. Another is part of a more general shift, inspired by a new Ukrainian higher education law, stressing the country's independent culture and formalizing standards for different degrees. LIS education has now reached a turning point, as reformers grapple with the limited resources, power of inertia, and remnants of Soviet culture in their efforts to meet current challenges and prepare a new generation of information professionals. 相似文献

The Arizona Health Information Network (AZHIN) is a statewide member-driven organization committed to improving access to information for health sciences students and practitioners. Members include several hospitals and hospital systems, an academic health sciences center, and other diverse health care organizations. AZHIN offers its members unlimited Web access to ten well-known health sciences databases. This paper explores the impact that AZHIN has had on its member institutions. A survey asked members to reflect on AZHIN and its possible effects on the visibility of the librarian within the institution, relative dollars spent on AZHIN and range of resources available, Internet connectivity within their institution, access to AZHIN and other Internet resources, teaching, and benefits of collaboration. Results indicated that AZHIN members have access to a wider range of resources than they would otherwise. There are financial savings for some. Internet connectivity and AZHIN membership can provide the librarian with a broadened role and increased visibility. The availability of MEDLINE and other AZHIN resources encouraged some institutions to install Internet connectivity more quickly. Teaching library users has increased. Overall, AZHIN members recognized many benefits of their collaboration. 相似文献

The biblioblogosphere is comprised of the institutional publication of blogs of libraries and the personal, professionally-oriented publication of blogs by librarians. Since introduction of this neologism in 2004, a number of researchers have examined this particular class of bloggers and blogging. However, there is limited investigation into the structure and connectivity of blogs within the biblioblogosphere. This article reports a study of interlinkage patterns within a sample of 1,604 biblioblogs. Findings suggest the biblioblogosphere conforms to the locally dense, globally sparse structure of blog networks established by previous studies of other blog types. The majority of blogs within the sample did not link to any other sampled blog. Those that did tended to cluster according to library type, blog subject, or geographical proximity. About one-third of the interlinked blogs were located within a single, massive component (that is, a networked group of blogs), while the rest were in smaller networks of two or three nodes. Personal biblioblogs, characterized as blogs published by individuals independently of an institution, are more likely to be located within a more densely populated network than institutional blogs. These findings indicate that “personal-professional” bibliobloggers are actively shaping the structure of the library blogosphere, while institutional blogs demonstrate much less overall connectivity. 相似文献

The explosion of availability of information on the Internet requires that libraries evolve into value-added information providers, rather than mere curators of collections. Modern libraries need to stay relevant to a diverse, technologically savvy patron base and to facilitate and add value to the research community, while facing significant resource constraints. To face these challenges, libraries need to embrace digital technologies and library management systems (LMS) in order to work smart and achieve more with less. While LMS systems have been around for decades, libraries can explore the new frontier by embracing open source solutions, like open source software (OSS) library systems, which are free to acquire. They need to collaborate with computer experts and become technologically savvy to harness the full power of OSS solutions to meet the specific needs of the library and patron base. This article provides an overview of the availability, benefits, and drawbacks of various LMS systems and OSS variants, drawing from experiences in the present Indian context. 相似文献

The media have focused a great deal of attention on the Internet in the United States, but what is the status of connectivity outside the United States? The Human Development Index (HDI) created by the United Nations Development Programme (UNDP) ranks 174 countries by human development status, e.g., average life expectancy, GDP per capita, and adult literacy. Since 1991, Larry Landweber, a member of the Internet Society (ISO), has tracked the growth of Internet connectivity worldwide and made this information available via the Internet. Landweber's list is converted into high, medium, and low HDI rankings in order to note the growth of Internet connectivity for 174 countries during the past five years. Additionally, international media reports translated by the Foreign Broadcast Information Service (FBIS) are examined to track discussion of telecommunications or Internet expansion. FBIS citations show substantial coverage of telecommunications development and satellite projects in Asia and the Pacific, and Oceania. It is only within the last two years that the Internet has surfaced in international news reports. FBIS reports also reveal that foreign government officials are confronted with their inability to regulate the Internet. One example involves dissident groups circumventing traditional information channels to broadcast opposing views. 相似文献

Since the 1930s, the Library Bill of Rights has acknowledged the ethical responsibility of librarians to provide access to information in all formats to all people. Librarians are charged with selecting, organizing, and instructing patrons on how to locate and use the resources, and preserving information regardless of format or technology. The information revolution and the pervasive thinking that everything is available on the Web have created new challenges to these traditional professional ethics. Acquiring and providing dependable access to electronic resources require librarians to learn and apply new skills such as negotiating license agreements and understanding evolving technologies. Print publications provide a degree of permanence, but e-information, if it is not properly managed, can be highly transient. Internet services provide large, uncontrolled, unregulated collection of resources. If the very nature of the Internet makes it nearly if not completely impossible to evaluate the content of web-sites, how does the librarian protect the integrity of the information the library provides? Along with traditional ethical conflicts, librarians in the virtual library are faced with new challenges to provide equitable access to usefully organized resources, to address petitions to deselect or filter, to negotiate less-restrictive licensing policies, and to maintain the anonymity of individual users within electronic transactions. 相似文献

This paper provides a broad international overview of e-books in academic libraries. The inconsistent terminology relating to e-books is noted in the first section and a brief history of e-books and some current definitions are given. The stakeholders within the e-book industry are described, with details of some of the services offered. For users and staff in library and information services, e-books can provide a variety of advantages as well as challenges, and these are outlined for those in academic libraries. Findings from various studies on e-books are presented and some of the issues involved in managing e-books in academic libraries are described. Finally an overview is presented of the e-Books Working Group in the United Kingdom. The paper is illustrated with a number of screenshots related to e-books in academic libraries in various parts of the world. 相似文献

Internet diffusion is not homogeneous and depends on many factors. This study uses data from the Canadian Internet Use Survey (CIUS) to explore the extent demographic variables affect Internet use by individuals in Canada. A logistic model confirms that certain factors, educational attainment, and geography in particular influence Internet use in Canada, controlling for age and income. Education maintains a strong, significant impact on Internet use such that the odds of using the Internet are about three times greater for someone who has some post-secondary education than someone who has, at most, a high school education. An urban–rural digital divide persists in Canada with the odds of using the Internet being almost one-and-a-half times greater for someone who lives in an urban area. While language also has a large effect on Internet use, the presence of children in households no longer seems to be a significant factor. This study thus underscores the changing digital environment in Canada and the need for adaptive, flexible policies addressing national connectivity issues and, in particular, broadband Internet availability. 相似文献
