The emergence of the system of open and distance education is an inevitable development in the evolution of education internationally. With the increasing popularity of distance education, focus has turned to the role of libraries in the distance learning process. The library is an important tool for individuals' intellectual development. Academic libraries contain resources for research, teaching, and learning. This paper examines the efforts being made by Nigerian university libraries to fulfill the information needs of distance education students in their respective institutions. This study was carried out in four Nigerian universities running distance education programs. The questionnaire method was used for data collection. The respondents used in this study were randomly selected from the distance learning (DL) students of the universities under study. It was discovered that DL students were not adequately catered for as far as the use of library resources is concerned. A student could graduate without having used libraries. The study recommends that adequate planning and financing should be made for DL students to be able to make use of the libraries and information resources. It adds that this would enhance their critical thinking and also enhance their degree of exposure to existing knowledge. 相似文献

A two-part questionnaire was designed to elicit information on use of print and electronic resources by agricultural science students in Nigerian universities. 912 respondents from faculties of agriculture in three Nigerian universities completed the questionnaires. The results revealed that agricultural science students most prefer to use textbooks (42.1%) among print materials, while The Essential Electronic Agricultural Library (TEEAL) is the most preferred among electronic resources available in their libraries (52.2%). Major problems faced by the agricultural science students include inadequate access to full Internet connectivity and lack of skills on their part to use available electronic databases properly. The study recommends restructuring library collections by increasing the number of agricultural textbooks and databases to meet the information use and retrieval needs of agricultural science students. Other recommendations include establishing Internet-ready computer centers to complement teaching, learning, and research in the library. 相似文献

This paper discusses Nigerian university library buildings from 1948, when the first university institution was established, up to 1998. Through the use of a questionnaire, study visits to 12 of the 31 university libraries, interviews with library staff and review of the literature, it was found that all Nigerian university libraries started from temporary sites. While all five first generation universities had their first permanent library buildings erected within the first decade of their establishment, only five of the eight second generation universities have moved into their permanent library buildings after over 25 years of existence. Of the 15 third generation universities established in the 1980s, only five have erected and occupied their permanent buildings. Library buildings of the first generation universities were found to be very standard and grand in design while the same cannot be said of most of their second and third generation counterparts. For libraries with permanent structures, the designs were mostly modular. The paper recommends that library buildings be given priority in universities' physical development plans and that realistic library building standards be formulated with the co-operation of the National Universities Commission, the Nigerian Library Association and the Committee of University Librarians of Nigerian Universities (CULNU). 相似文献

Digital libraries aim at unhindered access to content over computer and communication networks, and digitization may be taken as a visible proposition to enhance the shelf life of non-digital content by preservation apart from the virtue of increased and easy access, thereby furthering usage. As a fresh, lively and dynamic area with a lot of enthusiasm and activity by researchers from different disciplines, institutions and countries, digital libraries are viewed in different perspectives and the single most development that has brought about sweeping changes in the library and information discipline currently in the developed world is that of digital libraries. Advancements in computer and information technology with breakthroughs in memory technology has not only reduced the cost of infrastructure required for hosting digital libraries, but the demonstrated success of a wide variety of projects in USA and Europe also endorsed the chances of their survival even in a developing country. Though the professionals and libraries in developing countries are also experiencing the virtues of Internet, and electronic information highways, many of these libraries have not gone much farther than the computerization of in-house operations, availing databases in electronic media such as CD-ROMs, and web access of subscribed journals and various free resources. Digital library development should be taken up as an additional task to populate the web sites with valuable in-house content like the research reports, publications of in-house researchers, and so on. Digital library projects and developments in the country are so many, though a large number of them are only at an aggressively enthusiastic preliminary stage. In a country such as India so rich in content of indigenous research and development in disciplines varied from science and technology to social science, humanities and spirituality, there is tremendous need for hosting full fledged digital libraries by appropriately tagging the content with affordable information technology. However, what is lacking, especially in developing countries, is a coordinated collaborative approach to bring in institutions and identifying content valuable for digitization with sufficient monetary and infrastructure support. The digital library development in the country needs a two-pronged strategy (i) to digitize local content, and (ii) to devise options for accessing external resources. Channels for internal content include journals and serials for research, conference proceedings, theses and dissertations and preprints, research and status reports, textbooks and learning materials, government publications, spiritual/heritage sources, tourism information, traditional knowledge, etc. As far as external resources are concerned, there are electronic options from publishers and information provides such as, online access through Web of subscribed journals, CDs and floppies containing supplementary material of printed books, bibliographic/full-text databases, which can be hosted on library servers or intranet along with local content. The problems for digital library development are manifold in India such as lack of interest, non-availability of computer and IT infrastructure for library activities, copyright problems, ensuring secure access, properly selecting content from the mass available, internet bandwidth, absence of sufficient financial support, over concentration of professional time on administrative routines, acute shortage over concentration of professional time on administrative routines, acute shortage of competent manpower, etc. The software boom engulfing the country, as a result of the big leap in computer penetration, sudden rise in proficient manpower, and sizable improvement in communication infrastructure should also be treated as an asset and taken advantage of by authorities and information professionals to create and maintain digital information facilities to usher in the new information age. 相似文献

By means of a mailed questionnaire, a study was undertaken to assess the collection development resources and procedures of public libraries in a developing country, Nigeria. Usable responses were received from nine of the nineteen public (state) library services in the country. The results show that Nigerian public libraries receive grossly inadequate funds, especially for acquisition of library materials. Consequently the libraries' collections are small. There is no uniform pattern of allocating staff to the acquisitions departments, which are over-staffed in relation to their workloads. It was found also that slightly differing acquisitions procedures are adopted by the various public libraries. 相似文献

Computerization of library services is intended to modernize the entire library system in Nigeria as in the industrialized countries, and to ensure accuracy, efficiency, effective information management, reliable user services, enhanced interlibrary co-operation and library prestige. By 1985, only the library of the International Institute for Tropical Agriculture (IITA), Ibadan, had succeeded in automating its library services. Other libraries are mostly at the trial stage. University and research libraries and the National Library of Nigeria are leading the race to computerize their services. Lack of co-operation between libraries is an obstacle to library automation in Nigeria. Some librarians are not sure whether computerized library services would thrive owing to problems of poor funding, inadequate physical and environmental facilities such as low grade buildings, unreliable power supply and the scanty amount of information holdings in most of our libraries. Staff computer training, standby power generating plants, competent personnel, computer technicians and support for computer acquisition and hardware maintenance are major factors to consider before any Nigerian library decides to automate its services. In future, use of natural language by computers will make computers more user friendly. Installation of mini- or microcomputers, with powerful information storage capacity, rather than main frames are recommended for small Nigerian libraries with fewer than 20000 book titles, but which wish to automate their services. 相似文献

Information inequity is a central concern of the digital age. Many recognize the role of public libraries in bridging such inequities. Unfortunately, however, public libraries are often limited by the funding available to them. This study used a geographic information system (GIS), inequality measures, and multiple regressions to analyze statistics from the Public Libraries Survey (PLS) collected by the National Center for Education Statistics (NCES) and from census tract data. It evaluated the levels of public library funding and services and tested how these resources vary with neighborhood income and urbanization levels. This is one of the few nationwide multivariate studies of neighborhood-level variations. The study revealed significant funding and service variations across the nation's 9000 library systems. Distributions of digital materials, full-time staff with a master's degree in library and information science, and library programs were especially disparate. Library systems in lower-income or rural neighborhoods were relatively less funded and offered fewer information resources. Interestingly, the only variable that was not significantly associated with neighborhood income was the number of public Internet terminals. This suggests that recent funding and research efforts may have made a difference. Similar funding efforts are encouraged for other types of library resources such as staff education and training. In light of the prevalent disparities in resource levels across neighborhoods, the study calls for a fundamental evaluation of the funding mechanisms for libraries. Also, information behavior research should investigate how this structural information inequity affects individuals’ information use decisions. 相似文献

Web site usage statistics are a widely used tool for Web site development, but libraries are still learning how to use them successfully. This case study summarizes how Morris Library at Southern Illinois University Carbondale implemented Google Analytics on its Web site and used the reports to inform a site redesign. As the main campus library at a research university with about 20,000 undergraduate and graduate students, the library included resources from multiple library departments on a single site. In planning the redesign, Morris Library's Virtual Library Group combined usage reports with information from other sources, such as usability tests and user comments. The Virtual Library Group faced barriers to interpreting and applying the usage statistics in the site redesign, including some that were specific to the library's implementation of the Google Analytics tool and some limitations inherent with Web usage statistics in general. Some key barriers in applying the usage statistics to a redesign included sifting through data that did not have implications for the site redesign, interpreting the implications of usage numbers for the site redesign, and balancing competing interests within the library. Nevertheless, the usage statistics enabled the Virtual Library Group to make better decisions by providing a source of factual information about the site's use rather than relying on staff members’ opinions and conjectures. 相似文献

The purpose of this study was to identify the challenges students faced in accessing the information from academic libraries during COVID and factors that contributed to stress among students during the pandemic. Another purpose of the study was to know the expectations of the students regarding libraries' services and library professionals' competencies in the post-COVID era. A quantitative research approach and survey method was employed to conduct this study. The population of the study was students of public and private sector universities in Pakistan. Statistical Packages for Social Sciences (SPSS) was used to analyze the collected data. Results revealed that lack of digital resources (limited access to the internet and digital devices such as smartphones) and limited information skills found the highest mean score (3.92 and 3.90 respectively) regarding contributing to stress among the students. Similarly, findings confirmed that lack of access to printed material and printers, scanners, recorders, and websites with limited guidelines were the major challenges students faced while accessing the information from academic libraries during the period of a pandemic. Students agreed and expected remote access to information sources, availability of more electronic content, presence of online tutorials regarding the use of information sources and access to institutional repositories from libraries after the COVID era. Respondents also agreed that post-COVID librarians should be good information managers, communicators, problem solvers and internet librarians. The study also shares the implications for practitioners and polisymakers and future research directions for academics and researchers. 相似文献
