Abstract

Digital libraries (DLs) have evolved, and developments in information technology have changed the concept of the library from one of print and paper media to digital media. The success of a DL depends upon the computers, communication skills, and knowledge of library professionals in connection with modern technology. In the present scenario, we stand at a transition from the traditional library to a global DL. The technology-based idea is to provide universal access to digital content available only in a DL environment.

Today the emergence of digital technology and computer networks has provided a means whereby information can be stored, retrieved, disseminated and duplicated in a fast and efficient manner. On a global level, DLs have made considerable advances both in technology and its application. India still has far to go if the nation is to benefit from this movement. Only sporadic and partial attempts have been made towards DL initiatives in India.

The basic objective of DL initiatives in India has been to preserve the art, culture and heritage of this country. All projects aimed at creating DLs concentrate only on specialized collections. The DL initiative in India is still at a nascent or embryonic stage. But with the initiative like DL policy, it can also be said that the nation is serious about DL implementation.  相似文献

Digital libraries (DLs) are complex information systems which can present changes in their structure, content, and services. These complexities and dynamics make system maintenance a non-trivial task, since it requires periodical evaluation of the different DL components. Generally, these evaluations are customized per system and are performed only when problems occur and administrator intervention is required. This work aims to change the situation. We present 5SQual, a tool which provides ways to perform automatic and configurable evaluations of some of the most important DL components, among them, digital objects, metadata, and services. The tool implements diverse numeric indicators that are associated with eight quality dimensions described in the 5S quality model. Its generic architecture was developed to be applicable to various DLs and scenarios. In sum, the main contributions of this work include: (i) the design and implementation of 5SQual, a tool that validates a theoretical DL quality model; (ii) the demonstration of the applicability of the tool in several usage scenarios; and (iii) the evaluation (with usability specialists) of its graphical interface specially designed to guide the configuration of 5SQual evaluations. We also present the results of interviews conducted with administrators of real DLs regarding their expectations and opinions about 5SQual.  相似文献

Today libraries are at a transition phase where twin processes of paper-based environment and changing information-seeking patterns in the electronic/digital environment go hand-in-hand. Hence, all components of the information chain are in a state of flux. The rapid growth in computer and communication technologies have greatly benefited the advanced countries, while the developing countries have not adequately reaped the benefits of such facilities to the desired extent. The application of information technology (IT) in India started on a very modest scale. During the past decade or so several Indian libraries have initiated activities to create, acquire, and provide access to electronic resources. The establishment of networks has had a great impact on libraries and information centers (LICs) in the country, and have further buttressed the IT applications in the LICs to a certain extent. The emergence of the Internet, especially the World Wide Web (www), added a new dimension to information creation and delivery, which also globally triggered digitization programs. Buying access or acquiring digital resources started taking root. The digitization of records (document management) crept in, which attracted librarians and people from other professional backgrounds into records management. This was followed by content management, (currently a popular phrase in this part of the world), also known as digitization. The digitization of documents is now becoming a major activity in libraries and archives. The Indian National Science Academy (INSA) is a premier scientific body engaged in the dissemination of information to the scientific community at large, publishing and promoting scientific endeavors, besides having other multifaceted human welfare-oriented activities. The growing acceptance of digital media has resulted in libraries buying and providing access to Internet resources, acquiring CD-ROM-based data-sets, and providing services for stand alone or networked CD-ROM environments, and digitizing documents. The Academy library facilitates all three. The Academy has initiated several digitization initiatives for content development and management by way of the scanning of publications, image management, and conversion from digital documents to web-enabled resources. The Academy has adopted a three-pronged approach of providing access to digital resources, and acquiring and creating digital resources, for which INSA suitably augments with IT infrastructures and takes initiatives to provide links to requisite data sets for the benefit of its users. INSA developed and provided IT facilities at a modest scale to its users at a time when only a limited few had developed such facilities in the country. The facilities developed at INSA augur well with the initiation of pilot and sponsored projects pertaining to digitization of records and making provision for creating digital resource bases, thereby contributing to the national digital repository on the one hand and providing access and visibility to national resources on the other. The article dwells upon various elements that have contributed to providing services in the changing information seeking patterns of users in the electronic environment, and the building of digital resource bases, while facilitating others to get involved in digital content creation activities. It is hoped that such endeavors shall help in the building up of a national digital knowledge resource base for the country, and INSA would in the process act as a facilitator.  相似文献

Digital library (DL) evaluation is essential to the success and enhancement of DLs. However, there is a lack of research on the assessment of comprehensive evaluation criteria across multiple dimensions of DLs. In particular, limited research is available on criteria prioritization to determine which criteria are perceived important by different stakeholders. This study was conducted to compare similarities and differences in perceptions of the importance of different DL evaluation criteria by heterogeneous stakeholders in academic settings. Ninety subjects were recruited with 30 from each of the group representing DL scholars, DL librarians, and DL users. Subjects were instructed to fill in an in-depth survey consisting of 10 evaluation dimensions with 94 criteria. ANOVA and t-test were applied to examine the similarities and differences among the three groups. This study reveals consensus and divergence in perceptions of criteria importance among the three groups, and indicates an inherent tension among the stakeholders. Moreover, the differences identify gaps not only between user expectations and the DL practice but also between what's desirable and what's possible in the academic environment. The findings provide a comprehensive list of criteria to guide practical evaluation of DLs, and contribute to the narrowing of the identified gaps.  相似文献

This article addresses the different institutional and cultural contexts which must be considered when implementing E-Government in sub-Saharan Africa. Although E-Government is a global phenomenon, simply transferring ICT solutions and related organizational concepts from developed to developing countries seems inappropriate. E-Government undoubtedly has the potential to reduce administrative and development problems. However, it is obvious that compared to developed countries, additional effort is necessary when implementing E-Government in developing countries. More than in developed countries, the different initial institutional, cultural, and wider administrative contexts must be considered to avoid unintended effects. It is oversimplifying the issue to merely state that E-Government projects fail in Africa and other developing regions. Although E-Government in African countries lags far behind developed countries, this should be considered more as a state failure or lack of capacity in general. In particular, the different administrative contexts and rationalities must be taken into an account when implementing E-Government projects and strategies. Therefore, especially for African countries, a context-oriented approach seems to be a more promising route to the successful implementation of E-Government. The results of this approach may not seem ambitious from a western perspective, but could contribute to the solution of real-life and development problems in African societies.  相似文献

The article discusses how the Indian agricultural libraries have transformed through various innovative projects in the recent past. Libraries in the National Agricultural Research and Education network have connected and collaborated to deliver information resources as per the changing needs of the academic community. The author describes the initiatives made through projects for upgrading libraries and moving them to virtual environment and digital platforms like IDEAL and central digital repositories like Krishikosh. Collaborative projects like CeRA–consortiums and union catalogue–AgriCat developed on Koha have made a breakthrough in transformation. Sustainable development of digital platforms is important; how the various platforms have been sustained and continued is interesting. Some of the challenges and constraints in institutional repositories, open access, and digital accessibility of e-resources for new, developing universities and bridging the digital divide are also addressed. Through describing these transformations, the author concludes that attention of academicians and librarians is required to facilitate and popularize use of e-resources and bring greater dependency on e-text in light of the changing technological scenario.  相似文献

Mass Digitization of Books   总被引:1,自引:1,他引:1  
Mass digitization of the bound volumes that we generally call “books” has begun, and, thanks to the interest in Google and all that it does, it is getting widespread media attention. The Open Content Alliance (OCA), a library initiative formed after Google announced its library book digitization project, has brought library digitization projects into the public eye, even though libraries were experimenting with digitization for at least a decade. What is different today from some earlier digitization of books is not just the scale of these new initiatives, but the quality of “mass.”  相似文献
