2 AGENDA Digital Library? Why Digital Library? Development of Digital Libraries & Need of the Study? Significance of Literature Objectives of the Study Materials and Methods Results and Discussion Findings and Conclusion

3 DIGITAL LIBRARY Digital Library is where the past meets the present and creates the future Dr. APJ Abdul Kalam ICDL-2004 A digital library is a library in which collections are stored in digital formats and accessible electronically. The digital contents may be stored locally or hosted on clouds or accessed remotely via computer networks Different terms like virtual library, electronic library, and library without walls are in use to represent digital library Users of library have also changed, they prefer to visit the library online and not physically Librarians may discover that Libraries without walls are actually only libraries with new walls technologically bounded, legally restricted and administratively hamstrung The real goal of the digital library remains the same as that of traditional library that is to collect, preserve information resources, organize and make them accessible to the users

4 WHY DIGITAL LIBRARY? Digital library technology is becoming an essential enabler of library services. The digital library network within the users community saves a lot of access time and energy of both the users and the library or information personnel. No physical boundary Round the clock availability Multiple access Preservation and conservation Solves space problem Networking Optimal use of ICT environment Structured approach Ability to deal with large data sets On-line learning environment Wider range of materials Access to latest information Faster information retrieval Lower maintenance and cost effective, etc.

5 DEVELOPMENTS OF DIGITAL LIBRARIES vis-à-vis NEED OF THE STUDY The new environment is really challenging one for the librarians and any one who has access to the network of digital libraries can be a publisher by merely posting messages to an online discussion group or by other means. A virtual environment is really open for all With continued improvements in book handling and presentation technologies such as optical character recognition and ebooks, and development of alternative depositories and business models, digital libraries are rapidly growing in popularity as demonstrated by Google, Yahoo!, and MSN's efforts Just as libraries have ventured into audio and video collections, so have digital libraries such as the Internet Archive This is leading to lot of published literature on Digital Libraries and Need to have bibliographic control of the Literature

6 SIGNIFICANCE OF LITERATURE Literature provides knowledge Literature builds experience Literature provides base for further developments and Research Literature secure historical developments of a subject Literature develops thinking skills

7 OBJECTIVES The main objective of this study is to quantify the trend of world literature on digital library and to make the scientometric assessment of the status of research by way of analyzing the following features of publications of the study period ( ): Annual output of publications on digital library Geographical distribution of publications Authorship pattern and Prolific authors Institutional distribution Form-wise distribution Language-wise distribution International collaboration Subject dispersion Citation pattern Cited references pattern, etc.

29 CONCLUSION USA is the major contributor with 669 papers to its credit on the subject. Growth of the literature on digital library showed discouraging trend during Only 20 countries have contributed 86.84% of publications. Top ten ranked authors contributed 20.14% publications on digital library. Most productive institution was University of California by contributing 49 (2.83%) publications followed by the University of London with 36 (2.08%). Proceeding papers amounted to 59.78% of the literature followed by journal articles with 32.03% publications. The most preferred source was the journal Lecture Notes in Computer Science with 362 (20.89%) papers followed by Research and Advanced Technology for Digital Libraries with 155 (8.94%) publications. English language dominated with 98.50% publications and other languages like, Chinese, Russian, Japanese and Spanish did also find place in publications on digital library.

30 CONCLUSION In UK, foreign collaborations were reported in 24.66% publications followed by New Zealand with 21.57% collaborations in its publications and India collaborated in its 10.26% publications. In categorization of publications, computer science was at first position with 81.77% publications. Publications in the form of journal articles received more citations than other types of publications and publications in the form of proceeding papers received fewer citations. The study provides a base for researchers, institutions and policy makers to initiate new research projects or studies in the area. It also makes researchers aware regarding the growth of quality research literature of their interest in the subject. It helps in identifying highly productive countries and researchers in the area. The study provides details of institutions and researchers working in specific subject areas in the field of digital library. The study may help policy makers to make effective policies related to digital libraries.
