The word 'Bibliometrics' is derived from the two Greek words 'biblio' and 'metrikos' meaning book and measurement. Bibliometrics is the science of measurement relating to books. The word measurement mean the application of mathematical and statistical techniques to find out growth of documents, scattering of literature in various types of documents, publication of documents by an author, impact of document and so on.
Bibliometric studies have been gaining significance in the field of information science in recent years
It has been found that many of the social science and science periodicals are also carrying a large number of articles on Bibliometrics. Bibliometrics involves measurement of several interrelated aspects of writing and publication i.e., quantitative analysis of documents or written material.
Bibliometric methods have been applied in various studies for a century and for using statistical methods for studying subject scattering in publication
The measurement of bibliographic information offers the promise of providing a theory that will resolve many practical problems. It is claimed that author productivity patterns, literature growth rates and related statistical distributions can be used to evaluate authors, assess disciplines and maintain collections.
Definitions of Bibliometrics:
According to Hulme (1923) (1) the purpose of statistical bibliography is to shed light on the process of written communication and of the nature and course of development of a discipline, by means of counting and analyzing its various facts of written communication.
Rising's (1962) (2) definition was one of the most classical definitions. He defined bibliometrics 'as the assembling and interpretation of statistics relating to books and periodicals to demonstrate historical movements to determine national and universal research, use of books and journals'.
Pritchard (1969) (3) defined the term Bibliometrics thus 'Bibliometrics is the application of the mathematical methods to books and other media of communication'.
International Journal of Library and Information Studies:
International Journal of Library and Information Studies (ISSN: 2231-4911) is an international online peer reviewed and indexed journal. IJLIS is initiated by the founders of 'PEARL--A journal of Library and Information Science'. This will consider any original contribution that enhance or illuminates Library and Information Science or Practice, or that educates or entertains the journal's readers. IJLIS is a Quarterly publication.
The present investigation is concerned with the analysis of citations cited in International Journal of Library and Information Studies. Total 371 citations are appended from 8 issues of publication of International Journal of Library and Information Studies. These citations are utilized for the present investigation.
The main objectives of the present paper are:
* To know the various sources of information consulted by the authors in International Journal of Library and Information Studies,
* To test the authorship pattern in published articles in International Journal of Library and Information Studies,
* To know the nature of authorship pattern in cited journals in nature of authorship pattern in the International Journal of Library and Information Studies,
* To examine the core journals of International Journal of Library and Information Studies,
* To study the distribution of citations by subject International Journal of Library and Information Studies,
* To study the Geographical distribution of citations in International Journal of Library and Information Studies and
* To know the language wise distribution of journal citations in International Journal of Library and Information Studies.
The first review of bibliometric Empirical Laws was written by Fairthorne (1969) (4). The second important one was published by Hjerppe (1980) (5) which contains more than 200 items on bibliometrics. The most comprehensive historical review was published by Hertzel (1987) (6) in Encyclopedia of Library and Information Science'. Sangam (1993) (7) examined their paper entitled 'study of age distribution of journal citations in the American Economic Review' and they found obsolescence rate, bibliographic form-wise distribution of citations, and country-wise distribution of citations etc. Pichappan and Sangaraamachiyar (1996) (8) have suggested that it is necessary to include eponyms, anonyms and footnotes in age studies.
Bandopadhyay (2001) (9) studied authorship patterns by analyzing the citations appended to 92 doctoral dissertations submitted to University of Burdwan for the period 1981-1990. The results revealed that the average number of authors per paper in Physics was 2.25, followed by Mechanical engineering (1.48%), Mathematics (1.44%), Philosophy (1.15%) and Political Science (1.05%).
Padmamala Iyyangari (2002) (10) studied the authorship and collaborative research. Single authorship was found to be the highest in all the 12 issues of (LISA) Library and Information Science Abstracts. Kannappanwar et al., (2004) (11) made a study which highlighted the authorship trend in collaborative research in Chemistry in India during the period 1996- 2000. Their study reveals that the team research was preferred compared to solo research.
Roy (2004) (12) analysed institutional collaboration in Indian Library and Information Science journals. He analysed 1637 research papers in 10 Indian Library and Information Science journals during the period 1991-2000. The results indicate that the institutional collaboration in Indian Library and Information Science field is not high. Seventy two percent of articles were contributed by single institutions. Kunwar Singh et al (2011) (13) analyzed the research publications for a period of tenyears from 1992-2002 to assess the trends in the publication patterns in DESIDOC Bulletin of Information Technology by library and information professionals.
