Journals are no doubt the most preferred source of information in any field of research due to the nascent information that they carry and faster delivery of research output. But the increasing subscription rates and budget constraints forcing libraries to select and subscribe only the popular journals from the huge number of journals published in different subject fields. Bibliometrics and citation analysis have emerged as the important tools for selection of popular journals in any area of research or subject. As Zafrunnisha (2012) explains, bibliometric techniques are being used for a variety of purposes such as determination of various scientific indicators, evaluation of scientific output, selection of journals for libraries and even forecasting the potential of a particular field. Anyi et al (2009) are of the opinion that bibliometric analysis of single journal creates the portrait of that journal and indicates the quality, maturity and productivity of the journal in any field, in a country or region. It also informs us about the research orientation that it supports to disseminate and its influence on author's choice as a channel to communicate or retrieve information for their research needs. Taking these advantages of presenting bibliometric portrait of journals, SRELS Journal of Information Management is selected for this study. SRELS Journal of Information Management has emerged as one of the highly regarded journal in the field of library and information science in India. In this study an attempt is made to examine the characteristics and present the bibliometric portrait of SRELS Journal of Information Management.
Sarada Ranganathan Endowment for Library Science has been publishing the quarterly journal 'Library Science with a slant to Documentation' since 1964. It was founded by Dr. S. R. Ranganathan. The title of the journal was changed to "Library Science with a slant to Documentation and Information Studies" from Vol.25 in 1988 and to "SRELS Journal of Information Management" from Vol.37 (2000). The journal has been publishing scholarly articles and articles of practical use in the fields of library and information science and services. SRELS Journal of Information Management is published bi-monthly (6 issues per year) since from 2010. Journal has well defined guidelines for authors to submit articles and is peer reviewed by the board of editors. Beginning 2014, the journal is published by Informatics Publishing Limited, Bangalore. From 2015 onwards, manuscripts have to be submitted online and the entire review process will be electronic.
Objectives of the Study:
The objectives of the study are as follows:
* To map year-wise distribution of articles
* To find the average length of articles
* To examine the authorship pattern of the contributions
* To study author productivity
* To study the range and percentage of references per article
* To study different types of resources used and number of citations appended
* To study different collaboration measures
* To identify and prepare ranked list of authors and journals
* To identify and prepare geographical list of contributions and State-wise list of Indian contributions
* To study Lotka's law of scientific productivity
* To study Bradford's law of scattering
The data required for the study was collected from both print and electronic version of the journal for the period 2004-2013. The references appended to each article were carefully scanned and tabulated in respective tables using Microsoft Excel. The details regarding number of articles published, author names and affiliations are recorded for each article. Citation analysis technique and required bibliometric measures are applied.
Analysis of Data:
Following section discusses the analysis of the data collected and presented under different table headings as per the objectives of the study.
5.1 Distribution of Contributions:
Table-1 depicts the number of articles published during the period 2004-2013. In all, 499 articles are published during the period 2004-2013. The study shows that the highest number of 70 papers are published in the year 2013 followed by 65 papers in the year 2012 and 63 papers in the year 2011. The lowest number of 35 papers published in the 2006 followed by 36 papers in the year 2005. The journal on an average published 10 papers per issue. The number of papers published each year is not consistent and there is sudden rise in the number of papers in the years 2010-2013. This could be because of the fact that the journal's frequency is changed from Quarterly to Bi-Monthly from 2010.
5.2 Length of Articles:
The length of the articles is shown in Table-2 where it is found that 253 (50.70%) articles had page length in the range of 6-10 pages followed by 130 (26.10%) in the page range of 10-15 pages. There are 4 (0.80%) articles having more than or equal to 31 pages. An article published in the year 2013 has the maximum page length of 42 pages. zzz 5.3 Authorship Pattern:
The authorship pattern is analysed to determine the percentage of single and multiple authors. From Table-3, it is revealed that single and two-authored contributions have dominated this journal. Single authored contributions accounts for 173 (34.70%), two authors are 258 (51.70%), three authors 54 (10.82%), four authors 9 (1.80%) and more than four authored papers are 5 (1.00%). In all, there are 326 (65.30%) multi- authored contributions during the study period.
5.4 Author Productivity:
Yoshikane et al (2009) in their paper published in Scientometrics journal have given a formula to calculate Average Author Per Paper (AAPP) and Productivity Per Author. The formula is mathematically represented as below:
Average Author Per Paper = No. of Authors/No. of Papers
Productivity Per Author = No. of Papers/No. of Authors
Table-4 depicts the data pertaining to author productivity and average author per paper. It is revealed from Table-4 that the average authors per article is 1.83 for 499 articles published during the period 2004-2013. It is also clear from above Table-4 that for the years 2008 & 2013 equal average number of authors per article is recorded i.e., 1.82.
The average productivity per author is 0.55 and ranges between 0.49-0.61 for the period 2004-2013. The years 2008 and 2013 have recorded equal productivity per author i.e., 0.55 and it is highest for the year 2004.
5.5 Lotka's Law of Scientific Productivity:
Lotka's Inverse Square Law of Scientific Productivity describes the frequency of publication by authors in any given field/subject. It states that the number of authors producing n contributions is approximately equal to 1/n2 of the number of authors that produce only one contribution. For example if Sixty authors out of One Hundred in a subject area produce only one paper, then Fifteen out of One Hundred will produce two papers, Seven out of One Hundred three papers and so on. Lotka's Law is mathematically expressed as:
[Y.sub.x] = C/[X.sup.n]
Where, Y is the number of authors credited with X (1, 2, 3, 4......) papers
C is the number of authors contributing one paper And n is rate
[X.sup.n] * [Y.sub.x] = C (Where X = 1) i.e., 1 * 397 = C (C = 397, number of authors contributing one paper) When X=2 [2.sup.n] x 82 = C (C = 397) [2.sup.n] = 397/82 = 4.84 (by applying log) n...
