Keywords: Bibliometrics, DESIDOC, DJLIT, Authorship pattern, Reference pattern, Relative
growth rate
Introduction
Bibliometrics is the application of statistical methods and techniques to the analysis of a
discipline's published literature. Alan Pritchard coined the word "bibliometrics" in a paper titled
"Statistical Bibliography or Bibliometrics?" published in 1969. He explained the term as "the
implementation of mathematical and statistical analysis to books as well as other forms of
communication." A bibliometric analysis is a specific quantitative tool for measuring
bibliographies to assess and evaluate a subject's progression. At this time, bibliometrics is
becoming more versatile and interdisciplinary. These bibliometric assessments focus on the
authorship pattern, article distribution, geographic distribution, pattern of contributions and
contributors, major productive authors, degree of collaboration, and other important bibliometric
patterns. Bibliometric studies aimed to evaluate global research output and use bibliometric
approaches to explain the evolution of a scientific field. Bibliometrics is now one of the
interdisciplinary research areas, with implications in almost every research field.
Research publications are considered the primary medium for socializing research outcomes and
original concepts in a domain. They also aid in the comprehensive study of a topic and serve as
sources of literature progression in any area of research. These publications are one of the most
significant products of investigations since it communicates the research findings to the rest of
the globe in journal papers. DJLIT is open access, bi-monthly peer-reviewed journal. It was
established in 1980 and aims to introduce current developments in information technology to
LIS. The journal is seeking original research papers in the area of information technology. It
aims to bring up-to-date information technology advances as they relate to Library and
Information Science.
Objectives
The study was focused on the following objectives in the contexts of bibliometric factors
reported in DJLIT between 2011 and 2020. The study was conducted to analyze the trends in
published papers.
• To assess the distribution of articles and the annual growth rate of publication in the
DJLIT journal between 2011 and 2020.
• Assess the relative growth rate (RGR) and the time to doubling (DT).
• To examine the volume and issue-wise authorship pattern of articles.
• To ascertain the productivity of the author and degree of collaboration (DC).
• To calculate the pattern of reference distribution by calculating the average number of
references per article.
• To find out the highest number of contributions made by the top ten most prolific authors,
as well as their ranking on total publications and citation rank
Literature review
Bansal (2013) reports that 391 papers were published in the DESIDOC Journal of Library &
Information Technology during the study period (2001-2012). Over two time spans, 2001-2006
and 2007-2012, the study examines the pattern of authorship, subject's coverage, citation analysis
of the references, geographic distribution reported in the DESIDOC journal. In 2012, 65
cumulative papers were written. Joint collaborators contribute 61.4 percent, with India
accounting for the vast majority of outputs. During the study period, Dr. BM Gupta published
most papers (26) in the journal. The majority of papers (65%) are between 6 and 10 pages long.
Pandita (2014) investigated a bibliometric analysis on the DESIDOC Journal of Library and
Information Technology (DJLIT) from 2003 to 2012, in which 366 articles were published. The
research discovered that the journal has 147 articles with two authors, followed by 139 articles.
During the investigation period, the journal published an average of 6.20 articles per issue, with a
total of 5063 references, resulting in 13.83 references per article, and discovered that the highest
citation rate was found in Vol. 31.
Singh and Bebi (2014) conducted a bibliometric analysis on Library Herald from the specified
period (2003-2012). The journal published 234 papers during the study period, with 114
(48.72%) being single-authored and 90 (38.50%) being double-authored. Nosrat Riahinia was the
most active author, contributing 16 articles over the study period. The majority of the publication
came from India (81.6%).
Brahma and Verma (2018) reviewed the Malaysian Journal of Library and Information Science
from 2007 to 2016, discovering that the year 2011 had the most articles published (28), including
an average of 9.33 publications per issue. The study revealed that 40.09% of total articles were
published with the contributions of two authors, following three authors (25.24%). Malaysia was
ranked first with 31.17% contribution in total published articles, and India was ranked second
with 8.50% contribution, and the DC was 0.76, and each article had an average of 31.11
references.
Haque et al. (2019) conducted a bibliometric study of the E-Journal of Library Philosophy and
Practice from 2014 to 2018. According to the study, 1046 articles were published, with 2018
having the most (421) papers published. The survey results also revealed that two author
patterning was the most preferred (39.67%) type of author patterning among published articles.
The average percentage of paper collaboration between 2014 and 2018 was 0.71. 2223 authors
contributed 1046 papers, and per author, the average number of publications was 0.47.
Methodology
The research focused on bibliometric analysis, which intends to review the specifics of the
published articles in the journal (DJLIT) over ten years (2011 -2020). A total of 588 papers were
collected from 60 issues of 10 volumes listed on the website. Data collected from the website
(https://publications.drdo.gov.in/ojs/index.php/djlit) were retrieved, checked, and analyzed as per
the study's objectives. MS Excel was used for analyzing the accumulated data, and they were
portrayed in tables and figures.

Relative Growth Rate (RGR) and Double Time
The publication growth rate was calculated using Mahapatra's RGR and Dt model, which he
created in 1985. 1985 (Mahapatra). The following formula is used to measure the relative growth
rate and doubling time =
Where,
• RGR denotes the growth rate over a given interval span,
• W1 denotes the loge of the interval (natural log of the initial number of contributions)
• W2 = Loge (natural log of the final number of contributions)
• T1 is the initial time unit.
• T2 denotes the final time unit.
Where,
• R= Growth rate
Table III and Figure II display the relative growth rate and doubling time of articles published in
DJLIT from 2011 to 2020. The relative growth rate has been found to have decreased from 0.79
to 0.1. The average relative growth rate for the first five years of 2011-2015 is 0.33, while the
mean growth rate for the remaining five years is declined to 0.13. It demonstrates that there is a
significant gap between the first and second blocks.
The corresponding doubling time (Dt) for different years is progressively increasing from 0.88 to
6.93 from 2011 to 2020. The average frequency of doubling time for the first five years is 1.74
and the remaining five years is 5.55. The average mean relative growth rate of publications is
0.23. The analysis shows that the average mean growth of the article has shown a decreasing
trend during the observation period, and the doubling time seems to have resulted in an
increasing trend from later to initial stages.

Degree of Author Collaboration in DJLIT
Table VI and Figure IV displays the ratio of collaborative papers to total papers throughout the
specified timeframe using the formula proposed by Subramanyam (1983), which is-
DC= / +
Where , DC = Degree of Collaboration,
Nm = Multiple Authored Publications
Ns = Single Authored Publications
DC= 387/387+201=0.65
The result demonstrates that within ten years, the average degree of author collaboration is 0.65.
The table illustrates that the value of DC was at its highest in 2018 at 0.75 and lowest at 0.53 in
2013.

Findings
• 588 papers were published during the ten years, with the maximum number of
publications 11.90% in 2012, followed by 11.04% publications in 2013and in 2014,
10.71% articles were published in Vol. 34.
• The average mean for the relative growth rate of publications is .23 and for Dt is 3.4 over
the study period. The average mean growth of the article has shown a decreasing trend,
and the doubling time seems to have resulted in an increasing trend from later to initial
stages.
• The authors' average frequency per paper was 1.94, and the average number of
publications per author is 0.51 for 588 publications published between 2011 and 2020.
• The Authorship Pattern of articles for ten years revealed that two authors contributed the
most articles for ten years, with 265 (45.06%), single-author with 201 (34.18%), and three
authors with 87(14.79 %). Furthermore, it was discovered that only 35 (5.95 percent) of
the publications had more than three authors.
• Within ten years (2011-2020), the average degree of author collaboration is 0.65. The
table illustrates that the value of DC was at its highest in 2018 at 0.75 and lowest at 0.53 in
2013
• B.M. Gupta contributed the most articles (19), followed by Dhawan SM and Ramaiah
C.K, who contributed 14 papers. Garg K.C. has obtained the most ACPP 3.27 in seven
articles.
• Based on a reference distribution pattern, 10743 references were outlined from 588
publications, including an average of 18.27 references for each article. Vol. 39 has the
highest average of 25.29 references per paper, while Vol. 34 has the lowest average of
14.82 references per article. Issue 2 has the highest number of references with 1942
(18.06%), Issue 6 placed second with 1878 (17.47%), and Issue 5 with 1855(17.25%)
ranked third.
Conclusion
The global acceptance of bibliometric approaches in various disciplines has resulted in the
significant expansion of literature and its subsequent aspects. The method is effective for a range
of specific purposes, such as journal selection for libraries, illustrating the benefits of a
respective field, assessing scientific development, and ascertaining scientific attributes. These
studies assessed research, pointing the way for new areas to be explored, and journal bibliometric
studies aid in recognizing research phenomena in a particular area of research.
The DJLIT is an important journal in the field of library and information science. The current
study sheds light on the research productivity of the journal articles chosen for the study over the
last ten years. The study is based on bibliometric methods for quantifying major contributions;
assessment of research production also investigates the degree of collaboration among the
contributors. According to this study, the journal's average growth rate was 1.93% per year, with
a degree of collaboration of 0.65%. The study concludes that the authors are attempting to
maximize collaborative writings. This journal on LIS covers a wide range of topics, emphasizing
advanced studies and research.
