Introduction
• Citation analysis is a branch of bibliometrics that
examines the citations found in publications such
as journals and books to look for patterns of use
• This type of study typically involves recording the
details of the reference lists of a number of
publications to determine what materials are
being consulted and
• then analyzing those materials by type,
frequency, age, local holdings, or other factors
Use of citation analysis
• By conducting a citation analysis, a researcher
can better understand scholarly
communication trends within a discipline,
• create bibliographies,
• analyze citation trends of specific user groups,
• determine the extent to which a library’s
collection meets researchers’ needs
Use of citation analysis
Citation analysis are used ;
to rank publications according to their
importance,
to identify core collections,
to measure the impact of publications,
and to study subject interrelationships
Citation analysis for theses
• Common approaches in the literature are to
analyze faculty publications or graduate student
theses for a particular department at a particular
institution.
• Items cited in students’ dissertations show the
resources they used in their dissertation research
and writing
• This type of analysis can yield valuable insights
into local citing trends, such as types and number
of documents cited, accuracy of citations, and
changes in citation patterns over time.
Use of Citation analysis for collection
development
• Effective collection development requires an
understanding of the research needs of users.
• Acquisition librarian should have an
understanding of faculty and student research
needs with academic background or
professional expertise in the field
Use of Citation analysis for collection
development
• Faculty research interests may be identified
from lists of faculty publications, faculty
handbooks, and faculty requests for material
purchases.
• Research needs of graduate students can be
more difficult to discern, but citation analysis
of theses can provide insight into the research
needs of graduate students.
Objectives of the study
• This study analyses citations from 14 master’s
and doctoral theses submitted to the University
of Peradeniya , Sri Lanka between 1995 and 2012
• It is undertaken to analyse the characteristics of
literature used by researchers in the field of
sociology.
• The present study will help the faculty and the
librarians in selection of core journals and other
sources in sociology.

Specific objectives of the study
To understand the citation potential of
the Sociology theses and to know the
various sources of information used by
the researchers in Sociology
 To find out the chronological distribution
and the language of the citations
To observe the nature of authorship
pattern in the literature of sociology
Specific objectives contd…..
To examine the applicability of Bradford's Law
of scattering to the pattern of journals used by
the researchers in Sociology
To examine the core journals of Sociology and
compile a ranking list of journals cited
 To study the distribution of journal citations
by subject and the country of origin
Methodology
• This citation analysis study focused on
Sociology Master and PhD dissertations
submitted to the University of Peradeniya
during period from 1995 to 2012.
• It has identified twelve(12) sociology master's
and two (2) PHD theses accepted at PDN
Library during the period
• Fourteen theses have total of 1603 citations
Methodology contd.
• Citations were extracted from the title pages
and reference lists of each of the dissertation
• The information relating to each citation i.e.,
number of citations, bibliographic form,
number of authors, name of the journal,
subject, country of origin and language were
concerned
Methodology contd.
• The data is fed into the computer using MSExcel software and the Statistical Package for
Social Sciences (SPSS) for analysis
• The data were analysed using descriptive
statistics which includes frequency and
percentage presented in the tables

Chronological distribution of citations Results
• the highest citations were recorded in the period
from 1957 to 1982 with 458 citation counts (
34%)
• 94% of citations were published after 1957
• Five citations that published before 1800 were
found in the Sociology dissertations
• the oldest reference materials in the dissertation
was a monograph which published in 1681
named “An Historical Relation of Ceylon”
Material Age
• Age is the length of time reference materials have
existed and it is usually measured in years
• For calculating the age the difference between
the date of the citation and the date of the
publication in which it was cited considered for
this study.
• Understanding the extent to which library users
rely on older materials can be useful in
determining which materials can be moved to
remote storage
Age of citations
• The age of citations were put into 11
categories: same year, 1year, 2-5, 6-10, 11-20,
21-30, 31-40, 41-50,51-100, more than 100
and Unknown. The results on the age of
citations are presented in the next Figure

Distribution of citations in terms of
Language
This study also examines the language of the
publications cited in order to find the
preferences of sociology researchers on local
or foreign literature.

Authorship pattern- degree of
collaboration
• Collaborative research is the effort of intellectual
sharing of two or more persons.
• The extent of collaboration can be measured
with the help of multi authored papers using the
formula given by Subramanym. (1983)
C=NM/ NM+ NS ( C=degree of collaboration in a
discipline, NM= No. of multi authored
papers, NS= No. of single authored papers)
• C=232/1603=0.144
Degree of collaboration
• The degree of collaboration in the field of
sociology of the present study is 0.144 which
is contrast with the results of previous studies
carried out for the sociology theses. Degree of
collaboration of that study was 0.56.

Authorship pattern- Results
• As explicit in the above table the single
authorship is most prominent.
• More than 85% of the citations are single
authored with 10% having two authors and
2.5% having three authors.
• It further shows that only 1.7% frequency
from total citations had more than three
authors
Journal Citations- Application of
Bradford’s Law
• Journals are vital resources for disseminating results of
new knowledge gained from the research in any
subject field.
• Therefore the journals were further analysed in order
to determine the most cited titles in the sociology
theses.
• This Sociology thesis study contained 356 journal
citations from 139 journal titles. The journals were
placed into three zones according to Bradford’s Law of
journal scattering. (Bradford, 1948)

cited-Results
• The foreign journals are predominating in the
sociology dissertations with having 73% of
journal citations
• The results give insight that sociology
researchers prefer to use foreign journals.
Conclusion
• The findings indicate that the monograph is
the predominant format for sociology
research.
• They support the conclusion drawn in
previous studies that humanities and social
sciences research relies on monographs,
whereas research in the natural sciences and
technology relies on journal articles.
Conclusion
• This study supports the conclusion of previous
studies that cited resources in sociology
research have a longer and flatter age
distribution than in the natural sciences.
• The English language is predominating in the
literature.
Conclusion
• The single authorship appeared most in the
citations while having 97% of cited items in
the print format.
• The findings further identified the core
journals in the sociology discipline
• The most of the journal cited in the theses
were published in foreign countries.
