4 Co-citation analysis
Two publications are co-cited if there is a third publication
that cites both publications (Marshakova, 1973).
4.1 Co-citation analysis of cited authors
Co-citation analysis of the cited authors is presented in
Figure 4 with network visualization. A cited author's
minimum number of citations was considered 30 in this
analysis. Of the 6907 cited authors, 14 met the threshold.
For all the authors, the number of citations and their total
link strengths were evaluated. The authors with the highest
total link strengths were selected. The strongest author was
Gupta B.M. with 173 citations and 38632 total link
strength. For all the authors, the first number stands for the
number of citations and the second one is the total link
strengths. The remaining of the authors are presented in
citations and their total link strengths were evaluated. The
authors with the highest total link strengths were selected.

The strongest author was Gupta B.M. with 173 citations
and 38632 total link strength. For all the authors, the first
number stands for the number of citations and the second
one is the total link strengths. The remaining of the authors
are presented in order; Garg, K.C. (107;21132), Kumar,

Ranganathan S.R.(59; 78), Thelwall M.( 39; 25) and Rao
C.(42; 0).Out of 14 authors, 1 author has not any citation
so, 13 authors are distributed in 3 different clusters
illustrated with different colors that were frequently linked
with each other.

4.2 Co-citation analysis of cited sources
The co-citation of the cited sources is presented with
network visualization in Figure 5. A cited journal’s
minimum number of citations was considered 35. Of the
3046 journals, 20 met the threshold. For those 20 journals,
the number of publications, their citations, and their total
strength of the bibliographic coupling links with other
journals were calculated. The journals with the highest
total link strength were selected. In Figure 5, each circle
stands for a journal, the network of the journal was
demonstrated over different colors. This network
visualization was weighted by the number of citations for
each journal. The top one is the Annals of library and
information studies with 350 citations and 98241 total link
strength. For all the sources, the first number stands for the
number
of citations, and the second one is the total link strength.

documentation (100; 6491), Collnet journal of
scientometrics and information management (62; 29762 ),
