By applying Bradford’s law to the research productivity of eligible institutions, institutions in various categories /
domains can be categorised into the four groups, namely Most Productive, Medium Productive, Low Productive and
Least Productive as shown in Table 11.

As shown in the Table 11, top 16 HEIs in Overall category (row 1) are most productive that contributed 1,15,378
articles followed by increasing number of HEIs in the remaining three categories contributing matching number of
articles (approximately).

It may be noted that the Least Productive 966 HEIs in Overall category contributed 1,08,109 articles, i.e. equivalent to
number of articles combining 16, 42 and 98 HEIs in the previous three, i.e. most-, medium- and low-productive groups
respectively. Similar observations can be made in all other categories and subject domains. Fig. 10 is pictorial
representation of number of research publications in Overall category that are categorised in four groups, i.e. Most
Productive, Medium Productive, Low Productive and Least Productive.

7.2.3. Comparing Highly Cited Publications (HCP) of Top 100 Institutions vs HCP of Rest of the Eligible
Institutions in Various Domains / Categories

Table 12 and Fig. 11 summarise total number of highly cited publications (HCP) for various categories and subject
domains of India Rankings 2023. Table 12 and Fig. 11 provide a comparison of HCP of top 100 institutions with the HCP
of rest of the eligible institutes in the same discipline / category. As in case of publications, 66.15% of the HCP come
from the top 100 engineering institutions with remaining 1139 participating and eligible engineering institutions
contributing only 33.85% of HCP (row 3). Similar observations can be made from other categories and disciplines.
However, in case of Management. Pharmacy and Research Institutions, 87.01%, 85.07% and 88.23% HCP is
attributable to the top 100 institutions respectively.
