The present study views author self-citations, as a blend of experience and cognition of authors. This paper supports to lay down emphasis on consciousness and cognition of authors while assessing author self-citations.

Comparative assessment of the journal literature produced by laboratories/institutions working in different fields is a difficult exercise. The impact factor of the journals is not a suitable indicator since citation practices vary with fields. The variation is corrected in this study using a measure, the “subfield corrected impact factor” and it i...

Within-field high impact journals in Astronomy are identified by using the Discipline- Contribution Score. This algorithm is iterated to track Science Citation Index/Joumal Citation Reports of non-recognised Astronomy journals. Further multisubfield Physics and multidisciplinary journals’ contributions to Astronomy are measured.

Journal self-citation is one of the crucial bibliometric indicators, which measures the contribution of a journal towards a speciality. Journal self-citation rate is normalised by adapting a two stage refinement. The normalised self-citing rates are compared with external cited rate to know the self and external influence of journals.

He andPao's method of identifying specific discipline journals is improved by adding the citing impact factor and self-citing rate. The proposed indicator strikes a balance by discounting the size of a discipline. And also this indicator paves the way to identify the constituent journals of a discipline. This method was tested in Physics, Applied P...
