Researchers support their research work by citing previous studies. Citations are considered important indicator of research performance and many research based indicators are based on these. Self-citation, i.e., citing own previous studies, is a common practice but excessive and unsolicited self-citations are unethical and not considered good. The present paper intends to study the self-citations of “DESIDOC Journal of Library and Information Technology” in terms of author-self citation, journal self-citation and author-journal self-citation during the ten year period from 2010 to 2019. The study also covers authorship pattern, collaboration and prolific authors in the journal under study.
