Evaluation of Professor Jafar Mehrad's Scientific Collaborations in Library and Information Science from 1974 to 2021.

Communication is the most fundamental process in research; therefore, scientific communication is the main center of the growth and development of the scientific community. Scientific communication means how scientists in each discipline can disseminate their information and knowledge through formal and informal channels. This is usually done through various media such as books, articles, conference papers, etc. This research has been conducted to investigate the scientific collaborations of Dr. Mehrad, "as an impressive specialist" of knowledge and information science in Iran, using the bibliometric method. The findings showed that about 180 works (including 57 books, 52 Persian articles, 22 English articles, 11 research projects and 38 dissertations) had been published by him. The study of Dr. Mehrad's scientific collaborations showed that 27.8% of the works were published as single authors and 72.2% as the group works. Dr. Dayani is at the top of his scientific colleagues with the publication of 9 works. The journals "Library and Information Science", "Social Sciences and Humanities of Shiraz University", "Information Processing and Management," and" Journal of Academic librarianship and information research" were the four journals in which most of Dr. Mehrad's works were published. The fields of "Library and Information Science", "Databases", "Shiraz University", and "Evaluation" are the core topics in which most of his works have been published. [ABSTRACT FROM AUTHOR]
