During the last three years, numerous research papers have been reported which use social media data to explore several issues related to the COVID-19 pandemic. Bibliometric methods in this work are used to analyze 1427 peer-reviewed documents from the last three years extracted from the Web of Science database. The results of this study show that there was high growth in publications in open access journals with an annual rate reaching 19.3% and they also identify the top cited journals and research papers. The thematic analysis of papers shows that research topics related to social media for surveillance and monitoring of public attitudes and perceptions, mental health, misinformation, and fake news are important and well-developed, whereas topics related to distance-learning education with social media are emerging. The results also show that the USA, China, and the UK have published many papers and received a high number of citations because of their strong international collaboration. [ABSTRACT FROM AUTHOR]

The main objective of this bibliometric study is to examine the publications globally from the Journal of Information Science in the specific period of forty two years (1979-2020). It provides insights into research-based activities. The data was extracted from the Science Citation Index database, Web of Science. This analysis provides information about the document types, yearly published documents within 42 years, top productive authors, top productive institutions and countries, frequently used keywords, and greatly cited articles. These aspects also meet the objectives of the study and provide the major findings such as the majority of the publications are "articles" belong to the Department of Information Science from the UK. That is also a top productive country. The author "Oppenheim C." is on the first position with highest total publications (TP). The highly used keyword is "Information" and the article "Usage patterns of collaborative tagging systems" has the highest ranking in the citation. This bibliometric research will update the researchers about the writing trends, institutions, and the countries involved in research activities. [ABSTRACT FROM AUTHOR]
