Abstract: Bibliometrics is an unique statistical analysis that can be used to analyze a scalable body of academic literature using quantitative methods. Many scholars have used bibliometric analyses to understand research trends (Ellegaard & Wallin, 2015). Bibliometric statistical analysis can include unique sources such as journals, authors, countries, and institutions to help researchers interested on certain topics to grasp the basic information and development status of the literature quickly. A commonly used bibliometric method is citation analysis. Based on the premise that heavily cited articles are likely to have a greater influence on the research field, analysis of the citation scan provides useful information about the journals, papers, and authors that can be considered influential (Pilkington & Meredith, 2009). Co-citation analyses allow researchers to recognize the inherent relationships in the literature and identify the top publications/citations and the major knowledge groups of a specific field of study (Pilkington & Meredith, 2009). The techniques and analysis process will be discussed in detail. This presentation will discuss the state of research conducted and published during the COVID-19 pandemic and the most significant trends emerged at the global level. The analysis includes overview of the focus of the most cited documents and most productive and impact journals in the field of online learning during pandemic (Covid-19) period.
