This study presents a bibliometric analysis of research on students' perspectives regarding online courses. In this study, publication co-citation analysis, author co-citation analysis, and word frequency analysis methods were used to reveal the structure and transformation of online course literature. Descriptive data such as the distribution of studies in the field by country, institution, and time were obtained from 932 documents from the Web of Science (WoS) database. We used R and RStudio programs for bibliometric analysis. The analyses indicate the decisive role of American universities, researchers, and journals in this field, and the Bradford Law results support this finding. In the study, it was determined that the concepts of "knowledge," "education," "student," "online" and "perception" were frequently included among the concepts that stand out as the output of online course education. Especially with the COVID-19 pandemic, there has been a significant increase in studies on online course opinions and the number of individuals and organizations operating in this field. This situation shows that online education will be at the center of national and international studies in the future and will find a wider place in programs at every level of education.
