This study analyzed the main research areas of archival studies in domestic master's theses. The publication status was determined by examining 2,225 theses published from 2002 to 2024. Thesis titles were categorized into three areas: research domain, research object, and research focus, with keywords extracted, clustered, and analyzed. The results showed that master's theses accounted for 96.7% (2,152) of the total. Analysis of thesis titles also revealed that the research domain primarily covered “specific records/institutions,” the research object included “utilization / record management / records,” and the research focus centered on “current status and improvement plans.” In addition, examining changes in research areas showed active research across various subjects over the past 20 years, with notable increases in studies on information technology, archival studies, digital archiving, education, and curriculum over the past decade. This study contributes to the field by analyzing research areas in archival studies, providing the foundational data for understanding the intellectual structure of domestic archival studies.
