This study aims to analyze the current status and issues of parliamentary activity records services provided by the National Assembly Archives and explore improvement measures. To this end, theoretical research was conducted to examine the definition and characteristics of parliamentary activity records, along with case studies comparing and analyzing the parliamentary activity records services of the US Center for Legislative Archives, UK Parliamentary Archives, and Korean National Assembly Archives. In addition, through interviews with National Assembly Archives practitioners, National Assembly members, and researchers, the study explored the perceptions of parliamentary activity records services and discussed current issues and improvements in “search and access services,” “value-added services,” and “utilization promotion services.” In conclusion, this study proposed improvement measures, such as establishing a clear definition of parliamentary activity records, enhancing search tools, strengthening services for National Assembly members’ offices, expanding research support services, reinforcing the independence of the National Assembly Archives, and developing service policies through user needs analysis.
