Abstract

This study empirically analyzes the impact of the public library registration system, introduced in December 2022, on librarian staffing. Using data from the National Library Statistics System for three years before (2019-2021) and after (2022-2024) the implementation, the study tracked quantitative changes in total librarian staffing and conducted an in-depth analysis of growth patterns and compositional changes between regular and non-regular librarians. Specifically, the study examined the impact of the registration system on employment structures through growth rates and compositional changes by employment type during each three-year period. To this end, a chi-square test of independence was conducted to statistically verify the association between the implementation of the registration system and growth patterns by employment type, and to determine whether the observed changes were statistically significant. Based on the analysis results, the study empirically verified the policy effects of the registration system, identified discrepancies between the policy's original goals and actual outcomes, and derived policy recommendations for future institutional improvements. This study is significant in that it empirically validates the alignment between policy intentions and actual outcomes by analyzing the actual patterns of librarian staffing expansion by employment type following the implementation of the registration system.
