In this study, the content and scope of police (administrative) law and police administration textbooks published in Korea before 1982, when the National Police University’s Intoduction to Police Science was first published. Through the RISS(Research Information Sharing Service) academic database, related search terms were specified for category books, and a total of 6 textbooks, including 4 textbooks of police (administrative) act and 2 of police administration, were obtained and analyzed based on the external structure and content. The analysis results are summarized as follow. First, all textbooks published at the time were led by authors who had lecture or practical experience in the police field. Police-related studies have grown and developed into specific academic fields of public administration and administrive law, and in this process, it was understood that understanding police practice was an important asset. Next, it was confirmed that the police act and police administration textbooks were discriminatory in content and composition, regardless of the identity of the titles. Lastly, it was confirmed that there are limitations in evaluating the 1982 Introduction to Police Science as a simple mixture of the police act and police administration. Although much of the important content covered in related textbooks is passed on to Introduction to Police Science, there are also contents that can only be found in Introudction to Police Science. It can be understood that plice science has strived to pursue academic independence since its inception, and these efforts have been reflected in textbooks. Based on these analyses, some policy-level suggestions were also presented.
