This study analyzes the evolution and content of Korean information literacy textbooks, proposing future development directions. Starting with 「Information and Media」 in 1996, these textbooks have steadily evolved, becoming more specialized and diverse by 2025 with titles like 「Library Literacy」 and 「Media Information Literacy」. The textbook content is centered on the information utilization process (information seeking and access, analysis and interpretation, synthesis and expression) and deepens progressively with each school level. From the beginning, the concepts of information and media literacy were included, and the Big6 model has significantly influenced the structuring of major units. Recently, the inclusion of new terms like multimodal and multi-literacies reflects an effort to adapt to modern society’s changing information landscape. The study suggests several directions for future textbook development: maintaining information literacy education as a legal term while building an integrated system that encompasses multi-literacies. It is also crucial for professional organizations like the Korean Library Association to establish national standards. Ultimately, information literacy textbooks need to secure their status as official subjects under the ‘Elementary and Secondary Education Act Enforcement Decree’ to strengthen their position within public education.
