This study conducted a resident perception survey to provide foundational data for establishing the Second Mid-to-Long-Term Development Plan (2026-2030) for Pyeongchang County public libraries. Through online surveys conducted from February to March 2024, responses were collected from 169 library users and 64 non-users to compare and analyze their perceptions regarding library usage patterns, collections, services, programs, facilities, specialization, and future-oriented services. The analysis revealed that users prioritized physical accessibility (71.72%) and print materials (3.93), while non-users preferred digital services and multifunctional cultural spaces, showing higher expectations for future technologies. Based on these findings, this study proposes seven development directions: bridging accessibility gaps through physical-digital convergence strategies, digital transformation, customized programs for different age groups, spatial innovation, smart library implementation, region-specific specialized services, and integrated promotional strategies. This study provides empirical evidence for the sustainable development of public libraries in rural areas facing demographic challenges.
