What the National Library of Korea does

The National Library of Korea (국립중앙도서관) is South Korea's national library, a government state entity operated under the Ministry of Culture, Sports and Tourism (문화체육관광부). Founded in 1945 and headquartered in Seoul, it serves as the country's central bibliographic institution, collecting, preserving, and providing access to all legally deposited Korean publications and historical documents. It operates directly with 46 staff as a public institution funded entirely through government budget allocations, providing services free of charge, and it manages two affiliated branches: the National Library of Korea Sejong (국립세종도서관) and the National Library for Children and Youth (국립어린이청소년도서관) in Yeoksam-dong, Seoul.

The library's core technology stack consists of an integrated national library information management system that coordinates cataloging, digital archiving, and inter-library cooperation. Core platforms include the National Bibliography system (KOLIS-NET / 국가자료종합목록), the Onnaru Unified Search (온나루 통합검색) aggregating multiple library databases, the OAK National Repository (국가리포지터리) for digital academic outputs, the Korean Ancient Documents Catalog (한국고문헌종합목록), the Web Resource Archive (웹자원아카이브) for preserving Korean web content, and the National Bibliography LOD (국가서지 LOD) publishing bibliographic records as linked open data. The library also operates the ISBN/ISSN/Legal Deposit System (ISBN·ISSN·납본시스템), ISNI Korea for creator identification, the Book Bridge Service (책이음) for inter-library loans, and the Library Information Naru (도서관 정보나루) portal. Records are classified using the Korean Decimal Classification (KDC) system.

The entity's business model is non-commercial: all services are provided free of charge to citizens, students, researchers, publishers, and institutional libraries, with funding sourced from government budget allocations. There is no pricing model, no revenue generation, no venture funding, and no commercial ownership structure. The customer base spans four segments: the general public and researchers; public and institutional libraries across Korea; publishers and content creators requiring legal deposit and ISBN/ISSN registration; and government agencies needing access to official publications and national records. The distribution model combines physical library locations, a self-serve digital platform at nl.go.kr, and a domestic inter-library cooperation network.
