The Hán-Nôm Collection is the world’s first digital library dedicated to Hán-Nôm studies. Initiated by the Vietnamese Nôm Preservation Foundation in collaboration with the National Library of Vietnam, the project brings together a wide range of materials, including Hán-Nôm texts, Siddham (Sanskrit) inscriptions, gate carvings, and sanctuary placards from two of Vietnam’s oldest and most significant Buddhist temples, Chùa Thắng Nghiêm and Chùa Phổ Nhân. It also incorporates Hán-Nôm texts digitized by both the Vietnamese Nôm Preservation Foundation and the National Library of Vietnam. The collection is currently hosted on the Columbia University Digital Library Collections platform, while the Digitizing Việt Nam website serves as a digital hub, enabling users to explore and engage with these materials through a unified interface.
