On 16 December, the Seminar on Documentary Collection System Construction of Public Libraries was successfully held at the Guangzhou International Documentary Film Festival, China. The seminar was sponsored by the National Library of China (NLC), Guangzhou Library and Beijing Documentary Development Association, and co-sponsored by Academic Committee on Television Documentaries, China Television Artists Association, and China Federation of Radio and Television Associations.

Ma Li said that documentary was regarded as "National Album", which was an important carrier for preserving national history and national memory in the new era. How to explore and establish a documentary collection and service system covering China's public library system was of equal significance for both documentary and library communities.

Wang Dongbo said that documentary collection had important structural significance in the construction of national document resources system. As the representative of modern audio-visual literature, documentary was an important complement to the traditional paper literature in libraries. The NLC planned to establish a more perfect and comprehensive literature resource system to inherit civilization, promote culture, serve the society and benefit the public.

Chen Dali believed that documentary, as a real image carrier of the era, kept files for the country and the future. It was the dream of generations of documentary producers to keep documentaries into national collections, which had extraordinary value of the era.

The experts attending the seminar had in-depth discussions and extensive exchanges on the construction of documentary collection system in public libraries. It was generally believed that images and characters, as two different cultural carriers, had the same important value. They complemented each other and jointly built the home of human knowledge and memory. Documentary could preserve historical information to the greatest extent and restore historical truth, which was an indispensable part of library literature collection system.

In recent years, the NLC had been committed to exploring and developing the collection, communication and dissemination of documentaries. In 2019, in cooperation with the China Television Artists Association, the Seventh Research Department of Institute of Party History and Literature of the CPC Central Committee, and Xi'an Municipal Committee of the Communist Party of China and Xi'an Municipal Government, the NLC released 100 excellent documentaries on 70 years of China. In 2020, the NLC collected 102 outstanding documentaries on fighting against "epidemic". In the future, the NLC would explore documentary collection system construction of public libraries in together with relevant institutions, and create a systematic, comprehensive, open and sustainable documentary collection service platform, which would provide documentary dissemination and exchange for contemporary audience, and preserve audio-visual literature and historical materials for future generations.
