As early as June 27th, 1986, 10, the State Publishing Bureau issued a notice that the China National Center of the International Continuous Publication Data System began to allocate ISSN. (86) Chu Jiao Zi No.934, which reads: Approved by the State Council1June 985, China announced its participation in the international serial publication data system.
ISDS China National Center is located in Beijing Library. Editors of periodicals in urgent need of ISDS should take the initiative to contact ISDS China National Center in Beijing Library in order to obtain ISSN as soon as possible. At that time, a considerable number of publications applied for ISSN, that is to say, before 1988 implemented the unified domestic serial number, some domestic publications had already obtained ISSN number.
1987 after the establishment of the press and publication administration, the press and publication administration was managed by the press and publication administration and the provincial press and publication administrative department. 1987 On May 9, the Press and Publication Administration issued the Notice on Re-registration of Newspapers, Periodicals and Publishers with the document (87)289.
1987 at the end of July, Publicity Department of the Communist Party of China and the press and publication administration jointly held a meeting on rectifying newspapers and periodicals. At the meeting, arrangements were made for re-registration of newspapers and periodicals. Considering that the China standard publication number has basically taken shape, it will take some time to report it to the State Bureau of Technical Supervision for approval. Therefore, at that time, the relevant departments of the Press and Publication Administration decided to implement the China Standard Serial Number (Draft) as a unified domestic serial number.
