Files classified as permanent preservation are files that have reference function for all the work of the socialist cause and even for generations, and files classified as long-term preservation have no extensive social and scientific historical significance.
Documents and materials that need to be searched in the long-term work of this organ are classified as short-term preservation files, which are lower than the above two levels and need to be searched in a short time.
According to "People's Republic of China (PRC) Archives Law" and other relevant regulations, in order to facilitate party and government organs and people's organizations at all levels to accurately divide the file storage period.
The storage period of documents and archives is defined as permanent, long-term and short-term, with the long-term being about 16 to 50 years and the short-term not exceeding 15 years.
To determine the preservation value of archives, we should adhere to the viewpoints of dialectical materialism and historical materialism, and correctly analyze and identify the realistic and historical functions of archives contents.
