Archives refer to valuable historical records formed in the past, which can clearly indicate data files with complete records. Judging the value of archive contents can be started from the following three aspects:

1. The degree of completeness of the archives. If an archive is kept relatively complete, then the value of the archive can be judged normally; on the contrary, if the archives are incomplete, the storage period of certain archives can be relaxed and extended as appropriate.

2. The degree of substitutability of the file content. If the file content is included by other more important documents, then the value of the file appears to be less important; on the contrary, if an file can independently and completely reflect one aspect of the content, there is no Other materials reflect the content of the file, and the value of this file is relatively high.

3. The repetition of archives between fonds. During the process of transferring the archives to the archives management department, some identical documents were generated. Therefore, it is necessary to avoid duplication of these documents.

The judgment of the value of archives is to distinguish whether each archive has a preservation value, and to determine the preservation period of the archives. It plays a relatively important role in the preservation of archives. Storage in acid-free paper archive boxes can make the archives long-term mold.
