VPRS 6665 Index to Letters

This series was originally transferred to archives with minimal documentation which has not been evaluated. All information currently available to PROV has been incorporated into this series registration. This registration will be updated when further research is subsequently undertaken.

本数据集系列最初移交归档时，仅附带少量未经过评估的文档资料。目前PROV可获取的全部相关信息，均已纳入本数据集系列的注册登记内容中。后续开展进一步研究后，本注册登记信息将予以更新。
