VPRS 12828 Register of General Correspondence Files, Multiple Number System

This series consisted of file registration cards that were part of the multiple number system that was in use from 1973 to 1987. This series was created to register the files created under the multiple number filing system. A card was raised for each secondary heading. All files created under each secondary heading were listed on the one card.The information recorded on the cards included:- Primary Headings and primary number- Secondary Heading and secondary number- Tertiary Number, (ie the file number)- Date file opened, and- File title.Tertiary numbers were allocated to new files at the time of registration of the file. The next available number in sequence on a particular card was used as the tertiary number for the newly registered file. The complete file number had three parts derived from the primary and secondary heading numbers with the tertiary number being the third element.

本系列档案由文件登记卡构成，这些卡片是1973年至1987年间运行的多级编号系统（multiple number system）的组成部分。本系列登记卡旨在登记采用该多级编号归档系统所生成的各类文件。为每一个二级类目（secondary heading）生成一张登记卡，同一二级类目下生成的所有文件均登记于同一张卡片之上。

卡片上记录的信息包括：
- 一级类目（primary heading）与一级编号
- 二级类目与二级编号
- 三级编号（tertiary number，即文件编号）
- 文件启用日期
- 文件题名

三级编号在文件登记时分配给新文件，具体取用特定卡片上按序列排列的下一个可用编号，作为新登记文件的三级编号。完整的文件编号由三部分组成，源自一级类目编号与二级类目编号，其中三级编号为第三组成部分。
