VPRS 12636 File Registration Cards: Multiple Number System

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 heading and primary numberSecondary heading and secondary numberTertiary numberFile 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.

本系列数据集旨在登记采用多编号归档系统（multiple number filing system）生成的各类档案文件。每一个二级类目（secondary heading）均会建立一张专属档案卡，隶属于该二级类目下的全部档案文件均统一登记在同一张档案卡上。档案卡所记录的信息包含：主类目（primary heading）与主编号、二级类目与二级编号、三级编号（tertiary number）以及档案标题。三级编号会在新档案完成登记时完成分配，系统将取用对应档案卡序列中首个可用的编号，作为新登记档案的三级编号。完整的档案编号由三部分构成，分别源自主类目编号与二级类目编号，其中三级编号为编号体系的第三组成部分。
