This is the main file system of the District Council from 1989-1993. Some papers from earlier file systems were carried over or copied into these files. In the mid 1990s the files were removed from their original file covers and placed into the current folders, meaning some original context has been lost.
This was originally treated as one big file system from series TDC 00604 to TDC 00612. These have now been identified as unique series in their own rights and have been separated.
