This series comprises 'minuted' papers relating to all manner of Post Office matters.
'Minuted' papers were those papers which had been submitted to the Postmaster General for a decision, and then been retained in the Post Office registry. At first, the papers 'minuted' tended only to be the particular case submitted to the Postmaster General but, as time went on, registry staff followed a practice of continuing to add physically to an existing minuted case all other cases on that subject which came to hand. As a result, the minuted papers frequently consist of quite large bundles of files. On a common subject spanning many years. The date range of files is consequently often much earlier or much later than the date suggested by the 'Former Reference' used by the registry staff and, in many cases, the precise dates covered by the files have not yet been listed. The subject of individual files among the minuted papers can be wide-ranging, from the mundane administrative minutiae to policy decisions on developments of critical importance.
