The Postmaster General's Report series (POST 40 and POST 42) began in about 1790 and comprise reports on all aspects of Post Office organisation in England, Wales and Scotland; as well as those on the Packet Boat service and overseas postal arrangements up to 1807, when a separate Packet Report series (POST 39 and POST 41) was introduced.
POST 40 consists of those actual Reports which are still in existence, with their enclosures (many of which are sketch maps of local postal routes, petitions from the principal inhabitants of towns and villages throughout the country and detailed reports from heads of departments and the District Surveyors, etc). Although, in this list, some of these Reports are shown as 'wanting', many are, in fact, filed within later Reports on the same subject - a common practice of the day. POST 42 consists of volumes containing copies of reports to, and minutes from, the Postmaster General (including those which have since been destroyed), and is the only guide to the contents of POST 40. POST 42/1-25, 35-42, 59-139 and 141 are indexed. The Postmaster General's decision on each case is also recorded.
Post 40/1-3 consist of indexed reports from Francis Freeling, the Resident Surveyor, addressed to the Joint Postmasters General, mostly to Lord Walsingham. They are supplementary to the main series of reports.
Post 40/4-41 consist of reports from the Resident Surveyor addressed to the Postmaster General.
POST 40/42-652 are a continuation of POST 40/4-41, but these reports were made by Freeling in his capacity as Secretary. Freeling was promoted to the vacancy created by the death of Anthony Todd in June 1798, having been created Joint Secretary since March 1797, owing to Todd's incapacity.
Freeling continued the Reports until his death in 1836, after which they were continued for a time by Lieutenant Colonel William Leader Maberly, his successor. From August 1837 Maberly used only the parallel Minute series for his submissions to the Postmaster General. Reports for the period August 1837-February 1841 are quarterly statements of the gross revenue of the Manchester, Bristol, Birmingham, Liverpool and Leeds Penny Posts.
In 1794 a parallel service entitled Postmaster General's Minutes (POST 30 and POST 35) was created, followed in 1811 by a Packet Minute series (POST 29 and 34), corresponding with the packet reports. When the Report series came to an end around 1837 the Minutes were continued alone. The Reports seem to have been the more important of the two series, while the early Minutes were concerned mainly with comparatively minor matters relating to personnel, etc.
