Telecommunications minuted papers relating to Post Office telegraph and telephone services. 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 the files is consequently often much earlier or much later than the date suggested by the Former Reference used by the registry staff.

POST 30 records concern telecommunications issues in England and Wales, 1792-1952; POST 31 concern Ireland, 1841-1960; and POST 32 concern Scotland, 1864-1966. On its introduction in 1921, POST 33 superseded these sequences and is concerned with telecommunications issues across all these geographies 1921-51, as does its successor in 1949, with POST 102 covering years 1936-76.

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. The diversity and depth of these files can be seen by such examples as the introduction of Bell's telephones to the Post Office (POST 30/330), signalling systems for Belfast and County Down Railway Company (POST 31/74) , arrangements for female telephonists working late duties (POST 32/254D), development of Rugby Radio station (POST 33/1079B), design of telephone kiosks by Giles Gilbert Scott (POST 33/1448), voice recording service for British and Allied armed forces (POST 102/6), telecommunication scheme plans in case of wartime invasion (POST 121/360), and the London to Birmingham television cable linke (POST 122/471).

This series consists of reports, memoranda and accounts relating to the organisation, structure, functions and operations of Post Office factories and the Factories Department.

This series comprises reports, papers, presentations by postal IT staff, handbooks and user guides relating to the different aspects of data processing in the Post Office. Although automatic data processing (ADP) was first introduced to the Post Office on a large scale with the LEAPS system in 1958, POST 113 focuses on ADP in the Post Office from the 1960s onwards. It charts the process of the introduction and implementation of ADP and computer applications and systems to different areas of postal work in order to capture data, streamline postal operational processes and generally improve the daily running of the Post Office.

Examples of material include: a number of reports from the 1960s on new proposals to implement ADP and several files which provide background to: the planning and control of ADP in the Post Office (POST 113/5), the structure of the Computer Development and Office Services Department (POST 113/10) and details of the different computer hardware already in place by the 1960s (POST 113/11).

This series also contains information on the different computer applications and systems proposed and implemented within the Post Office, such as PIVOT (POST 113/23-POST 113/25) and reviews undertaken by the Post Office and external organisations to suggest improvements to existing systems (for example, POST 113/21). In addition, there are files covering the Mails Circulation Project (POST 113/33 and POST 113/34) and the Counter Automation Project (POST 113/38 and POST 113/40).

Finally, there is information on IT strategies within the Post Office and details of the work of the National Data Processing Service (see POST 113/37 for details on the considerations of data protection and computers).There are also examples of computer handbooks and user guides in POST 113/41, POST 113/42 and POST 113/43.

The records of the Commonwealth Telecommunications Organisation reflect the history of Commonwealth co-operation in the field of international telecommunications. The collection is arranged into five general classes:

1. Imperial Communications Advisory Committee, 1928-1945
2. Commonwealth Communications Council, 1944-1949
3. Commonwealth Telecommunications Board, 1949-1969
4. Commonwealth Telecommunications Organisation (CTO), Commonwealth Telecommunications Council (CTC), and Commonwealth Telecommunications Bureau, 1966-1987
5. Commonwealth Telecommunications Organisation (CTO), Commonwealth Telecommunications Bureau and the Commonwealth Telecommunications Council (CTC) after 1987
   Each class represents the surviving records of the body that administered Commonwealth telecommunications relations during a particular period. Within each class, the material falls into three broad categories: the annual reports of the administrative body; the minutes, proceedings and memoranda of that body; the proceedings and minutes of committees and subcommittees appointed by the body. Most of this material is collected, by year, into bound volumes. In addition, the collection contains material (in files and bound volumes) that was not generated by the incumbent administrative body, but does relate to Commonwealth telecommunications during the lifetime of that institution and was presumably retained for use in the course of its activities or for reference purposes. Much of this material relates to the reports and proceedings of the Commonwealth Telecommunication Conferences under whose authority the administrative body derived its mandate. In each class, this material is listed under the heading General Documents.

The subjects in these minuted papers (TCB 2) include satellite communications (Early Bird), international telephone services, policies toward staff and unions, telephone information services (including ship telephone services, roads and weather, teletourist service, speaking clock and the Santa Claus service), and technological developments (including telephone kiosks, the answering machine, "Amplifying Telephone" and "Laryngaphone").

Records of the Business Equipment Trade Association (BETA) and related organisations. The collection includes a complete run of 27 volumes of council minutes, from July 1951 to December 1980. The minutes reflect the association's preoccupation with its role as a public relations body, and with issues affecting its membership, such as VAT or decimalisation. Issues discussed reflect the changing commercial climate, illustrating the increased use of microelectronic technology, although individual products are seldom mentioned unless they are the subject of a dispute. Considerable time is also given over to general internal and administrative matters, and to the continued examination of BETA's aims and activities. Two divisional minute books provide a taste of the activities of the association's sections. Council working papers and correspondence include duplicate minutes of council meetings, reports to council on executive committee meetings, press cuttings, and correspondence relating to association luncheons. A sample of the association's journal is also included.
