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.

Biographical material is not extensive. An overall sense of Davies's life and work is provided by the contents of his 'Personal' folder of biographical notes, curricula vitae, lists of publications, examples of projects undertaken, etc. There is a little material recording Davies's schooling and university education and some documentation of his career. An unusual insight into the companies for which Davies acted and individuals with whom he came into contact later in his career is given by a collection of his business cards, some annotated. Also documented in this section is Davies's interest in various types of puzzles. There is a little posthumous material, including obituaries. As a number of biographical papers have been retained in family hands, some of the material is photocopy only.

Research material forms the largest part of the collection. These materials were found in Davies's labelled 'transfer cases' or box files which form the basic unit of organisation. There is a sequence of 'Notes of Miscellaneous Scientific Work', covering an extended period, 1952-1996. The contents of many of the containers relate to Davies's security interests with material from 1970s onwards, for example 'Data Security MS Notes', 1978-1984 and 'Public Key Ciphers' (two containers), 1970-1997.
