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.

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.

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.

There may be additional material relating to Davies's lectures and publications in other sections of the catalogue, especially Research and Historical topics and Correspondence.

Papers relating to historical topics, presents important documentation of some of Davies's most important research, such as packet switching, as well as interest he pursued in his spare time such as Second World War cipher machines. These materials were found in Davies's labelled 'transfer cases' or box files which form the basic unit of organisation. There are interesting records relating to early computers organised in relation to a meeting held to celebrate the 50th anniversary of the Pilot Model ACE (Automated Computing Engine) in the year 2000. Packet switching is represented by a sequence 'Historical Notes / Early Packet Switching etc' 1949-2000, which includes copies of original documentation and historical reflections by Davies and others. There is an extensive record of Davies's interest in the history of cryptography including correspondence with others who shared his interests, typescript drafts of articles by Davies, photographs and photocopies of original documentation.
