In 1967 Technical Committee No. 2 (Programming Languages) established 'a working group on the problem of formal language description languages for the purpose of creating some order in the area of describing programming languages for digital computers'. Strachey served as a member of this working group from its inception.

Includes correspondence, lists of members, notices of meetings, and discussion of topics to be covered. See also Strachey's correspondence with the Science Research Council (S.R.C.) regarding grants to attend the meetings in MS. Eng. misc. b. 254/B.10, 1967-1974

Strachey's 'Fundamental Concepts in Programming Languages' appeared as Paper 1 in Bulletin no. 1 issued by the Working Group 20 February 1969. (See MS. Eng. misc. b. 292/F.40-MS. Eng. misc. b. 292/F.54).
