Includes Strachey's offer to Richards of a post and his outline of projects for the Programming Research Group, and letters by Richards on CPL work at Cambridge, England.

This correspondence, which is almost entirely technical, deals with CPL (and manual), BCPL, KDF9 and general matters relating to the setting up of Strachey's Programming Research Group at Oxford. During the period of the correspondence, either Strachey or Richards was at Project MAC, Massachusetts Institute of Technology, hence the long and detailed accounts of technical projects and problems.

Strachey hoped that Richards might accept a post with the Programming Research Group, Oxford, but he remained to complete his thesis and work on BCPL in America.
