Catalogue description SECTION C WORKING PAPERS, NOTES AND CALCULATIONS

The papers are presented chronologically as far as possible, in sub-sections devoted to various stages in Strachey's career (see list of contents overleaf). Strachey's own autobiographical notes make plain that many of his ideas developed from work in progress and flowed into later projects, and the separation here adopted is acknowledged to be an artificial one and is far from implying any break in the work.

These notes and papers were kept by Strachey separate from correspondence and committee files, but should nevertheless be read in conjunction with Sections D and E, and the N.R.D.C. correspondence in Section J, to which cross-references are given where possible. Strachey's own folders, titles and descriptions are retained, and bundles of notes clipped together by him have been left in his order. The early material was rarely dated, and was often written on the back of used papers dated several years previously, or on class exercises from school-mastering days. In these cases, approximate dates and descriptions have been suggested. Very bulky folders have been split for ease of handling, and a note made of their original grouping. Strachey's titles and descriptions are given in inverted commas.

During his employment at N.R.D.C. (1952 - 59), Strachey was principally concerned with the Ferranti computers for Manchester University, designed in conjunction with the Firm, the University and N.R.D.C. Most of these notes are simply headed 'M.U.C.' or appear on worksheets similarly headed, and it has not always been possible to assign them with certainty to a specific task or routine related to the project.
