The National Cataloguing Unit for the Archives of Contemporary Scientists (NCUACS), a small unit located at the University of Bath, was established in April 1987 to locate, sort, index and catalogue the manuscript papers of distinguished contemporary British scientists and engineers. The NCUACS was the successor to the Contemporary Scientific Archives Centre at Oxford which operated along similar lines for fourteen years 1973-1987. It was headed by the Director, Mr Peter Harper. The Unit was supervised by an Advisory Committee under the Chairmanship of the Vice-Chancellor of the University of Bath It is important to note that the NCUACS was not itself a repository, and it did not retain the collections it processed. Papers were sorted, catalogued and indexed, and then placed in an appropriate national, institutional or university repository in accordance with the wishes of the donors. They are thus made accessible, subject to any agreed restrictions of confidentiality or library rules of access.
The NCUACS closed in 2009. Their work is being continued by the Centre for Scientific Archives at the Science Museum.
