The material in Dorothy Reich's personal papers covers the years from 1892 to 1981, although the majority relates to the 1950s and 1960s. Her papers include a great deal of material created by Professor Edna Purdie, her teacher and colleague. This is partly due to the fact that on Purdie's death in 1968, Reich took over the editing of 'A History of German Literature' by J.G. Robertson who had also been a Professor of German at Bedford College. Reich's papers therefore include a great deal of material relating to the 3rd and 4th editions of the book edited by Purdie. However, the papers also include material created by Purdie which is unrelated to the publication of the book. The material relating to the revisions of 'A History of German Literature' includes Edna Purdie's correspondence with W.I. Lucas, Professor of German at the University of Southampton, who contributed towards the revisions of the book, and Dr Mary Bearne who assisted Purdie with the section on the Early New High German period. There are also letters from the book's publishers, Blackwood and Sons, about the date of publication for the third edition and correspondence in German between Purdie and the German publishers, Vandenhoek & Ruprecht, regarding a translation of the book into German. There is an extensive collection of handwritten notes and typed manuscripts relating to the revision of the book, including annotated copies of previously published editions. There is also material relating to Henry Handel Richardson, which would have also come into Dorothy Reich's possession through Edna Purdie. Henry Handel Richardson was the wife of J.G. Robertson and was a friend of Purdie's. Her real name was Ethel Florence Lindsey Richardson and she was an Australian author. 'Myself When Young' was her autobiography which she was in the process of writing when she died in 1946. The book was finished by her secretary Olga Roncoroni, with the help of Edna Purdie, and published in 1948. The other material relating to Handel Richardson concerns the publication of a book edited by Purdie and Roncoroni entitled 'Henry Handel Richardson; some personal impressions'. The collection includes material relating to Purdie's career at Bedford College, including papers and correspondence relating to both her teaching and research activities, as well as social aspects of her time at the College, such as her membership of the Wine Association. There are also a number of copies of lectures and publications on the subject of German Literature, which are presumed to have been collected by Purdie. There is a small collection of papers that appears to have been created by J.G. Robertson between 1900 and 1930. These include lectures he gave as well as manuscripts and notes for 'A History of the Romantic Movement', and notes relating to some of his other research topics.

Papers, 1931-1947, relating to the literary work of Ethel Maud Rowell, including offprints of published essays in journals such as the Hibbert Journal, The aryan path and Philosophy, as well as a published copy of her book Time and Time again: essays on various subjects (Allen and Unwin, London, 1941); newspaper cuttings comprising reviews of Rowell's published works, notably Time and Time again; typescripts and manuscripts of essays, stories and poems by Rowell. Correspondence, 1908-1954, relating to publication of Rowell's work, both before and after her death in 1951, including correspondence, 1951-1954, between Professor Elizabeth Marianne Blackwell, Head of the Botany Department at Royal Holloway College, and various publishing firms, concerning the possibility of the posthumous publication of 'Of memory and some other matters', a second collection of essays by Rowell. Miscellaneous documents relating to Rowell, notably a copy of a letter from the Rev Charles Lutwidge Dodgson (Lewis Carroll), 1895 and photographs of Rowell and other staff at Royal Holloway College, [1907-1939].

Papers of Professor Sir William Hunter McCrea, 1890-2004, comprise 10 sections, A-J. Section A: Biographical, presents significant material relating to McCrea's education and career, honours and awards. There are obituaries, interviews and biographical and autobiographical writings. The autobiographical writings consider some of his principal areas of research activity such as 'statistical physics', 'quantum physics', 'Dirac's Large Number hypothesis (LNh) and cosmology', 'solar system problems' and 'Relativity'. Of especial interest for the beginning of his career are the folders of notes made and the 37 notebooks kept by him as an undergraduate and research student at Trinity College Cambridge, 1923-1929, including the period at Göttingen in 1928-1929. Amongst the lecturers and topics represented are P.A.M. Dirac (Modern Quantum Mechanics), A.S. Eddington (Stellar Astronomy), R.H. Fowler (Thermodynamics and Kinetic Theory of Gases), D.R. Hartree (Physics of the Quantum Theory), H. Jeffreys (Operational Methods), J.E. Littlewood (Analysis Theory of Series) and F.J.M. Stratton (Stellar Physics). Also presented here are a series of 'personal' scrapbooks beginning with no. 3 '1960-1967 with a few earlier items' and continuing to the end of his life with no.17 '1993-1997'. The scrapbooks document McCrea's career in photographs, newspaper cuttings, programmes of meetings, invitation cards, table plans, etc. A series of seven 'general' scrapbooks cover the period 1960-1997 and contain principally press-cuttings, especially obituaries. There is also a great deal of other personal memorabilia in the form of invitation cards, programmes, menu cards, seating plans and similar. Many relate to academic occasions, especially in the University of London or scientific occasions, for example at the Royal Society and the Royal Astronomical Society. Section B, University Career, documents a succession of university positions at Edinburgh, Imperial College London, Queen's University Belfast, Royal Holloway University of London and University of Sussex. There is correspondence relating to his early career at Imperial and Belfast, 1934-1944, correspondence and papers relating to Royal Holloway including the Mathematics Department and continuing after his departure for Sussex, 1945-1984, while the Sussex material documents, amongst other matters, aspects of the work of the Astronomy Centre, 1966-1989. However, the largest group of university material relates to McCrea's teaching which is a particularly valuable record for the earlier part of his career at Edinburgh, Imperial and Belfast and continues at Royal Holloway. There is also teaching material for a number of his Visiting Professorships: University of California, Berkeley in 1956 and 1967 and Case Institute of Technology, Cleveland, Ohio in 1964. Also presented here are McCrea's notes on the university teaching of others (subsequent to his own undergraduate and postgraduate education), including E.T. Whittaker and C.G. Darwin at Edinburgh and J. Todd at Belfast.

Section C, Research, is predominantly the contents of McCrea's titled folders which may include manuscript working, drafts, correspondence and off-prints. The folders cover an extended period from 1928 to the 1980s and are presented in chronological order as far as possible. Folder topics include, amongst many others, relativity, 'Milne Theory', stellar models, interstellar molecules and continual creation. Folder titles may also indicate an association with the work of collaborators, for example 'Kermack - McCrea Problems' in the 1930s, and with that of research students, especially at Royal Holloway. Some of the folders contained drafts for identifiable publications and lectures and assignment amongst the sections of the catalogue was not straightforward. Section D, Publications, presents a major chronological sequence of drafts and related material for McCrea's publications, covering the exceptionally long period of seventy years, 1928-1997. The non-availability of a reliable bibliography of McCrea's publications, especially for the period after 1970, meant that the designation of drafts as intended for publication was sometimes tentative. A separate sequence of reviews by McCrea covers the period 1949-1995. Publications correspondence documents McCrea in a number of advisory roles including journal editor. The largest group of papers relates to the Cambridge University Press, 1964-1991 where McCrea was an editor of the Press's General Relativity series and of the Cambridge Monographs on Mathematical Physics from the conception of the series in 1972. Correspondents include fellow editor D.W. Sciama. Of particular interest is a much shorter sequence of correspondence and papers relating to The Observatory Magazine. McCrea became an editor in 1935 and is referred to as a former editor in 1939. Correspondents include fellow editor R.v.d.R. Woolley and contributors S. Chandrasekhar, T.G. Cowling and E.A. Milne, and offering a paper 'as an outsider' J.B.S. Haldane. Section E, Lectures, presents a major chronological sequence of drafts and related material for McCrea's public and invitation lectures, 1931-1993. The sequence documents the great variety of topics on which McCrea talked and the range of his audiences in Britain and overseas from Oslo in 1936 to Brioni, Croatia in 1990. Also presented here are a small group of lectures by other scientists including a notebook used for McCrea's notes of lectures by A.C. Aitkin, W.O. Kermack and E.T. Whittaker, possibly at an occasion at Queen's University Belfast while McCrea was professor there, and a duplicated typescript copy of a lecture on the meaning of wave mechanics given by Erwin Schrödinger in Dublin in 1952.

Section F, Societies and organisations, presents records of McCrea's association with twenty-five UK and international organisations including the British Association, Dublin Institute for Advanced Studies, a proposed UK Institute for Theoretical Astronomy, the International Astronomical Union (IAU), the Royal Astronomical Society (RAS), Royal Greenwich Observatory (RGO), Royal Society and the UK Science Research Council (SRC) / Science and Engineering Research Council (SERC). McCrea's British Association papers cover an extended period 1934-1983 including an early period from 1934 to the beginning of the Second World War when he was involved in various capacities with the work of the Committee of Section A (Mathematical and Physical Sciences). Although the Dublin Institute for Advanced Studies material covers a very short period 1940-1942, this represents the founding of the Institute. McCrea was a member of the Governing Board of the School of Theoretical Physics from 31 October 1940. There is significant documentation of the proposed UK Institute for Theoretical Astronomy, 1960-1966, possible locations being Cambridge (its eventual home) and Brighton. McCrea was a member (later Chairman) of the Subcommittee of the British National Committee for Astronomy which considered the proposed Institute. IAU papers principally relate to its general assemblies and symposia, 1955-1988, the 1935 Paris General Assembly being represented by historical reflections written by McCrea in 1988. McCrea's long association with the Royal Astronomical Society is documented by one of the largest components of the archive. There is a good record in correspondence and other papers of his Presidency, 1961-1963 and of the RAS Club, of which McCrea was President for many years. The most substantial group of RAS papers relates to the history of the Society, McCrea contributing a chapter on the 1930s in the second volume of its history (published 1987) covering the period, 1920-1980. McCrea also had a very long association with the Royal Greenwich Observatory which is extensively documented. There are records of the Admiralty Board of Visitors and its successor, the SRC RGO Committee and of the celebrations of the RGO Tercentenary (1675-1975) in which McCrea took a leading role. He prepared an historical review of the Observatory which was published by the HMSO in 1975, gave a number of papers on the RGO's history and wrote an article for the tercentenary exhibition catalogue. The most significant of his RGO papers, however, are probably those which relate to the decision of the SERC to move the RGO from Herstmonceux Castle in Sussex. McCrea was a very active campaigner against the move. He corresponded with politicians and colleagues and a number of colleagues copied their letters to him. He also wrote on a number of occasions to The Times which published an article by him on 23 April 1986. He attended a meeting of Fellows at the Royal Society, 23 May 1986, and a meeting convened by Patrick Moore, 6 June 1986, to express and to co-ordinate opinions that opposed the SERC's decision. Records of McCrea's Royal Society committee service illuminate developments in British astronomy and space science in the decades following the Second World War. There are also papers relating to two discussion meetings he helped organise: the origin and early evolution of the galaxies in 1979 and the constants of physics in 1983. Finally, McCrea's SRC / SERC material, 1966-1985, provides further documentation relating to British astronomy and space science and the future of the RGO.

Section G, Visits and conferences, provides a useful but incomplete record of McCrea's travel in the UK and overseas to attend all kinds of scientific meetings and conferences. The papers cover the period 1954-1989 and include his Visiting Professorships at University of California, Berkeley in 1956 and 1967, University of Cairo in 1973 and University of Otago, Dunedin, in 1979 and his visits as Royal Society Exchange Visitor to the USSR in 1960 and 1968 and to Egypt in 1981. He was a regular visitor to the University of Liege, Belgium to attend international astrophysical symposia and to the USA to attend Texas Symposia on relativistic astrophysics. Meetings held under IAU and Royal Society auspices are also to be found in Section F. Section H, History of science and scientific biography, represents a major interest and commitment of McCrea. He wrote and lectured on historical and biographical aspects of areas of his scientific interest, especially associated with major anniversaries. He also wrote many obituaries and the Royal Society biographical memoirs of H.H. Plaskett and R.v.d.R. Woolley. There are particularly large accumulations of material relating to Einstein, R.H. Fowler, E.A. Milne, Plaskett, E. Schrödinger and Woolley. Records of his principal historical writing on the Royal Astronomical Society and the Royal Greenwich Observatory are to be found in Section F.

Section J, Correspondence, is extensive and important and is presented in a number of alphabetical and chronological series suggested by McCrea's own arrangement. It covers the period 1942-1996. There is correspondence with colleagues and others relating to all aspects of his work including research, publications, lectures and visits and conferences. There are many examples of correspondence and papers from members of the public and amateur scientists on such topics as cosmology and relativity theory.
