There is some biographical and personal material including several autobiographical notes and narratives, some quite lengthy, on his career and scientific interests, written at various dates from 1963-1994. There is unfortunately virtually no documentation for Series's early life, Oxford University, and college days at St. Johns and St. Edmund Hall, or of his connection with Reading School as pupil and Governor. His appointment, career, and retirement at Reading University are more fully recorded as are his later honors. The surviving research papers represent Series's own selection of topics of special interest to him: some, such as 'Spontaneous emission of light' cover a long time-span 1964-1977, while others such as 'Optogalvanic spectroscopy' are from his last research at Reading 1981-1983. Series seems to have conducted a later revision of some of the material, perhaps in 1990, adding brief explanatory notes on its interest. There is a substantial record of Series's achievement as a popular and prolific lecturer to research groups and conferences, over an extended period, 1959-1988. Publications and editorial papers form only a partial record of Series's considerable editorial committments though it does include material on the founding of the European Journal of Physics with which he was closely involved, serving as its first editor. Visits and conference material are similarly scanty in view of the many conferences and lecture engagements undertaken by Series. Included are several of his visits under the Royal Society Exchange Programme, and also documentation of his major world tour 1982-1983 following his retirement from Reading. The surviving correspondence dates in large part but not exclusively from Series's retirement years. Many of the letters are therefore incoming only, but Series frequently jotted down notes of his replies, or of calculations and ideas arising from the correspondence. He might also, at a later date, add a note on writers' names, careers, and connections.
