These volumes are bound files of correspondence, reports and other papers compiled by Croydon School Board, (1870 - 1903) and its successor, the Education Office of Croydon Corporation, from 1903 onwards. They fall into two groups: those on general topics and those relating to individual schools, (the school portfolios). Many of these sets of papers appear to have been bound up as volumes in 1903 (when education became the direct responsibility of the local authority; in 1914; and about 1932 (when there was a major reorganisation of the education service). The 1920s and 1930s files were kept in spring-backed binders, until they were bound as volumes in the early 1990s. The files seem to have fallen into disuse during World War Two (when, for example, the system of regular annual returns from schools was discontinued) and were only added to sporadically in the 1940s.
