This paper considers the purposes, methods, findings, and significance of the British Library LESSEN (Learning Support for Special Education Needs) Project. The focus was on Year 7 students (students aged 11-12, in their first year of secondary education) in ten English secondary schools who were on the Special Educational Needs (SEN) register because of their learning difficulties. Case studies were undertaken in 10 schools located in five Local Education Authorities (LEAs). Data were collected from documents, observations, and an extensive interview program, both within schools and with LEA and school library services staff. Work with individual children was also undertaken, supporting in subject lessons and in the SEN base, as well as assisting in the library to provide an action research element to the investigation. Varying levels of library and staffing were found. Recommendations for future progress are provided. (Contains 25 references.) (Author/SWC)
