The Library began more than a century ago when the London County Council became responsible for education in London. It was taken over by the Inner London Education Authority and, when ILEA was abolished in 1990, it became the CYM Library (CYM was short for the Centre for Young Musicians, based at Morley College in south-east London). From 1995 to March 2010, it was housed by Trinity College of Music, while retaining its CYM title. The Library has continued to grow in recent years, incorporating sets of music donated from other collections.
With generous support from the Wates Foundation, the Library was transferred to a charitable company, the Community & Youth Music Library – so it is still known as the CYM Library. It is now located in much more suitable premises at Haringey Council’s Hornsey Library, Haringey Park, London N8 9JA.
