not complete copies of the originals and certain information such as covenants and other restrictions may be missing. Information entered includes date of the transaction, names of the parties and a description of the property. From the mid-19th century this also often included a plan of the property. London-wide elected bodies As well as the archives of the London County Council, Middlesex County Council, Greater London Council, Inner London Education Authority and the London Residuary Body, the LMA also hold records of their 19th- and 20th-century predecessors such as the Metropolitan Board of Works, Metropolitan Commission of Sewers, London School Board and the Metropolitan Asylums Board. The records of these bodies are as broad as the functions of modern local government, with documentation on education, housing, health services, welfare, transport, building regulations, drainage, culture and leisure. Many of the different bodies include a series of indexed committee minutes, which often prove to be a valuable starting point when attempting to access the records. Maps The LMA has an extensive collection of maps numbering over 15,000. Many of the maps are split up amongst the various different collections for example tithes maps found amongst the diocesan records and enclosure maps found amongst court records. Fortunately there is a single card catalogue that combines all of the maps from the various collections and has listed them by the area they cover. Twenty of the most popular maps held by the LMA are accessible in the map cabinet in the reference room. These include the first edition of the Ordnance Survey for London 1867–70 and the Second World War bomb damage maps. National records Included in this series are records of the British Waterways Board particularly concerning the River Lea, plans of National Schools in Middlesex and the London Region of English Heritage that took over many of the files and plans of the former Greater London Council Historic Buildings Division. Also featuring in the series of National Records are the archives of Wandsworth (HM Prison) and Wormwood Scrubs (HM Prison). Of the two prisons the Wandsworth records are much more extensive, including administrative and staff records, photographs and prisoners records from 1879. For Wormwood Scrubs the majority of records concern prisoners and begin in 1917. Non-established religions The majority of nonconformist records at LMA relate to the Congregationalist, Baptist, United Reformed and Methodist churches, circuits and missions dating predominantly from the 19th
