Located in central London by the Guildhall, and open to the public since 1873, the Library is a major source of printed historical and genealogical material, despite the losses sustained during the Second World War. It is particularly strong in all aspects of the history of London. The Record Office houses the archives of the City of London, including parochial records, ward rate books, the records of the City's livery companies, and the archives of various fire insurance companies, individual families, estates, businesses, societies, schools, and other institutions, including the diocese of London and St Paul's Cathedral. The records range in date from the 11th century to the present day. The Print Room has an unrivalled collection of prints and drawings relating to London and south‐east England.
