The Manuscripts Section of Guildhall Library is the local record office for the City of London (the 'Square Mile'), although it does not hold the archives of the Corporation of London itself which are separately administered. Its holdings date from the 11th century and include the archives of the Diocese of London, St Paul's Cathedral, the City wards and parishes, and over 75 of the City livery companies. It also holds family and estate records, and, in keeping with its location, considerable business and commercial archives. This site offers access to the guide of the Manuscript Section of Guildhall Library.
