Lincoln Record Society

Lincoln Record Society is a British text publication society founded in 1910 which edits and publishes historic records relating to Lincolnshire and the Diocese of Lincoln. The ancient diocese covered not only Lincolnshire, but also Leicestershire, Northamptonshire, Rutland, Oxfordshire, Bedfordshire, Buckinghamshire, Huntingdonshire and parts of Hertfordshire, and the society's publications may touch on the history of all these areas. In practice, they have tended to relate either to the ecclesiastical administration of the diocese (in its several geographical incarnations), or to the broader history of the county
