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.
The society published an edition of the chronicle of Louth Park Abbey in 1891, but this was to prove its only publication, and shortly afterwards it faded from view.
[5] Prominent supporters (albeit at a distance) over several decades included the historians Frank Stenton and his wife Doris.
Nine volumes of registers were published (seven of them edited by Canon Foster); but the series had to be abandoned as printing costs rose in the 1920s.
The society offers research grants, for sums ranging from £500 to £5,000 (with a possibility of renewal), for projects falling within its areas of interest.
