The data is concentrated in VC98 Main Argyll, and particularly in the Lorn area. The geographical distribution of data is uneven as it reflects the localities where recorders are active, but an effort is made to cover the whole of VC98, and places which have few records are deliberately targeted in order to improve the overall balance.
There is also some data from adjacent vice-counties and occasionally from further afield. The majority of records have 8-figure grid references but a number have 6- or 4-figure GR’s.
Lorn is an ancient district in the west of Scotland, now part of the Argyll and Bute council area.
