Ordnance Survey 25" County Series Editions

For some counties the 1st edition sheets are arranged by parish name rather than a county grid. Some counties contain part parishes, part grid. This is indicated by grid/parishes.

Where a date is followed by roman numerals, these indicate all sheet numbers produced for that edition. In later editions, OS often only produced sheets where there had been substantial change, rather than a complete new set.
