Irish Ordnance Survey maps join National Library of Scotland maps platform

A nice piece of news that I have just gleaned from Laragh Quinney from the National Library of Scotland's maps department - Irish OS maps are being added to the NLS maps viewer. Here's the announcement from the latest editions page at https://maps.nls.uk/additions/:

OS Six-Inch Ireland 1st edition maps (1820s-1840s)

We have added online 1,970 maps forming the Ordnance Survey of Ireland's Six-Inch 1st edition series (surveyed 1829-1842). This is the earliest comprehensive mapping of Ireland, showing good landscape detail. Ordnance Survey began work in Ireland in 1824, working initially on creating an accurate triangulation network. The surveying and publication of map sheets generally proceeded from north to south. Ordnance Survey mapped Ireland at the Six-Inch scale before Scotland, England and Wales, and the maps show emerging practices for this series in terms of features, placenames, heights, and engraving techniques.
