The Londonderry Standard has joined the online database of the British Newspaper Archive.
So far, all bi-weekly editions published in 1837 and all weekly editions published from 1840 to 1843 inclusive have been uploaded, but the site says its holding for this paper will eventually scan 1836 to 1872.
By my reckoning, the addition of this paper means there are now 87 Irish titles in the collection, 23 of them from the North.
All of them are also available via FindMyPast's Ireland and World subscription packages.
