The British Newspaper Archive has added the Monitor and Missionary Chronicle of the Reformed Presbyterian Church in Ireland to its database.
Twenty editions of the monthly publication, each of about 24 to 26 pages, are available; with only one gap (October 1854), they date from August 1853 to April 1855. It's a very focused newspaper, so may be of interest to those who had Presbyterian ancestors in Ireland, but don't expect general news.
This addition brings the BNA's holding of historical papers published in Northern Ireland to 37, and for the entire island to 143. This same holding is available as the Irish Newspaper Collection as part of a FindMyPast World or Ireland subscription.
