In 2004, Foclóir na Nua-Ghaeilge, a project of the Royal Irish Academy published Corpas na Gaeilge 1600-1882. As a continuation of that, Corpas na Gaeilge 1882-1926 is now being launched online.
There are almost 300 books published in the Irish language between 1882 and 1926 included in this corpus and over 7 million words. This is a searchable corpus where words or phrases can be located in their original context. Material from periodicals and newspapers of the period will be added later.
Here is where you can search.
