Local histories and journals
Many Catholic parish histories have been written. These books, frequently based on local knowledge gained over a lifetime, can include information of inestimable value, such as details of individual families and place-names.
Many societies produce a journal on a regular basis and these can also be exceptionally useful for researchers. A number of these journals can now be accessed electronically via JSTOR, including Seanchas Ard Mhacha, the Journal of the Armagh Diocesan Historical Society, and Clogher Record, the Journal of the Clogher Historical Society.
Another important journal is Archivium Hibernicum, published annually by the Catholic Historical Society of Ireland, which contains a wealth of primary source material. In a similar vein is also Collectanea Hibernica, which was published by the Franciscan Province of Ireland.
