This is the best book on Irish genealogy ever published. The first volume is a guide to preliminary research. It describes genealogical collections and indexes in all the major Irish repositories and the published indexes, catalogues, and printed sources available in Ireland and the United States. The various chapters detail the types of records that exist and where, the nature and extent of the holdings, dates of coverage, and the existence of indexes to wills and probates, birth, marriage and burial records, land, census and tax records, and church and parish records.
Volume Two is a bibliography of family histories, pedigrees, and source materials published in books and periodicals. It covers such printed works as parish, town and county histories, church records, and family histories. It also has a list of over 1,400 manuscript family histories deposited in public record offices, a survey of the microfilm holdings of various American and Irish institutions, inventories of other manuscript collections, and an index of family history articles appearing in over twenty periodicals.
