Why are Irish records so weird?

Not all Irish records were destroyed in 1922, but the burning of the Public Record Office in that year did leave an immense gap. As a result, Irish genealogical research has to deal with idiosyncratic, fragmentary and sometimes marginally relevant records in ways that can seem very strange to those used to British, US or Australian sources. In addition, Ireland came late to digitization and has done it unsystematically. To be polite. This talk unravels the ways in which marginal records have become essential for Irish research, and the peculiarities in using them online.
