Prof. Adam Winstanley gave an enlightening talk on Census Substitutes at the Royal Irish Academy for the last Expert Workshop of the year. 

Prof. Winstanley's background in Computer Science was apparent in his approaches, having developed some interesting tools, to assist in trying to quantify the coverage of Census Substitutes when compared with the few surviving Census fragments for the pre-20th century period.

Listeners were provided with a greater sense of how complete various Census Substitutes are and, as ever with this topic, left to mourn what was lost in 1922.

We extend our thanks to Prof. Winstanley for his excellent talk, and to those of you who could attend, this workshop or others in 2017.
