From the site, an update:
By end-September, we will be re-developing the site to include full transcription of all of the data on the household forms for 1911, including religion, occupation, relationship to head of family, literacy status, marital status, county or country of origin, Irish language proficiency, specified illnesses, and child survival information.
1901 Census material, with all data transcribed, will be launched between late 2009 and early 2010.
It looks like 1901 has slipped again to early 2010 - however, it is on the way, and it is free - a few more weeks will be well worth the wait I am sure!
(Thanks again Ina!)
