I was checking www.archaeology.ie and it seems to have gotten a complete overhaul.

Ive only checked North Tipp so far but it has full archaeological description for each site and the search speeds are much improved.

The North Tipp database seems to included some sites that werent in the original hard copy version so this looks very exciting. I checked South Tipp (which doesnt have a hard copy Inventory published yet) and this doesnt have descriptions yet unfortunately.
