It is still ongoing, I heard there were enough images in the study for one person to be scanning them up for 3 months in Dublin alone. Thankfully most of them are in the system now.

It differs from the earlier ones in that it comes in one language only – not same text repeated in two languages and the CD ROM is not included. You can register and write in for the CD.
