I had a read of it over the weekend, its very good.
One possible improvement and Im sure there are good reasons of it but could the pics not be in colour?
Seem to lose a lot of detail on some of the pics. Probably a cost think I expect. Maybe in later editions or maybe you could do a limited edition run or something.

Derry or Donegal would be great, do you think you will really be able to include all the sites up there though, would surely be a far bigger book than the one on dublin?
I went back myself over the North Tipp inventory over the weekend for a read and I was kinda thinking I had a look at most of the stuff around but id say I have only looked at 25% of the stuff. So there is probably 75% left that is not marked on the OS maps!
