Hello again Joy - just been looking on my shelves. It means that I now have empty shelves and lots of books on the floor

Anyway, here are a few:

The Statistical accounts referred to above were done in:
1 Old Statistical Account - 1791-1799
2 Statistical Account - 1845
The first is fascinating to read but take with 'pinch of salt' They were descriptions of each parish in a rough format, compiled and submitted by the minister of each parish - it depended what light he wanted to shed on his territory. The later one is more objective.

I spent a day in Wigtown last time I was down there. It prides itself as being 'the antique book town of Scotland' . So many second hand book shops that they spill out onto the street. I browsed a lot and bought a lot, so came away broke! Some of the shops do an online service. Google Wigtown!
