I can remember when this book was only available as an expensive hardback. I remember once or twice buying it, despite the expense, to teach British background studies. The best thing was the maps. Now the whole thing is online. It used to be called Britain Yearbook, now it is UK Yearbook. Here is the best page to see what’s on offer. And here are the colour maps as a PDF file.
I love the way the Commonwealth is coloured green – it was always pink when I was at school.
