And when you are done looking at this site for the Scots input on football world-wide, here are two more.
For those who literally want to trace on the ground the local development of Scots and Scottish football in our own and other countries there is the newly available and ever-expanding site of:
The Scots Football Historians' Group
And on Scottish sports history in general but inevitably including fitba', see Andy Mitchell's inestimable:
Madden and Dick. It may sound like a law-firm, a Glasgow law practice, but they made Czech or rather Prague football and also by extension had with Jimmy Hogan an influence on the Slovakian game. Yet the contrasts between them are notable. One was a Catholic, the other a Protestant. One was a country boy, the other not. One played most of his career in England, one in Scotland. One was a forward, the other a half-back. One played for Scotland, the other did not. They coached rival teams in the Bohemian capital, a rivalry that is as strong today as it was then. One coached Bohemia and then Czechoslovakia. The other did not. One returned to Britain. The other stayed. What they did share was their Scottish-ness, that neither was Glaswegian and a national footballing story.
