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:

And on Scottish sports history in general but inevitably including fitba', see Andy Mitchell's inestimable:
Poland
In 1900 and before, as football began its spread across Europe, Poland was not a country. It was an idea but not a state. That would not change until Treaty of Versailles in 1918. It meant both that as the 19th Century became the 20th that football arrived not in Poland per se but that at much same time it might have come from any of three directions. Part of what would become Polish soil was under the control of the Austro-Hungarian Empire to the south, part in the west under Germany and in the east the Russian Empire held sway. However, although the oldest club was in what was then Lwow, now Lviv and not in Poland at all but Ukraine, the initial impulse and early seat of footballing power was Krakow in the south and came not as football at all but from health.
A certain Henryk Jordan, a doctor, had travelled to Britain to train and came, much as William Alexander Mackay would be in Huelva in Spain and Alex Watson Hutton in Argentina amongst others, back to his home town of Krakow of the importance of sport to well-being. There in 1889 he founded The Park of Games and Play, known today as Jordan's Park. He also introduced football and spread the philosophy to students and colleagues. Amongst them were was Eugeniusz Piasecki, and whilst Krakow's KS Cracovia that still today plays in the Polish top division, the doyen of Polish clubs, was founded in 1906, Piasecki had already return to his hometown of Lwow led in 1903 to the founding of two clubs there, including Poland's first club, if one of a Poland that only existed between the World Wars.
In 1904 Piasecki returned to Krakow with a Lwow team and played an exhibition match, which was lost. And it would be the return of a Lwow team in 1906 that would trigger the formation of Cracovia, followed in 1907 by a representative Krakow team travelling in the opposite direction and in 1908 the arrival of an "Englishman", who would not only bring British football to the Silesian capital but also go on to play a similar role in the game in Warsaw. His name is William Calder.
