Frozen in Time: the lost history of Scottish ice hockey 1895-1940 highlights the pioneering days with a particular focus on the inter-war period, when there was a competitive Scottish League with numerous professional imports. There is also a definitive records section.
According to the author: "As the story unfolds, it becomes clear that the debt owed to ice hockey missionaries from the Land of the Maple Leaf cannot be overstated. Ice hockey represents a unique link in the long and happy social relationship which has always existed between the people of Scotland and Canada."
Frozen in Time is published by the Grimsay Press, paperback, 424 pages, and is on sale price £18.95.
I have also added a bibliography of Scottish ice hockey books to this site, with thanks to David Gordon for providing the information.
NB, on a personal note, I'm tickled that one of the most prominent promoters of ice hockey shares my name. Andrew Mitchell donated the Mitchell Trophy which was effectively the 'Scottish Cup' in the 1930s. He was also a director of Third Lanark and helped organise the football club's 1921 tour of North America.
