We admit we’re a little out of our depth with this one as the original question specifically referred to a 1967 match between Aberdeen and KR.
Although we have already outlined some tips for antique hunters looking for Icelandic used books, vintage coins, stamps, and so on, we thought this was also a good opportunity to point amateur researchers and historians to some useful resources.
Tímarit (timarit.is) is an excellent place to begin if you’re looking for anything historical in Iceland. It’s a digitised database of nearly every newspaper that’s been in print in Iceland for the last century, meaning that every day’s headlines reaching back to the turn of the century are available for browsing, free, anywhere in the world. Other periodicals are also available on Tímarit as well.
A quick search turned up the daily news coverage of the match in question, for example.
Another useful resource that’s more specialised, but still worth pointing out, is handrit.is.
At Handrit, you can access digitised versions of manuscripts found in several major manuscript collections, such as the Árni Magnússon Institute for Icelandic Studies, and collections at the National Library of Iceland.
While generally a tool for scholarly research, it’s free to use for all. Amateur historians can, for example, peruse the recently rediscovered manuscripts found in the archives at Handrit, and also access the original sources for much of mediaeval Icelandic literature.
