The Last Strains of a Language - Mercator Research Centre
In 2001 the Frisian Broadcasting Company Omrop Fryslân has produced a series of five documentary films for the national TV in the Netherlands which shows the position of some minority languages in Eastern Europe and the Russian Federation and the work related to the study and safeguarding of these languages.
The first film in this series describes the reconstruction of historical sound material in the archives of the Pushkinsky Dom, the Russian Institute of Literature in Saint-Petersburg. It shows the collection of Edison wax cylinders and the way material of some endangered languages in Russia can be obtained from these recordings. You can watch it online.
