I have both researched folk material using local archives and deposited material in them. Archives in my area are just becoming interested in preserving oral tradition, but things move slowly and are subject to funding. One of the best places to preserve stuff and make it available is online but again funding is needed for this. Archives are doing a brilliant job of putting material online currently and we owe it to them to make full use of them and to keep encouraging them in this. Having said all this, as Peregrina says, good old-fashioned paper and ink is still the medium preferred by the archivists as it is the medium that currently lasts the longest.
