The Museum's Sound Archive reflects the activities not only of museum staff in the areas of folklife and transport, but also the work of other interested persons. Topics covered include transport, industry, crafts, folklore, language, traditional music and song, amongst others. The BBC Northern Ireland Community Archive based in the museum holds material broadcast and collected by the BBC from 1924 to the present day. The RTÉ Raidió na Gaeltachta collection consists of material originally broadcast by RTÉ from its Doiri Beaga studios in County Donegal between 1972 and 2002. This is an Irish language facility, dedicated to serving and reflecting the way of life of Donegal Gaeltacht. Currently we hold over 11,000 recordings with approximately 3,500 reels, 1,400 cassettes, 2,100 vinyl discs, 200 CDs and 4000 computer file format.
