This resource is a searchable online catalog of almost 2.5 million sound recordings held by the British Library National Sound Archive (NSA), from pop music to Miss Piggy to tree frogs to oral histories. At present, users cannot listen to or download these recordings, but the site does offer information on accessing them at the NSA and placing orders for copies. The catalog is searchable by keyword, name, title, subject, place, or through an advanced search. The full details for each entry vary by recording type; most have notes on the contents and the quality of the recording or the copy when appropriate.
