667    British Institute of Recorded Sound became the National 
       Sound Archive, then the British Library National Sound 
       Archive and is currently the British Library Sound 
       Archive. Currently we have no materials from its period as
       the British Library Sound Archive, so we have a 'see' 
       rather than a 'see also' reference for that form of name.
