Bruford (1974), p. 78, note 1: "A selkie is simply a seal, though readers of the ballad [on the selkie] have tended to assume that in itself it means a seal which can take human form". Bruford (1997), p. 120: "'selkie' in itself does not imply the ability to take human form any more than 'seal' does". Bruford, Alan (1974). "The Grey Selkie". Scottish Studies. 18: 63–81.
