They are indeed two publications - Murray Shoolbraid's is called 'The High-Kilted Muse', published through the University of Mississippi Press in conjunction with the Elphinstone Institute at the University of Aberdeen.

I was initially confused myself, as, like Jack, I know Ian Spring and of his recent publication (it was launched on Sunday 6 June), and around the same time heard mention of the Elphinstone version in their recent newsletter.

I haven't seen Murray Shoolbraid's yet, but Ian Spring's work contains many helpful references to items in the School of Scottish Studies archive (now gradually being published online at www.kistoriches.co.uk / www.tobarandualchais.co.uk )

While the notion of Peter Buchan as a faker persists, he has also been rehabilitated to some extent through the collecting activities of Greig & Duncan, and later Hamish Henderson. It was Hamish who originally brought the SSoS MSS to Ian Spring's attention.
