This is the new one-volume edition of the previous two volumes,
<<ddpub:MacNab Dances Vol 1>> and <<ddpub:MacNab Dances Vol 2>>. 

NB despite the "Isdal" in the title of this publication, it seems clear her middle name was actually "Isdale". See <<https://my.strathspey.org/dd/issue/2305/|issue 2305>>.
