If I had a critism of both the Shadows and Ventures books it is only that the index of tunes is counter-intuitive - the name of the tune comes after the reference number.
In an index where one looks for a tune by looking at an alphabetical list (as one does in these books), then the reference number should follow the name of the tune.
ie it should be APACHE [12]
and not
[12] APACHE
