VOP was undoubtedly one of the greatest series of field recordings ever issued.
Without wishing to detract from that in any way, one of the flaws in the series lay in the notes - mistakes in these ranged from minor inaccuracies to schoolboy howlers, such as in Coochie, Coochie Coo Go Way: (Keach In The Creel - Child 181) from Disc 15 'As Me And My Love Sat Courting'.

And the cat# was standing by" (# should read clerk)

There is a sprinkling of such avoidable mistakes throughout the notes, mainly due, in my opinion, to the fact that the editors chose not to consult the individual collectors on the writing of these notes, rather, choosing to write them unassisted.
As somebody who contributed a number of items to the series, I am sure that these mistakes could easily have been avoided by simply submitting the notes to those who had made the recordings beforehand. This would also have provided more accurate and fuller information on the singers.
It would also have been good manners to do so.
