West Yorks Rock Art book now on CD

I spoke to Keith Boughey last week and he said the Rock Art of West Yorkshire book is now completely sold out. However the publishers (WYAS) have decided to put the book onto a CD and i think its for sale at the same price as the book (£14.00?) . So at least it is still available in some format. Keith has also put his own 'update' CD together (£5?) with details of some significant finds that have come to light since the book was published.
