Nice thanks! I'll see if I can dig the Gloucestershire one out of the interweb.
Yeah the Dorset one is a special book now out of print put out by "The Dorset Natural History & Archaeological Society". The Somerset one is in two parts in "The proceedings of the Somersetshire Archaeological and Natural History Society".
I wonder if the Herefordshire list online is complete or if its just the ones which are on the SMR? I know the Somerset one lists several long barrows which were destroyed before Grinsell.
