It's coming back to me now. Before Dave's thesis came online not long after he completed it I tried to obtain a copy from Newcastle. The cost was beyond my pocket but they sent me a microfilm version of it which not having a microfilm reader at the time I took to my local library where I was allowed free to look at the thesis, but the cost of printing off a full copy was again prohibitive. I only had the microfilm for a limited amount of time so eventually I had to send it back without copying it unfortunately. Now I have printed it off and it is phenomenal. I'll be back in a few weeks when I've read it and thoroughly digested it. Many thanks for the links, Ross.
