Hi Martin, I purchased mine from nhbs £67 for both volumes. delivered. So like all books these days not cheap but saying that I think they are worth the cost. If you would like to have a look at them before you decide you are welcome to pop over one evening or day time to have a look at them.

Hi Nick, Thank you for tgd reply, I also tend to my my books from nhbs It will be something I will keep thinking about. My last expensive books were Dick Forsman Flight Identification of Raptors and the Reeber's Wildfowl of Europe, Asia and North America
