Well one thing to know it is by poll from this forum and from your associate. US have diff. books I guess its time for GB to have books on diff. denomination like other specialized book from copper up,well CCGB 2007 is the first book posted in world books in coinlink, CCGB is not enough to cover the GB coin in one issue that is only my opinion,Maybe CCGB with volume issue per year for modern,victorian,milled or celtic.but the result the failure and success of selling the volume is risky depends on how many will buy,I quoted this on one of my post. Their is also a photograding books also saw in coinlink. For me I have still lot of things to learn but expert who have a personal notes and other find not know and recorded that is still something else if it exist
