There is nothing new in this book - it appears to have been sourced from other writers without any new material added - even the latest two GCs entries have factual errors - one has to question the research and the editing -
any work of reference surely requires new information that has been independently researched - i found almost none in this latest book on the GCs.
That all those GCs who are exchange GCs have been excluded is an insult to HM the Queen and her father who created them GCs as well as to those recipients who are still alive. I wasted my money buying this book.
