There is a short profile of Lord Renfrew as a collector in the Financial Times (Mary Jane Checkland, "My favourite things", November 29, 2008). He talks about his collection of contemporary art and adds a comment on collectors of antiquities:
I’m much in favour of collecting, so long as it doesn’t involve objects recently taken from the ground. In my opinion all too many collections are scandalous for this very reason. I don’t mind so much people buying antiquities looted a century ago, but not if the items in question entered the market post-1970 when the convention on the illegal trade in antiquities was signed.
