This is a bit of an obscure request but does anyone know the best way to get a whole book collection valued? My father was a book collector all his life and has over 2000, some of which we know are rare, collectible and valuable and some we don’t know about. I contacted an auction house who said they would come and value it, but it turned out they wanted to take some of the books away on the spot and we just want a valuation for now. Any recommendations or ideas would be much appreciated.
