Vol. 8 was the Fact Index, this set and the matching dictionary sat in our parlour during my primary school years and I would disappear into there most afternoons and evenings. It was a very 'English' knowledge base but very broad. The subject index style that it used struck a chord with me and made me always look for a way of placing knowledge into context.

I wonder what difference there is between this and the modern universal encyclopedia: the internet? Does any family actually own an encyclopedia set now?
