Book "The Theory of Investment Value" 1997 edition & 2012 edition

There is almost no helpful information on both edition and what’s the difference between them. They were all publisehd years after John Burr Williams died.

Anybody has read any or even both of the two? I want to get one but need to know which on to buy. Or is it really good idea to buy it? Thanks.

I generally don’t read books like that. I’ll read what other people say about it, but reading the book itself is usually pretty difficult. Ditto with Graham and Dodd, Adam Smith, and John Maynard Keynes.

Just a personal opinion.
