# Differences between editions of Security Analysis by Graham and Dodd?

Where can I find a comparison of the contents, a list of everything that changed or the differences among the different editions of the book Security Analysis by Benjamin Graham & David Dodd?

There are six editions of the book: 1934, 1940, 1951, 1962, 1988, and 2008.

Do I have to read all of them and compare myself or did someone already do that?

Edit: I already read The Intelligent Investor and the sixth edition of Security Analysis. This question is about the differences between the different editions. The sixth edition if I understand it correctly, is based on the 1940-edition.

• I prefer the 1962 Fourth Edition. It was the last edition written by Graham and Dodd themselves. – user20564 May 1 '16 at 19:07
• @RudyGaranchon can you elaborate a bit more, why is the last version the best? – Bob Jansen May 1 '16 at 20:52

This question is pretty dealt on the internet with; browsing on the web I found a lot of people preferred the 1940 revised edition, but without evident reasons. On the personal finance site suggested to read Graham's Intelligent Investor, considered better than Security Analysis.
