Continuously in print through five editions, for more than 60 years, and through nearly a million copies - the primer for many of Americas most illustrious investors - and the wellspring of Graham and Dodds Wall Street immortality - Security Analysis is indisputably the most influential book on investing ever written. Still the investors Bible, its as frequently consulted today as it was when it first appeared in 1934. Of course, over the years and over five editions, Security Analysis changed. Its language was modernized. New material was added. Metaphors and examples were brought up to date. In the light of changing times, these alterations were necessary and appropriate. But what of the original book? The very durability of this work arouses our curiosity. And what we discover when we return to the original is very simply a classic, a work whose uncompromising worth has not paled since it first saw the light of day in 1934.
