What's the difference between the original edition and the revised edition? When I bought the book, it showed the original edition and the revised edition. Is the original better?
There are some differences, because bestsellers are republished many times, the author sometimes modifies some details or scenes in the book, and some books may add new content or correct mistakes. Probably the main body of the book remains unchanged, and all the modifications are trivial. So they are all genuine. Personally, I think the revised version is better.
