I go on Amazon or other websites to look for a book for school. I put the ISBN number and the right picture of?

the book is the same, Edition is also the same but the published date is different. Is there any difference besides the date.|||If everything is the same, including the edition (it it had been revised it wouldn't be the same edition), then the difference in publication date is probably just that they needed more books to fill orders and ran off another batch of them at a later date.|||It could be a revised edition. Or the softcover and hardcover versions could have different publication dates.
