Question:

How does one go about lookin in a book to see when it was published. As in,if it is the first or sec edition??

I have a Harry Potter and the Sorcerer's Stone book and I am not honestly sure if it is 1st edtion or second. As well as have the other version titled, Harry Potter and the Philiospher's Stone. If anyone can help me that would be great, thank you!
