Hi Nathan - I am new to textbook data management, and thought you may know the answer to this.

I am trying to determine how publishing companies keep track of a unique BOOK so that a prior edition number can be related to a new edition. I suspect there is a unique Identifier that it typically used, but I am trying to confirm what that unique identifier is called. Said another way, how can I know that the 4th edition of Sociology by Tim Jones is in fact the newest edition of the 3rd edition that has the same title and author. THanks for any suggestions!
