If two books have same ISBN but published in different year, will the contents be the same?

I want to buy a college textbook and searched with the ISBN. The professor indicated the publishing year to be 2009; however, the sellers on amazon/ebay are selling the same book but published in 2008. Will the contents in the textbook be the same?|||I can't answer your question about this specific book, but in general, take a look at the "edition" of the book. If, for example, the 2009 printing is a second edition, you want to make sure the 2008 version is the same. There is a better than likely chance that a newer edition will have updated or revised material. You may want to ask the prof if there is any specific edition of the book he wants you to read. (I'm sure he or she will empathize with you needing to save a few dollars and not buying it form the campus bookstore.)





I hope this helps. Best of luck in your studies.
