How do I know which version TBR has shipped me? For instance, for the Physics I book, why does it say "January 2016" on the top of the preface page, and says "copyright 2017" on the back of the cover page? Which date should I go by? How about the dates listed on TBR website, why are they older?
Thank you for your time and effort in helping me figure this out 🙂
