the edition offered for sale is not the edition I received. The edition with the blue background is the edition my daughter's teacher is using in class and the one that was advertised that I thought I was purchasing. I received the 50th Anniversity edition which is black and white. I don't know the differences in the two editions, however I do forsee this to be a problem when her class starts this book and the pages are not matching class assignments.
