The sellers were extremely correct and the book arrived in impeccable condition. I hesitate on the number of stars, because this is certainly an excellent book for somebody at that level. For myself, I hoped to be buying a book that I could use to identify different species of wild mushroom, using my hobby microscope. I was disappointed to find that the book is far too advanced for me. This is however no reflection upon the sellers, or upon the book - just that it was not the book I should have chosen.
