I notice from reading the inside cover that the edition of Pressley's Elementary Differential Geometry being sold is apparently the first edition. Only on reading the last paragraph of the product description do we discover that a 2nd edition is available, but apparently not offered for sale on Amazon. Having mistakenly purchased earlier editions of books on Amazon at least twice in the past, I would like to see this information given more prominence.
I checked on the Springer web site and found essentially the same information. Apparently a second edition is in the works, but not yet being sold, or perhaps the paperback is what is regarded as the second edition. But I think my point remains valid. Venders should be clear about the most recent editions.
The point was that edition numbers should be displayed prominently so that customers do not mistakenly purchase an obsolete edition, so that point seems to be still relevant. But I think Amazon has improved in this respect, so I no longer find it a problem.
