I think it's a search tool and not a browse/explore tool. You should already know which thing you want by the time you ask amazon to find it for you
I was recently searching Amazon for a specific classic Kindle book with the exact title, author and publisher (Penguin Classics) and still got a list of maybe 500 completely garbage versions that had obviously gamed the algorithm.
Even finally finding the “correct” version in the list, and clicking on that led me to a fake version of the book.
Sadly, the source of the company's bibliographic data at the time flattened the LoC 3-level heirarchy in a way that made it impossible (or at least very difficult) to recover, and I had to abandon the idea. I still think it would have been lovely.
