People who sell books will probably think that Amazon is hypocritical by having a brick and mortar store.
From the pictures, it does look like a typical bookshop except, there is a lot more full face then spine-out.
What does look unique is the way they have linked in their website in the shop. They show on the shelf labels rating, user recommendations and reviews all that are useful information to someone buying particularly if they do not know much about the product. This is something that I think many retailers in many different industries could consider copying.
I think you will get some ideas looking through these photos which are available here.
