Just to make my life easier: the bookstore I visited in Paris was not the Avenue Victor Hugo, that closed in Boston two years ago (sadly, it was my favourite bookstore ever). The one that I visited was the famous Shakespeare and Company. Although the books are a bit pricy (9 euros for a Jane Austen paperback, when it was 4.99 GBP seems a bit excessive), it is a lovely little store with a second/first floor that encourages people to just sit and read. Oh and a cat, which sleeps on the books. I have pictures of the cat. Quite a few.
