Can anyone recommend bookstore/s in Paris where we could buy road maps for different areas of France including Corsica?

I believe there is a huge book, record, video store near the Louvre that has a travel section with all kinds of maps. I am thinking it is a Virgin store, but someone might know better than I.
Also, the department stores like Le Sanmartine(sp?) have book departments with maps.
They had all of the Michelin maps when I was there. It included the full range of numbers.

Any newsagent and many tabacs will have a rotating rack of Michelin maps. You can also buy them at any good-sized bookstore outside France or order them from Amazon.com or a travel bookstore or ... There's a spiral bound book with maps of all of France, which is nice for planning a trip, but way too unwieldy to pack.

Michelin also puts out a 5"x7" spiral bound "Atlas Routier" which is very handy for major roads. We actually take along the larger version on our driving trips.

I would imagine that the large bookstore chain FNAC would have them. There are at least a few throughout Paris; one for sure in 6th, nearing Montparnasse.

FNAC definitely carries maps. I would recommend the large Atlas Routier et Tourisique (about 18 euro), which is very detailed and is great for planning future trips.
