We originally had the bound Atlas instead of the spiral one. I do not recommend it. It falls apart very easily. I believe that the Atlas comes in two different sizes. I prefer the larger one, with greater detail. Test: the Atlas should contain the Dordogne town of St. Amand de Coly. More detail is unnecessary, less detail might make finding out-of-the-way suggestions difficult.

I just came back from a travel bookstore. The two versions of the Michelin Road Atlas are the same in terms of detail. The one with a more compact surface is easier to handle, it is more like a book, but on the other hand, each page represents about half of what is presented on the page of the larger version.

Thank you all for the great info!
