A great overview of some 200 museums in and around Paris. I wouldn't recommend taking it on a trip, as it's somewhat large, but it is certainly worth perusing in preparation. I had no idea that there were so many. I mean, we'd already been to the Sewer Museum a few years ago (awesome!), but there are also museums dedicated to the freemasons, eroticism and medical history of the army. Well, there's always next time...
