Like most Parisians, I have a love affair with the metro. It’s not love/hate, as the relationship is for some. I just love it. I love the humming sound of the closing-doors warning, the corny Wall Street English ads and crappy poems posted on the walls of the cars—I even love its smell. It makes perfect sense to organize a guide to Paris around its metro stops. Jim Read has done just that in “Paris and Its Métro.” The 244-page pdf, which you can download for $9.99, is a must-read for residents, too, who will benefit from info on obscure stops they might find themselves at to run an errand. Seemingly charmless points such as Marx Dormoy and Exelmans hold interest that Read expands upon. Sidebars to the main text explain city fixtures such as Wallace Fountains or trivia such as the fact that a potato farms once operated at site that is now the Sablons metro station. Forgive the typos; the simple, conversational style of the guide wards off the kind of boredom induced by more history-heavy tomes. There’s plenty of information here, parceled into bite-sized pieces. I raced ahead to check Read’s review of my own metro stop, Lamarck Caulaincourt. Success! He gave it 5 stars—a “must see” in all caps with an exclamation point.
