Another option if you are in Paris for a couple of days is the Knopf Citymap Guide. It has large scale maps of the city that flip open. Important tourist sites are marked on the map. The text gives location, phone number and hours. Best of all restaurants, cafes, tearooms, bars and shopping are listed for each map with the grid location on the map. Easy to use, small, and good recommendations.
