text:  This is Travel with Rick Steves. We've been talking with Emma Jacobs. Her book is The Littler Museums of Paris, an illustrated guide to the city's hidden gems, reminding us that, yes, you're going to see the Louvre and you're going to see the Orsay, but there's a couple hundred other museums in and around Paris that do deserve your consideration. Emma, clearly you put a lot of work into this book. I'm curious, as you worked on that, is there some overreaching sort of lesson that you'd like your travelers to take seriously so they get the most out of their time in Paris?
