I wish that we’d discovered audiobooks for the car ages ago! A whole lot of library users have apparently wised up to their usefulness in the past few years; I've been asked frequently lately for audiobook suggestions for family car trips. So I’ve made some lists of great audiobooks that can be enjoyed by listeners of various ages, one in CD format and one in downloadable. You might also consider consulting two excellent lists a colleague of mine made: this list of classics on audio and this one for very young listeners.
It’s amazing how much kids will settle down when they’re involved in a story. I tried to find audiobooks that would be interesting and involving for the adults in the car, as well. So go ahead-- plan a summer getaway. Just don’t forget the audiobooks.
Or the barf bags. (But that’s another story.)
