Summer means lots of road trips and often we get more questions at the desk about recommendations for audiobooks that everyone can listen to. It's a great idea to have a couple of titles you can mention off the top of your head.
Audiofile, the audiobook magazine, has a website you can use as a resource. Their Family Listening page has author interviews, featured narrators, and 3 recommended lists: for young adults, for 8-12 year olds, and for 4-8 year olds.
There's also a link on that page to their Audiobooks on the Go Summer Listening for Kids & Families 2009 list. It's separated into four sections (Other Times & Places, Classics, Fantasy Worlds, and Family & Community) and has recommended listening levels for each book. Most of the titles are for grades 4 and up, but there are some in each category for K-3.
Don't forget about Tales' Treehouse! To search for audiobooks, type in "Listen to This" in Mr. Crow's search box. Many books listed in the Treehouse have "get the CD" links, but the audiobooks that are specifically recommended are tagged "Listen to This."
