A Free Book a Month from Dolly Parton's Imagination Library

I just signed my child up for Dolly Parton's Imagination Library. This service, sponsored by the Dollywood Foundation, provides a free developmentally appropriate book a month to any child from birth to five years. Books are selected by a panel of educators, and delivered to the child by mail. Eligibility is by zip code (NYC is eligible), and availability is limited to select areas in the US and UK (though the project continues to grow to support other regions in both countries).
