Multiple ISBNs. Photos have glare due to still in original packing materials.Due to all books being brand new, still in publisher's original shrink wrap, many items are unknown, such as country of manufacture, number of pages, illustrator, etc.We are 100% staffed with volunteers and all our items are donated. All our profits are returned to our local library to help fund children and adult educational programming. Our goal is to get all items dispatched from our location within 24-48 hours; however, we do not have access to our inventory on holidays. We ship by USPS Media Mail when possible and provide tracking numbers. We offer combined shipping when you order multiple items. We are committed to ensuring each customer is entirely satisfied with their purchase. If you have any questions or concerns, please contact us directly.
