Shelf Subscriptions aren't just for grown-up readers! Our children's book buyer Olivia hand selects books each month for young readers, from baby board books and picture books to chapter books and middle grade titles. The deadline to order a Shelf Subscription for the next month’s delivery is the last Tuesday of each month. Shelf Subscriptions ship on the first Tuesday of every month, and subscriptions are offered for 1, 3, 6, or 12 months.
