- All children between birth and five years of age are eligible to receive the free books, without regard to family income, as long as there is a local Imagination Library affiliate in their county. The Sullivan County Imagination Library (SCIL) is the affiliate for Sullivan County, Tennessee. This includes all cities and towns in the county, such as Kingsport, Bristol, Piney Flats, Blountville, and Bluff City.
- In order to receive the free books, parents/guardians must register their child with the local affiliate.
- Children receive an age-appropriate book of their very own in the mail each month until they reach five years of age—sixty books in all if signed up at birth.
