The Evidence
Children's home libraries are fundamental to literacy
The Research
The affordability of having a home library is the single biggest barrier to literacy development in the United States and beyond. If we can solve the problem of affordability, we will be well on the road to realizing educational parity — a goal which has eluded this country for generations.
A sweeping 20-year study across 27 countries found that the number of books in a home has as powerful an effect on a child's educational attainment as parental education level — and that children from less-educated families stand to benefit the most.
Across 42 nations and more than 200,000 students, the number of books in the home was found to strongly boost children's academic performance — not merely as a signal of elite status, but because home book access builds genuine cognitive skills that schools reward.
Home libraries — even small ones — are among the most powerful and cost-effective tools available for closing the reading achievement gap, reducing summer learning loss, and setting children on a path toward lifelong academic and economic success.
Literacy starts at birth
The Research
The greatest amount of brain growth occurs between birth and age five. In fact, by age 3, roughly 85% of the brain’s core structure is formed. Given the course of brain development, it is not surprising that young children who are exposed to certain early language and literacy experiences usually prove to be good readers later. Just as a child develops language skills long before being able to speak, the child also develops literacy skills long before being able to read.
The American Academy of Pediatrics recommends that pediatricians actively promote shared reading beginning in infancy as an evidence-based strategy that strengthens parent-child bonds, stimulates early brain development, and builds the language, literacy, and social-emotional foundation children need to thrive throughout their lives.
Reading regularly with young children stimulates optimal patterns of brain development and strengthens parent-child relationships at a critical time in child development, which, in turn, builds language, literacy, and social-emotional skills that last a lifetime. The American Academy of Pediatrics recommends that parents start reading to their children at birth.
Parents Make the Difference
The Research
Families are their children’s first and most important teachers, advocates, and nurturers. Strong family engagement is central – not supplemental – to a healthy childhood.
In a longitudinal study of mothers and their infants, shared book reading at 6 months predicted not only continued reading habits but also meaningful gains in parental warmth, sensitivity, and reduced parenting stress by the time children reached 18 months — suggesting that reading together benefits parents and the parent-child relationship, not just children's language development.
Shared book reading programs are an evidence-based strategy shown to strengthen parent-child relationships and improve children's language and vocabulary development.
In focus groups with a racially and linguistically diverse group of parents, families reported that a book provision program positively shaped their home literacy practices, deepened parent-child bonds, and felt culturally aligned with their values.
Summer is Critical
The Research
Providing children the opportunity to take home 10 self-selected books to read over the summer months has been shown to produce comparable levels of reading achievement for all children, regardless of family income.
Giving elementary students from low-income households free self-selected books to take home over the summer produced a statistically significant improvement in reading achievement, with the strongest gains among the most economically disadvantaged children.

Summer learning loss disproportionately affects students from low-income backgrounds and widens achievement gaps, but both school-based and lower-cost home-based interventions — such as book provision and family text messaging — have shown meaningful success in reducing that loss.
