How Reading to Your Kids Boosts Their Education, for Free

In 1997, a primary school teacher in La Gloria, on the banks of the Magdalena River in northern Colombia, loaded seventy books onto a donkey. Luis Soriano had noticed that the children in the villages around him had no books at home and no library within reach, in a region where decades of armed conflict had already torn up their schooling. He had two donkeys. He named them Alfa and Beto, which together sound like the Spanish word for alphabet, and he began riding out on weekends.

The teacher with two donkeys

A round trip could run eleven kilometers and take more than eight hours. Alfa carried the books, around 120 of them in wooden cases strapped to the packsaddle. Beto carried Luis. People shouted at him in the street that carnival season was over.

Soriano knew what the distance cost, because he had earned his own degree in Spanish literature from a professor who rode out to his town twice a month. He opened La Gloria's first permanent public library in 2000, then helped start schools in outlying villages. A 2003 radio broadcast brought donations, and the collection grew from his 70 personal books to thousands. In 2010, he fell from one of the donkeys and his leg was crushed and infected, and he eventually lost it. He came back with a prosthetic, using a motorcycle for the first stretch of the route and walking alongside the animals for the rest.

Nearly thirty years on, there is a network of Biblioburro routes across the Magdalena department, and Soriano has not retired.

What the books in a house predict

The reason a man would spend 4,000 hours on a donkey shows up in one of the largest studies ever done on educational attainment. M.D.R. Evans and colleagues at the University of Nevada, UCLA and the Australian National University tracked around 70,000 people across 27 countries over twenty years, asking a simple question: how far did you get in school, and how many books were in the house you grew up in?

The effect held after adjusting for parents' education, the father's occupation and family class position. It was larger in poorer countries than in rich ones. In a follow-up across 42 nations, the researchers found that even a small number of books improved reading skill, so the benefit does not wait until a shelf is full.

Read the finding carefully, because it is easy to over-claim. A home library is a proxy for a whole way of living, and nobody has shown that buying 500 books changes a child's future by itself. Evans calls what she is measuring scholarly culture: books as a normal part of the furniture of family life, which encourages a child to read for pleasure, which does the actual work.

Testing it by mail, at scale

In 1995, Dolly Parton began mailing free books to children in Sevier County, Tennessee, where she grew up. Her father had never learned to read. The Imagination Library sends one age-appropriate book a month to every enrolled child from birth to age five, at no cost to the family. It has now delivered more than 300 million books and mails over three million a month across five countries.

A study led by Claire Galea, published in 2026, surveyed more than 86,000 caregivers in the United States, Canada, the United Kingdom, Ireland and Australia, following families for twelve months and comparing them with families whose children had not yet started receiving books. After roughly ten books, enrolled children showed measurably stronger early literacy, including vocabulary and phonological awareness. They were far more likely to pick up a book and start a reading session themselves, and more likely to grasp basic print concepts such as which way a book runs.

The detail that says the most: in the UK group, households received ten books from the program, and the total number of books in those homes rose by an average of thirty. The free books were pulling other books in behind them.

Treat the size of the effect with some care. The research was conducted by the program's own network and rests on what caregivers reported rather than on independent testing of the children.

Ten books can do what sixty books do

Independent evidence points the same way. A 2020 analysis by researchers in the Netherlands and Australia pooled 44 studies of book-giveaway programs and found that giving books away works. Buried in it is a finding that should change how a family thinks about this.

Bookstart, which hands over one or two books on one or two occasions, performed about as well as the Imagination Library, which delivers sixty books over five years. Reach Out and Read, which gives around ten books through pediatric checkups, sits in the same range. The variable that improved results was not volume. It was whether somebody told the parents why it mattered and showed them what to do.

What free actually means here

Every part of this is available without money. A library card costs nothing. Book giveaway programs cost nothing. Secondhand books cost almost nothing, and thirty in a house is enough to change what normal looks like to a child.

What the research keeps pointing at is access plus a habit. Soriano solved access by putting the books on a donkey. Parton solved it by using the postal service. The habit is the part that happens in your own house, and it is the part the giveaway studies say is worth explaining to parents rather than assuming they know.

How this applies today

Get the card. Whatever else you do, a library card converts an entire building into your home library. The wider question of what else that card unlocks is worth asking at your own branch.

Check whether a book-gifting program runs where you live. The Imagination Library operates in five countries through local partners, and availability is checked by postal code. Similar schemes run through health visitors and clinics elsewhere.

Let the books be visible. The scholarly-culture finding is about books being ordinary furniture in a child's life. A stack within reach at child height does more than a tidy shelf they need permission to touch.

Buy secondhand and accept hand-me-downs without embarrassment. A worn book read four times outperforms a pristine one read once, and the studies counted books, not their condition.

Say why out loud. The single factor that improved outcomes across 44 studies was parents understanding what the reading was for. Tell a grandparent, a neighbor, the friend with a new baby. That costs nothing either.
