Soriano, 38, is a primary school teacher who spends his free time operating a "biblioburro," a mobile library on donkeys that offers reading education for hundreds of children living in what he describes as "abandoned regions" in the Colombian state of Magdalena.
In [rural] regions, a child must walk or ride a donkey for up to 40 minutes to reach the closest schools," Soriano said. "The children have very few opportunities to go to secondary school. ...There are [few] teachers that would like to teach in the countryside."
At the start of his 17-year teaching career, Soriano realized that some students were having difficulty not just learning, but finishing their homework assignments. Most of the students falling behind lived in rural villages, where illiterate parents and lack of access to books prevented them from completing their studies.
To help bridge the learning gap, Soriano decided to personally bring books to the children.
"I saw two unemployed donkeys at home and had the idea [to use] them in my biblioburro project because they can carry a heavy load," Soriano said. "I put the books on their backs in saddles and they became my work tools."
In addition to the biblioburro program, he and his wife built the largest free library in Magdalena next to their home. The library has 4,200 books, most of which are donated -- some from as far away as New York City. They also run a small community restaurant.
Soriano's hope is that people will understand the power of reading and that communities can improve from being exposed to books and diverse ideas.
"For us teachers, it's an educational triumph, and for the parents [it's] a great satisfaction when a child learns how to read. That's how a community changes and the child becomes a good citizen and a useful person," Soriano said. "Literature is how we connect them with the world."
