First Book, founded in DC over 20 years ago, is a nonprofit that combines the marketplace and philanthropy to get new books into the hands of poor children. The nonprofit operates an online book bank, which collects donated books from publishers and gives them away. It has grown into a national enterprise that gave away more than 15 million new books to low-income children and teens in 2015. More than 215,000 teachers, libraries, health clinics, after-school programs, shelters, faith-based groups and others have “shopped” for kids on First Book. The organization recently expanded its offerings to include other heavily discounted items such as food, clothing and school supplies. Any program is eligible to register with First Book if at least 70 percent of the children served come from low-income families.
