    On June 25, hundreds of people came together outside the Library of Congress in Washington D.C, and they were celebrating public libraries. For more than 100 years, libraries have played an important role in keeping American educated. But how are these book- filled buildings changing with the times? You may be surprised to find out.

Benjamin Franklin founded America’s first lending library in Philadelphia in 1731. And the number of public libraries greatly increased in the late 1900s. Andrew Carnegie, a businessman, gave away millions of dollars to help build free public libraries across the country. Between 1886 and 1919, Carnegie helped build 1,679 new libraries!

Carnegie believed that libraries could offer Americans many opportunities. He knew that the more libraries there were, the more people would have opportunities to read books and news. There are more public libraries in America than McDonald’s restaurants now.

The United States is home to 9,225 public libraries. Today , the number of libraries continues to grow. Seven out of ten public libraries offer free Internet use. This can help many community members who can’t go online at home. It can also help them to have the opportunity to find jobs online.

Benjamin Franklin once said, “The doors of wisdom are never shut.” As long as the doors of public libraries are open, his statement is most certainly true!
