The Library of Congress is open to the public Monday through Saturday, except for public holidays. Anyone may go there and read anything in the collection. But no one is permitted to take books out of the building.

The Library of Congress was established in 1800. It started with eleven boxes of books in one room of the Capitol Building. By 1814, the collection had increased to about 3,000 books. They were all destroyed that year when the Capitol was burned down during America's war with Britain.

To help rebuild the library, Congress bought the books of President Thomas Jefferson. Mr. Jefferson's collection included 7,000 books in seven languages. In 1897, the library moved into its own building across the street from the Capitol. Today, three buildings hold the library's collection. The library provides books and materials to the US Congress and also lends books to other American libraries, government agencies and foreign libraries. It buys some of its books and gets others as gifts. It also gets materials through its copyright office. Anyone who wants copyright protection for a publication in the US must send two copies to the library. This means the Library of Congress receives almost everything that is published in the United States.
