The correct answer to this open question is the following.
La Biblioteca Nacional de España is similar to the Library of Congress in that both were started from a private collection of books.
In Spain, the major public library is the National Library of Spain (Biblioteca Nacional de España). It is located in Madrid, the capital city of Spain. It was established in 17312, founded by King Philip V. It was in 1836 when the library was revoked as a possession of the royal crown and became a public library.
The Library of Congress is renown as the first institution supporting culture in the United States. It was established on April 24, 1800, and is located in Washington D.C. After the War of 1812, the British troops had destroyed many valuable books from the library, so Congress tried to restore the collection and now they claim that the US Library of Congress is the largest of the world.
