The History of the Library of Congress

The Library of Congress was established in 1800 by an act of Congress when President John Adams signed the legislation to create a library for the US Congress. The initial funding of the library was $5,000.00, about $119,380.95 today.

The original collection was burned by the British during the War of 1812. Fortunately, then-retired president Thomas Jefferson offered to sell his personal collection of 6,487 books to start the library anew.

In the late 1800s, Ainsworth Rand Spofford advocated for a collection not only for the government but also for the people (meaning you and me). The US Copyright registration and deposit was centralized at the LOC in 1870 which proved to be essential to the growth of the collection.

Construction on the building which houses the library that we see today began in 1873 and was completed in 1897. It was built in the Italian Renaissance style.

The Library Today

All told, there are three buildings in which the library houses its collection: the Thomas Jefferson Building, the John Adams Building (completed 1938), and the James Madison Memorial Building (completed 1981).

In addition to its physical collection, the Library of Congress houses a massive digital library with more than 16 million digitized items. The Library also has a large document and media preservation program, which preserves items for future generations to access.

The Library of Congress is more than just a repository of knowledge; it provides educational programs and services for people everywhere. It is home to some of the world’s oldest and most important works of literature, art, music, and film. It still serves the US government by providing research services for members of Congress and their staff.

The Library of Congress is located in Washington D.C. and is open to the public for guided tours. The building is also home to several exhibitions, including a permanent exhibit of some of the library’s most precious items.
