Overview
The Library of Congress occupies three buildings on Capitol Hill in Washington, D.C., and holds the distinction of being the largest library in the world by collection size. Its holdings span books, manuscripts, maps, photographs, films, audio recordings, and digital materials, numbering in the hundreds of millions of items.
The centerpiece for most visitors is the Thomas Jefferson Building (1897), a masterwork of Italian Renaissance and Beaux-Arts design. Its Great Hall and Main Reading Room — capped by a soaring dome — are among the most ornate interiors in the United States. Two additional buildings, the John Adams Building and the James Madison Memorial Building, handle research and administrative functions.
Though founded to serve Congress, the Library has been open to the general public for research since the 19th century. Today it also functions as a significant cultural institution, hosting free exhibitions, concerts, lectures, and literary events throughout the year. Admission to the public spaces and exhibitions is free of charge, making it one of Washington's most accessible landmarks.
Before You Go
Visitor Eligibility
Anyone may visit the public areas, exhibition halls, and the Great Hall without a reservation. Access to the reading rooms for research requires obtaining a Reader Identification Card, which is issued on-site to adults and qualifying students. Bring a government-issued photo ID.
Security
All visitors pass through a security screening similar to airport procedures. Large bags may need to be checked at the coat and bag check. Only items needed for research are typically permitted into reading rooms — no food, drinks, or pens.
Check Before You Visit
Hours, exhibition schedules, and reading room availability can change. Verify current information on the official Library of Congress website (loc.gov) before your trip, especially around federal holidays and recess periods when the Library may have altered hours.
Accessibility
The buildings are equipped with elevators, accessible restrooms, and assisted-listening devices for certain programs. Wheelchairs are available at the visitor entrance on request.
Getting There
The Library of Congress is located at First Street SE, Capitol Hill, directly behind the U.S. Capitol building.
By Metro
The most convenient option is the Capitol South station on the Blue, Orange, and Silver lines — roughly a 5-minute walk to the Jefferson Building. The Union Station Metro stop (Red Line) is also walkable in about 10–15 minutes and provides Amtrak connections for those arriving from out of town.
By Bus
Multiple Metrobus routes serve the Capitol Hill area. Check the WMATA trip planner for current routes and schedules.
By Car
Street parking in the immediate vicinity is extremely limited and subject to time restrictions. Several paid parking garages operate nearby. Rideshare drop-off is straightforward given the building's prominent address.
On Foot or by Bike
Capitol Hill is walkable from the National Mall, the Supreme Court, and the Capitol itself. Capital Bikeshare docking stations are located nearby.
Things to See & Do
The Great Hall and Main Reading Room
Even visitors with no research agenda should tour the Thomas Jefferson Building. The ornate Great Hall is open to all, and guided or self-guided tours of the Main Reading Room viewing gallery offer a look at one of America's great interior spaces. Check loc.gov for current tour availability, as access to the gallery can vary.
Permanent and Rotating Exhibitions
The Jefferson Building typically hosts free exhibitions drawn from the Library's permanent collections — historical maps, rare manuscripts, early American documents, photographs, and more. Rotating shows spotlight topics from baseball history to civil rights. Exhibitions are free and do not require advance tickets.
Research in the Reading Rooms
Scholars and curious members of the public alike can request materials through the reading rooms. The Library holds original documents of extraordinary importance — Jefferson's rough draft of the Declaration of Independence, the Gutenberg Bible, and vast photographic archives among them. A Reader Card (free, obtained on-site) is required.
Concerts and Public Programs
The Library's Coolidge Auditorium presents a well-regarded chamber music series, and the institution regularly schedules author readings, film screenings, and panel discussions. Many events are free; some ticketed events sell out quickly. Check the events calendar on loc.gov.
The Copyright Office
For those with professional or creative interest, the U.S. Copyright Office is housed within the Library. Public information services are available, though operational details should be verified directly.
Food & Drink
There is a café inside the James Madison Memorial Building that offers a convenient option for a quick lunch or snack without leaving the Library campus. Hours and menu offerings should be verified locally, as they can change.
For a broader dining choice, Pennsylvania Avenue SE and the surrounding Capitol Hill neighborhood offer a solid range of restaurants and cafés — from casual sandwich shops to sit-down restaurants. The Eastern Market area, a short walk away, has additional food vendors and a weekend farmers market that is popular with locals.
No food or beverages are permitted in the reading rooms, so plan meals around your research time accordingly.

Safety
Capitol Hill is one of Washington's more heavily monitored and patrolled neighborhoods given its concentration of federal institutions. As with any major urban area, basic awareness of your surroundings and standard precautions with valuables apply.
The Library itself maintains a visible security presence. All entrants pass through screening, and staff are on hand throughout the public spaces. Emergency contact in Washington, D.C., is 911 for police, fire, or medical emergencies.
Local Culture & Etiquette
The Library of Congress occupies a particular place in American civic identity — it was established in 1800 to serve the legislative branch and was largely rebuilt after the British burned it in 1814. Thomas Jefferson's personal library formed the core of the reconstituted collection, and his philosophy of universal knowledge informs the Library's expansive collecting mission to this day.
Visitors should be aware that this is a working federal institution. Reading rooms operate with rules designed to protect fragile materials — silence is expected, original items are handled under supervision, and researchers are expected to follow staff instructions. The atmosphere is scholarly and respectful.
The Library's collections deliberately reflect the full breadth of human experience, including materials in hundreds of languages and from cultures around the world. Exhibitions and programs often engage with complex historical topics directly and without sanitizing, which many visitors find valuable.
