Unfortunately this event was cancelled due to snow. The Library of Congress is closed today.

The Library of Congress Reading Room has been described as the most beautiful room in Washington, DC (The Lost Symbol by Dan Brown), but unless you have a researcher card you’re not allowed inside.  It’s not difficult to get a researcher card but they discourage people from getting them just to check out the room because they are nice, plastic-printed, photo IDs.  With that said, most people don’t get a chance to see this beautiful room except for a small overlook.  Worst of all, photography isn’t even allowed from the overlook so you have no chance to capture the room’s amazing architecture.  However, twice a year, on Presidents’ Day (in February) and Columbus Day (in October), the Library of Congress opens up the Reading Room to visitors and photographers.
