Which is the largest library in the world?

I'll be forever regretful of not going there once on a trip to DC. Plan for at least a week to see that marvelous city.

I hope I can visit it before the wingers burn it to ash. :-/

Green Machine, It has over 173 million items, not just books.

I wonder which library is pictured?

Everyone needs to visit DC..you will never forget it. . We need libraries they are vital..

Player Say what!?, no way. the traffic there scares me. once nearby was enough.
