Library Of Congress
Its been a dream to visit the library from long time. This time I made sure I did. Library of Congress is the largest library in the world (British Library is very a close competitor). It roughly attracts 1.75 million visits in an year and is a reference library. It has books from all over the world including Kannada books(ಉದಾಹರಣೆಗೆ ಕುವೆಂಪುರವರ ಅನಿಕೇತನ ಕವನ ಸಂಕಲನ, ಎಶಿಯನ್ ರಿಡಿಂಗ್ ರೂಮ್ನಲ್ಲಿ ದೊರೆಯುತ್ತದೆ.).
With a free library card you get to see and study them. The library card is available to anybody with an address proof. Fill up the form online and carry your passport (you don't have to be US citizen or permanent resident. Passport of any country is good) and get your id card in like 10 minutes.
If you have a free day in DC don't miss visiting loc. They have a free tour almost every day and they are wonderful. If you want to follow-up online they have great set of blogs. They also do 140 character updates.
