Delhiites, what's your favourite library in Delhi?

I've always loved exploring libraries around Delhi, and my personal favourites are the Japan Foundation library and the Korean Cultural Centre Library. The atmosphere is peaceful, the collections are unique, and they're great if you're into Japanese or Korean language, culture, manga, literature, or just want a quiet place to read.

I'm looking to discover more hidden gems around the city.

What's your favourite library in Delhi, and why?

I'd love to add a few new places to my list.
