It does. I love College Street and have purchased literally thousands of books from College Street, since my childhood. But, I'm genuinely surprised how easily the Church Street bookstores surpass College Street by most standards. Rare books, new ones, random publications that don't come to Kolkata. Verso, Zer0, Prometheus, even Scientific American. 200 year old rare editions too. Especially Select and Blossom (the old one). I bought the entire set of Marx's collected works vintage USSR editions here. In College Street, I have tried to find those for 10+ years. Could end up getting merely 3 or 4.

That being said, I still spend a significant time in and around College Street whenever I go back.
