Was it a Mir store? Or is it People’s Publication office/bookstore? The book store/publishing house run by ICP? They are still around. They used to stock Progress Publication books too - USSR’s literary cousin of Mir (they’ve stopped stocking Mir now). I am not from Delhi but whenever I’d visit I’d go there to check out some translations, especially Hindi translations of Russian works. I still go - I was introduced to Russian literature in Hindi and I still crave for that. I bought Cossacks’s Hindi translation few months back.
PS. I bought my first IE Irodov in Delhi though. Sunday market.
It wasn't called MIR for sure. People's Publishing House or some variant sounds about right. I am amazed that it's still there - does it occupy a cavernous space in the heart of the circle?
Edit: it's quite possible that what's called PPH now is the inheritor of the space I used to go to, but it's not the same space as far as I can tell from online photos.
PPH isn’t tiny but wouldn’t call it very big either. The only other book store from there I recall was named something like The English Book Store. I’ve been going there since 2004ish only I think. Once in 2-3 years maybe. I’m going to Delhi in a few weeks, if I manage to visit Connaught Place I’ll look/ask around :)
