Greetings,
 
Since 2019 we have continued the first full Russian translation of Ramayana. We have finished Sundarakanda. But we still lack Sanskrit commentaries to Valmiki's Ramayana.
We want to go for Yuddhakanda, but can't. Because we have almost no printed books. We use Parab's 1888 Southern editions scan. We would like to find a printed book, but we failed. So we have Tilak's Sanskrit commentary and commentaries quoted in Goldman's English translation.
We need more commentaries.
The website https://www.valmiki.iitk.ac.in/commentaries?language=dv&field_commnetary_tid=13&field_kanda_tid=5&field_sarga_value=1 has helped us a lot for the 5th book, but it has nothing for the 6th and 7th books. It has Bhusana, Dharmakutam, Kataka, Siromani, Tanisloki, Tattvadipika and (partly) Tilaka. But only for the first five books. I'm ready to buy, but these things are not for sale. A scan would be enough, but we can't find a readable scan as well. Can you help us, please?
