I am looking for the BORI critical edition of the Mahabharata in Sanskrit, with footnotes, so that I can see the different variations available for a text. I saw archive.org has a few of those pdfs. I am specifically looking for Udyoga parva (Volume 6). A pdf I found on archive.org has poorly scanned pages of Udyoga parva. Can you please point me to where can I get Udyoga parva of the Mahabharata (BORI edition)?
