I'm curious about whether there happens to be even a rough equivalent to the "green and yellow" commentary series for Greek and Latin available for Sanskrit. For those who aren't familiar, this is a series officially called the Cambridge Greek and Latin Classics, each volume of which basically gives a text (or subunit of one: quite a few cover 1 or 2 books form the Iliad or Odyssey, for instance) with a fairly extensive commentary aimed at least partly at undergraduates. They usually have a fair amount of "literary" commentary, and some translation help, especially on tricky points. The exact details and focus vary quite a bit depending on who the editors are, but some of them are really helpful for intermediate readers.
Anything similar for Sanskrit? What I'd really love is for some parts of the Mahābhārata to be available in anything vaguely like this form. I have and have read the Rāmopākhyāna by Scharf, which is close enough (though unfortunately a bit bulky for the amount of text treated). Anything similar to that would also be fine. But I've been having a hard time finding things in that intermediate stage beyond student readers -- I'm worried that Sanskrit might be a little ill-served in this department, but would love to have my worries put to rest.
I should say that I'd prefer a physical book, if such a thing exists. I don't really like reading online much (eyestrain, and I get distracted). A commentary text in English, French, or German would be fine, but I don't read any modern South Asian languages, unfortunately.
