Even though people are not so familiar with classical Indian civilization, they were very highly literate and the extant corpus is enormous. It easily rivals or exceeds classical Greek and Latin. I have heard that the Mahabharata is 10 times longer than the Iliad/Odyssey.

On that line of thought, probably it’s Tibetan and buddhism that must have an extensive library. Most of these works have survived for a very long time.

There are thousands of lost palm leaf books, in Sanskrit and other South Asian languages, rotting away.

There is simply no money to support the scholarship that would preserve these works. It's incredibly sad.

Do you know any libraries that need financial support for archiving this body of work?

I know of research institutes, yes.

Sanskrit is widely taught in younger years. Funding needs to go to bright PhD students to make the field again. It's extremely conservative and territorial after so many years of hardship.

I hope they get digitized before they all fall apart. Maybe they should contact google.

They have to be found first. They are mostly scattered in temple basements and private collections.

The whole of modern linguistic theory, including the regular, context-free, and unrestricted grammars, were fully worked out in still-preserved Sanskrit.
