I hope that someone will find more cuneiform tablets in addition to the 25,000+ found in Hattusa.

I think the first caches of them were found in sites like Mari in Mesopotamia. The Library of Assyrian King Ashurbanipal was huge, and is a large part of the collection at the British Museum.
There’s also better access to such collections, which is good, because not surprisingly a number of cuneiform inscriptions are fragments and haven’t been seen by living scholars in the subject, a number that has never been vast, and as we all complain, the educational system in the US is in a long slow downward spiral.
The Cuneiform Digital Library is a research project at the Penn Museum
