I would like to know if there is more recent research on the origin of the term (Deva)nāgarī, i.e., when is it first attested, can we correlate its attestation to a specific script, etc. I am aware of the usual reference works on Indian epigraphy/paleography (Bühler, Sircar, Salomon, Falk, etc.), as well as some more recent scholarship that documents the use of a specific script (Nandināgara) for copying a manuscript in puranic sources (De Simini 2016, 110ff.). It seems that we perhaps don't know as many details as we would like, but I thought I would ask a wider audience.  Thanks!

All the Best,

Victor
