I’ve been keeping an updated bibliography of publications on Sogdian language and texts for a while now. It amounts to 624 entries, covering from 1904 (when Sogdian was first deciphered and published) to 2020, containing only works that are directly about Sogdian language, linguistics, or manuscripts. It’s more than one might expect for a pretty niche subject like Sogdian, but also certainly less than some related languages like Middle Persian.
I suppose it’s worth trying to do something interesting with all that data, besides just look at it and wish more people were researching Sogdian. So, here are some rough graphs.
We can start with how many publications on Sogdian there have been per year. As we might expect for any field, the rate of publications has increased over the past few decades, with a high of 25 in 2013 and 2017, and a close second of 24 in 2009.
