[Air-L] Seeking Literature Help

Hello All, I was wondering if fellows here would be able to suggest me some current/recent literature about self-censorship in the context of social media. I am designing a study to examine self-censorship among social media users in the context of Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan). As noted by Dr. Eric Freedman (Michigan State University) that scholars barely scratched the surface of studying the former Soviet Union Central Asian countries. I have located some publications only. Would greatly appreciate for any help! Thanks Bahtiyar Kurambaev
