We had a poor month selling, so there is a 12-hour sale (30% off) on historical Twitter data access: sifter.texifter.com The good news is that we have (I think) passed muster for another year (our 8th) of Twitter compliance and we will be offering access for academic research for another year. This means no more looking at deleted Tweets, among other things, but also a growing array of tools and collaboration opportunities as we build deeper ties to Twitter and also (it seems maybe) Facebook, as well as academics, librarians, department chairs, and research personnel at institutions around the world. https://discovertext.com/2018/08/28/discovertext-resources/ ~Stu -- Dr. Stuart W.
