Using researcher access to Twitter’s full archive, our dataset reveals the frequencies with which strings of text referring to 115 nineteenth-century American poets have been published since Twitter’s launch in 2006. These data reflect the number of extant tweets from 2022-2023 fully citing a given author’s name as of the date the data were pulled. The notebook strictly retrieves circulation counts (“get count”), so the data do not contain any specific tweets, any personal information about Twitter users, or references to their account information and thus aligns with the terms of condition for researcher access to Twitter’s full archive as well as preserves users’ right to be forgotten.
