Mychal Threets, a Northern California librarian who went viral on Tik-Tok earlier this year, has resigned from his post to focus on his mental health. After amassing 745,000 followers and 15 million likes on the app, Threets says he experienced harrowing cyberbullying on that platform and the social media site X (formerly Twitter). Known online for sharing his unique brand of positivity, mental health support and “library joy,” Threets was named a winner of the American Library Association’s “I Love My Librarian” award for 2023 — one of just 10 winners nationwide from a pool of over 1,400 librarians. “Dear Solano County Library, I just want to say thank you,” Threets said in a Tik-Tok video announcing his resignation.
