The first line of the article calls her “a former teacher” so I took it to mean she was the one working at the NY library.
Edit to add …
Boismier lost her job after she gave students a QR code to the Brooklyn Public Library’s Books Unbanned project. Now she’s in charge of teen initiatives at the library, and will be part of its Freedom to Read Advocacy Institute with PEN America. The free, online four-week training program will teach high school students to combat book banning in their schools and libraries. Source
