I’ll have my colleagues ask around and get back to you.
The library would certainly consider providing space for such an event were someone to organize it; perhaps you could reach out to faculty in the English Dept. affiliated with the Creating Writing Seminar (bit.ly/bc-cw-seminar) or Creative Writing Concentration (bit.ly/bc-cw-concentration), or perhaps students who publish a student literary magazine such as Stylus, Epicenters or Elements. If you would like to schedule an event in library space, contact the administrative office at 617-552-4470.
