For the first time ever, Night in the Stacks will take place on Halloween—and we’re taking over every haunted corner of the iconic McKim Building for a one-of-a-kind celebration. Step inside the Library after dark and uncover Boston’s spookiest stories brought to life through live music by the Sweetbeats band, dancing, delicious food, and an open bar. Guests will also enjoy exclusive access to the brand-new Revolution! 250 Years of Art + Activism exhibition—opening just days before the event.

This night of mystery raises essential funds for the Boston Public Library’s free programs and services. Costumes inspired by gothic literature and Boston lore are warmly encouraged.

This is a 21 and older event. $200 through September 30, $220 October 1 – sold out. There will be an open bar, curated small plates and dessert, live music by the Sweetbeats band and dancing, tarot card readers and a wandering haiku poet, and more. Register at https://bplfund.org/nits/
