The BRIC is one of three new public spaces created at the Central Library on the Parkway as part of a $35 million, 15-year project to re-imagine a 92-year-old Beaux Arts building trying to remain relevant. The two others are the Robert and Eileen Kennedy Heim Center for Cultural and Civic Engagement and the Marie and Joseph Field Teen Center. Their public debut, in the rear of the library that once housed more than 800,000 books in six levels, is Friday.
