The Boston Book Festival is an independent nonprofit group based in Cambridge, Massachusetts, and the name of its main event. The nonprofit was founded in 2009 by Deborah Z Porter, and aims to “celebrate the power of words to stimulate, agitate, unite, delight, and inspire by holding year-round events culminating in an annual, free Festival that promotes a culture of reading and ideas and enhances the vibrancy of our city.” The annual book festival combines a street festival with an array of authors and other literary presenters from around the world.
