This year’s event, on Saturday, promises to be bigger and better, with the addition of three venues. Some 130 authors have signed on to participate, up from about 90 last year, and more than twice last year’s 12,000 attendees are expected. The celebration, which takes place in various locations around Copley Square, also will host Boston’s first “One City One Story’’ event, a citywide reading-club discussion of a short story.
The festival, which is the brainchild of Deborah Z. Porter, came about largely thanks to the planning and preparation of an independent nonprofit with a staff of two and a handful of interns. It was an impressive feat, especially considering that some of the nation’s other big-city book festivals are held under the auspices of a city (Baltimore, Free Library of Philadelphia), a college (Miami Dade College), or a major media outlet (Los Angeles Times).
