City officials cut the ribbon on Boston’s renovated Central Library in Copley Square on Saturday, marking the completion of the two-phase, $78 million project.

This second phase of work includes removal of the granite plinths that covered the Johnson building windows – reconnecting the building to the street; a revamped lecture hall for author talks and programming, a new innovation center, new Mac and Windows computers for the public computing area, a hi-tech community learning center, an enlarged fiction section and new ways of book browsing, digital stacks to explore the BPL’s digitized collections, a welcome center, a digital imaging suite and landscape additions along Boylston Street, including a table and new trees. The enterprise retail space at the corner of Boylston and Exeter Streets will feature The Newsfeed Café, opening mid-summer and operated by The Catered Affair, and a WGBH News satellite bureau and studio.

The first phase of the renovation, which opened in February 2015, included a colorful children’s library with books and media, early literacy and story time space, a tween corner and flexible program space; Teen Central, a distinctive and media-friendly space with books, digital lab, media lounge, a dedicated quiet zone and homework and hangout booths; refreshed and reorganized nonfiction collections and reference services; and an adult reading area and workspace for individuals and groups.

The Central Library Renovation project is funded by the city of Boston capital budget. In addition to the city of Boston’s Public Facilities Department, the project team includes PMA Consultants as the owner’s project manager, Consigli Construction Co. Inc., as the contractor, and project architect William Rawn Assoc. Architects Inc.

“The goal of the renovation was to reinvent both our building and our library services as inviting, dynamic and modern, to be responsive to 21st century urban civic life and to strengthen the Central Library and its connection to the city,” David Leonard, president of the Boston Public Library said in a statement. “We are proud to welcome everyone, from near and far, to celebrate a new era of library service in Copley Square.”
