The new $8.4 million Monroe County Public Library branch in Marathon just opened. The public libraries in Monroe County are centers of information but were built for a time before information works like it does now — on the internet and cell phones. “They’re all retrofitted for today’s technology, where this one is built to accommodate not only today’s technology but tomorrow’s,” said Kimberly Matthews, Monroe County’s library director. By “this one,” Matthews means the new $8.4 million facility in Marathon, one of five branches in the Keys. It’s got a raised floor system to allow for easy transfer of data and power systems around the building. The furniture and bookshelves are also moveable, so the space can be flexible.
