The Bolton Public Library is joining a growing trend among public libraries across the nation as it unveils a new e-book service designed to expand its book offerings. Through a new service called Freading, patrons can access tens of thousands of new books via an e-reading device simultaneously with any number of users, according to the library’s announcement. Patrons can check the library’s website, www.boltonpubliclibrary.org, for more information about how to connect to the service.
