The public library is once again offering free wireless Internet access. The wi-fi service, which the library has offered for about the past 10 years, was disabled by a power surge during a storm in July and repairs were recently completed, according to library director Nancy Cappellini. Meanwhile, the library has resumed its Saturday hours, and will be open from 9 a.m. to 3 p.m. Saturdays through next July 1. And this Monday, the Hanson Public Library Foundation is holding a wine-tasting fund-raiser at 7 p.m. at the Olde Hitching Post, 48 Spring St. Tickets are $25 and must be purchased in advance at the library or the Olde Hitching Post. Those attending must be 21 or older. The nonprofit foundation raises funds to support the library.
