STAMFORD — The Ferguson Library’s Harry Bennett Branch is raising money to replace worn carpet throughout the building. The library is asking for donations to replace carpet that in some areas is held together by duct tape at the Vine Road branch. It has already raised $182,000 for the $280,000 project, according to its GoFundMe.com page. “We have found a new durable flooring product that many other libraries use that is washable and made from recycled content,” it wrote on the page.
