Ximena Conde and Aubrey Whelan write: “The bitter cold of recent weeks was so dangerous that various Philadelphia agencies coalesced around one mission: Get the city’s most vulnerable off the streets. Libraries became a key piece in these efforts, with some branches doubling as so-called warming centers. The mobilization is largely, though not universally, welcomed by library staff, the community groups that support the workers, and the people who use the spaces. But employees say the warming center initiative leaves branch staff unequipped to help some of the people walking through their doors with complex needs.”
