Saying they may need to reduce hours due to the COVID-19 pandemic, New Canaan Library officials are spotlighting their expanding and increasingly sought-after digital offerings. Though she’s hopeful the library won’t have to cut back its hours, Executive Director Lisa Oldham said fewer patrons have been coming into the physical building since the virus began surging again last month. “As cases and hospitalizations go up, we know more people are being more cautious and staying at home,” Oldham said. Those people still can access a wide range of materials, she said, as they have been doing in increasingly high numbers since the onset of coronavirus disease earlier this year. Borrowing of e-books has increased 100% year-over-year since March, and children’s and teens digital circulation has risen 250%, Oldham said.
