Children of all ages can sign up for the summer reading program, “Dream Big — Read” at the Paul Pratt Memorial Library, which runs through Aug. 3. This year, the Friends of the Cohasset Library will donate $1 to Heifer International for each book log submitted to children’s librarian Sharon Moody, with the goal of sending a sheep to a family in a developing country. “Even the littlest one that can hold a book and flip through it” can sign up, Moody said. “You want to encourage literacy from the get-go, and to say you’re too young to read is not right,” she said. Children can register online at www.cohassetlibrary.org or at the library, 35 Ripley Road.
