Hingham Public Library has won a collection of Islamic books, videos, and magazine subscriptions to expand the community’s Islamic reference materials and increase cultural understanding, library staff announced last week. The collection is courtesy of the National Endowment for the Humanities and the American Library Association. The grant also makes the library eligible to apply for a cash award to run a five-part, scholar-led reading and discussion series involving the new materials. In the meantime, library staff will throw a spotlight on the new materials with a talk at 3 p.m. on April 6 by Sharif Mustafa, a visiting professor at Northeastern University. The talk, “Among Muslim Books: A Truce in the Clash of Civilizations,” will address “a topic that clearly fits with the library’s mission of offering resources that promote understanding of diversity and engage people of any and every culture,’’ said Kathy Leahy, who coordinates adult programming at the library.
