Kent Memorial Library will change the pace next spring for its fifth annual lecture series. The series, which has focused on topics related to national and international politics and the military since it started four years ago, will shift gears and focus on the arts. Opera singer Marilyn Horne and Meryl Streep have agreed to appear in a series on “Great Performances.” They will discuss their work in an interview format, and the personalities and performances that inspired their careers. On June 24, Streep will be intervieweed by Kent author Frank Delaney. The Kent Memorial Library’s mission is to enrich the lives of individuals and the community by providing materials, programs, and services to encourage reading, learning and imagination.
