Diana Panuncial writes: “Sheri Czulno, head library clerk at Chicago Public Library (CPL)’s Vodak–East Side branch, says she doesn’t consider herself much of a reader—but when she was asked to take over the branch’s Masterpiece Book Club in 2012, she knew she had to fulfill Great Expectations. Masterpiece, the longest-running prime-time drama series on television, marks its 50th anniversary this January. Celebrating the series’ ties to literature, libraries across the country have formed book clubs centered on watching the historical dramas and reading the source books in tandem, offering patrons a twofold opportunity to escape to a different world.
