Marion Carnegie Library stands on the site of the former “Grandma Cline” residence. This property was acquired in 1914 for the sum of $5,003.17 from Sarelda Cline and her heirs. The building was constructed in 1915, with a grant of $18,000 from the Andrew Carnegie Foundation. Clifford Shopbell of Evansville, IN, designed the building, which was constructed by Robert Sparks of Marion. It was opened to the public on February 29, 1916, with 1,162 volumes and 680 borrowers. Marie Williams Roberts was the first librarian. Mark Woodley was the first president of the board of trustees. The original building faces Market Street, just south of Tower Square in Marion. The library is located in the direct center of Williamson County and is a department of the City of Marion.
