Helen Miller, 82, who worked for 38 years at the Free Library of Philadelphia until retiring in 2005 as director of public services, died March 2. As the library’s West Philadelphia area administrator, Miller developed significant collections of African American and Southeast Asian materials and oversaw the opening of three new branches in West Philadelphia. As chief of neighborhood libraries, she administered the operations of 48 branches and three regional libraries, and chaired the Preschool Door-to-Learning Task Force that created preschool centers in all branch libraries. When Miller became the library’s director of public service in 1995, she managed an $18 million Model Urban Library Services for Children grant from the William Penn Foundation, which renovated branch libraries.
