The Margaret K. Troke Library was dedicated on October 13, 1979.  The library's namesake is the late Margaret Klausner Troke, who was the Director of the Stockton-San Joaquin County Public Library from 1946 to 1974.  She was a tireless advocate who fought often and successfully to improve and expand library services in the county and state. Among other things, she is credited with expanding the number of branch libraries and starting mobile library services.
 
The Troke Branch Library is located in north Stockton and serves the largest patron base of all the Stockton branches.  The branch offers a circulating collection of library materials in English, Spanish, Vietnamese, Chinese, Cambodian, Lao, Hmong, and Khmer and maintains permanent and non-circulating reference collections. Newspapers and magazines are available for browsing.
 
The Library offers computer workstations for general use, including printing, scanning, and free Wi-Fi throughout the building.  Computers designated for children are available in the children's area. A public meeting space is available upon request.  The library offers a variety of regularly scheduled programs for all ages and features dedicated children's and teen spaces.
