The library, which was built in 1961, will host a event on Saturday that will include face painting, balloons, vintage photographs and free birthday cake.
Before the family-friendly fun kicks off, there will be a performance by a local singer from 10:30 to 11:00 a.m., and a brief ceremony featuring a talk by Arlington and Cherrydale historian Kathryn Holt Springston from 11:00 to 11:30 a.m.
The library is located at 2190 Military Road. For more information call the branch at 703-228-6330.
