The Garden City Public Library partners with several community agencies to assist with services that benefit the public in Garden City as well as throughout Long Island. The Library is now a collection site for used eyeglasses, which are collected through the Recycle for Sight Program run by a local Lions Club. In addition, the Library collects American flags to be discarded for American Legion. The flags are taken to Pinelawn National Cemetery where they are burned and the ashes are buried in sacred ground. Boxes are provided for both collections near the interior doors of the Library.

The Library also accepts donated cell phones on behalf of the Garden City Police Department. The phones are reworked to assist victims of domestic violence, persons with disabilities, and senior citizens as 911 calling devices. In addition, donated cell phones may be given by the police department to the "Cell Phones for Soldiers Program." Cell phones may be left at the circulation desk in the Library.

Twice a year, the Library hosts a blood drive with Long Island Blood Services at the library. In addition, the Library periodically collects non-perishable food in cooperation with the Hauppauge Industrial Association to benefit Long Island Cares, Inc., the Harry Chapin Food Bank, which serves the hungry throughout Long Island. The Library publicizes when the blood drive and food drive are held in the local media and on the library's website.
