APS buildings are open to staff and invited guests. The Library is undergoing a renovation project that will make many collections inaccessible. It is expected to be completed in early 2022. 

The Library at the APS is undergoing necessary renovations that make maps, prints, and a significant number of collections, especially from the 20th century onwards, inaccessible to staff. Staff will continue to respond to reference requests and to digitize materials, but will be limited in their ability to access some original materials until the renovations are complete.  Completion is expected in early 2022.
