Yes you can do that with any resource - borrow from any campus and return to any BHI or CAE campus.
If you are looking at returning resources after library staffed hours, campus libraries have returns boxes or chutes located near each library
City CAE, Elgar and Nelson returns box is located in the study areas of each library.
Elgar has a return chute outside of the library near the bridge walkway.
Lilydale has a returns box right next the entrance of the library.
Whitehorse has a return chute outside of the library on Whitehorse Road.
Have a great day!
