When a student from the Burlingame Campus orders a book from the Library we usually send it through the carrier that travels between the 2 locations. That will take only 1 or 2 days, depending on at what time of day it is requested.
To return the book, you may simply give it to the front desk at the Burlingame campus, and they will return it for you. Make sure to watch your due date so you don't have a late fee.
