As an Extension student, you can use the libraries on the UC Berkeley campus. To use reference materials, you must show personal identification. To apply for borrower's privileges at the circulation department, bring your enrollment confirmation and a valid California driver's license. You are eligible for a reduced fee of $25 for six months, payable with a money order or check imprinted with your name and address (cash cannot be accepted). The UC Berkeley collections are also available through interlibrary loan agreements with public libraries.
