You can access a number of electronic resources and databases from your home computer through the Alumni and Friends gateway, using your UNI and password. You also have lifetime visiting and reading privileges (borrowing privileges cost $30 per month) at all Columbia University libraries. NOTE: To activate those privileges, you must first register with the Library Information Office at Butler Library and obtain a University ID card (This can only be done by visiting Butler Library. Please make sure to bring a government-issued photo ID with you.) For more information, go to Using the Libraries (on the Columbia Libraries site).
