If RIT doesn't have what you need, you can search ConnectNY, a consortium of New York State Libraries that will loan books to RIT students, faculty, and staff for free.
The Rochester Regional Library Council Access Pass will grant you direct borrowing privileges at participating area libraries. It is available to current faculty, graduate and undergraduate students and professional and research staff at RIT. Access Passes are valid for a maximum of one academic year, from July 1 to June 30, with no automatic renewals.
Please fill out the Access Pass application form to get the process started.
