HARVARD LIBRARIES -- PHYSICAL ACCESS Borrowing privileges at the Harvard College Library are available for MIT faculty, research staff, and graduate students. Go to any MIT Reference Desk for eligibility verification. Harvard charges $3.00 for production of a photo ID. Borrowing is available at Cabot, Fine Arts, Kummel, Littauer, Loeb Music, Tozzer, and Widener libraries. On-site access only is available at Harvard-Yenching, Hilles, Houghton, and Lamont libraries. In addition, the following Harvard Faculty of Arts and Sciences Libraries honor the Harvard College Library (HCL) Special Borrower Cards for borrowing or access: Biological Laboratories, Blue Hill Meteorological, Center for Astrophysics, Center for European Studies, Center for International Affairs, Documentation Center on Contemporary Japan, Gordon McKay, Russian Research Center, and Wolbach (astrophysics) libraries. The HCL card is not honored at Baker (business), Countway (medicine), Gutman (education), Kennedy School of Government, Law, and Loeb Design libraries. To obtain a letter of introduction for on-site use, apply at the appropriate subject library's reference desk. Letters of introduction are written to help individuals pursue MIT-related research after other area library resources have been exhausted. We cannot grant letters of introduction for leisure reading purposes. For access to Countway, Gordon McKay, Physics Research, and Wolbach, apply at the Science Library Reference Desk. PLEASE NOTE: Check Boston Library Consortium holdings before applying for a Countway card. Countway should be used only when materials are available at no other local library.
