On site access and borrowing privileges:
With two exceptions, only you can use your library card to check out library materials. Exceptions to the rule are professors and students/staff with long term disability or illness.
If you are a professor, you may give permission to someone else to check out materials on your behalf. Use our Designated Borrower form to request permission. Please note, a designated borrower account does not allow the designee to access Your Account or ILLiad.
If you are a student and have a long term disability that requires this service, please contact Student Support Services. Staff should contact MIT Human Resources. Both departments will assist you in obtaining this privilege from the Libraries.

Request the item through Your Account or contact a library service desk. Library staff will search for the item for you.
