Typically, ILL materials can renewed for an additional 30 days. Remember that requests for renewals of books and other returnable materials received via Interlibrary loan must be granted by the library that is lending us the material.
If you know that you will need the book for longer than 60 days or so, contact the Interlibrary Loan Office , 508 565-1310, as soon as possible. ILL may be able to request a 2nd copy of the book for you from another library.
