ILL Borrowing Policies

Making Requests

Place your requests using the secure online document request form.

If a Purdue Libraries book that you need is currently checked out, you may place a recall on it using the "Recall this Item" link, or you may place an interlibrary loan request for it and we will borrow it from another library.

Turnaround Time

Turnaround time depends on many variables. Here is current turnaround time information for items requested through interlibrary loan. (Delivery of locally-owned items differ. See Document Delivery section for service and eligibility details.)

Quantity of Requests

A user may submit as many requests as necessary. However, large numbers of requests from a single user may not all be handled at the same time.

Exceptions: There are occasional exceptions to the method or place of delivery, such as cases in which the lending library has designated a piece as "library use only." ILL staff will alert users in these instances.

Due Dates for Book Loans

To avoid penalties, please return loans by the date indicated on the book band. Return ILL books to the drop box near the ILL Desk (HSSE Library, 2nd floor).

Renewals for Book Loans

Renewals are often possible. Please place your renewal request online at least 3 days before an item is due. Online renewals cannot be placed on or after the due date. If the item is overdue, you will need to contact the ILL office at 494-2803.

To request a renewal online, login to your Interlibrary Loan account.  Click the “Checked Out Items” link in the menu on the left side of the page.  Click the Transaction Number in front of the item you would like to renew.  If the item is renewable, a red “Renewal Request” link will appear above the item information.  Click the link to submit your renewal.

ILL staff will confirm the new due date by email usually a few days later when we have heard back from the lending library.


ILL staff notify users of overdue material. Failure to return ILL material on time, or to respond to a recall notice in a timely manner, may result in the loss of ILL and/or library privileges, and may also incur charges to cover the cost of the material plus overdue and/or processing fees.

Copyright Compliance

The Interlibrary Loan office complies with the U.S. copyright law and reserves the right to refuse a copying order if, in the staff's judgment, fulfillment of the order would involve violation of the copyright law.


The Libraries absorb the costs of most ILL transactions. In those rare cases when there would be a cost passed on to the requester, we will ask for your authorization in advance.

Nothing! The Libraries cover the cost of providing this service.

How do I place an order?

Do I need to check in advance to see if an item is available on campus or not?
No, just place your request. Libraries staff will handle your request as an on- or off-campus order as needed.

I'm on sabbatical away from the campus area. Will you mail a book to me?
Sorry, book delivery is only available to campus departments. Ask the university hosting your sabbatical work or a local public library about their interlibrary loan services. However, you can access electronic resources remotely (click here for details) or request electronic delivery of an article or chapter.

I'm a graduate research assistant or a graduate teaching assistant. Am I eligible for the service?
As a student employed at Purdue, your primary classification is as a student. We will scan and electronically deliver to students articles or chapters held in the Hicks Repository. If the item you need is held elsewhere in the Purdue Libraries, you will receive an email notice with the location and call number.
