What is ILL?

Interlibrary Loan (ILL) is an agreement among libraries to share library resources needed for research. WKU faculty, staff and students may use ILL as a supplement to the WKU Libraries.  Books, journal articles, dissertations, government documents, microfilm materials, and other items may be borrowed via ILL. 

How much does ILL cost?

All costs incurred for ILL requests are paid for from the WKU Libraries budget. There is no charge to our faculty, staff, and students.

How long does it take to get the material?

With electronic delivery, articles will take 1 or 2 days. If the lending library mails us the article, it will take longer. Typically, it takes 2-4 weeks to receive requested books (which are usually sent via US Mail); however, it may take longer depending upon workloads of WKU and lending libraries' ILL offices, completeness of the citation given, and availability of requested material. In order to have the request filled in time, it is important that you indicate a deadline date on the request form.

ILL may have difficulty obtaining recently published books from other libraries. It may be better for you to request that your library liaison purchase it for the WKU Libraries' collection.

Are there any restrictions?

Interlibrary Loan (ILL) policies restrict the following:

We regret that we cannot fill requests for textbooks currently being used at WKU or materials for course reserves.  Copyright law and international Interlibrary Loan codes may place restrictions on what materials may be borrowed.  Budgetary restraints dictate that we must limit ILL requests per patron to 5 per day with a maximum of 25 per week.

How do I request an ILL?

Before submitting a request:

Check One Search online catalog (formerly TOPCAT) and our  E-Journals to be certain we do not own the material you are requesting!
Here are some helpful hints:

    • Check the online catalog under both author and title
    • Check our  E-Journals holdings to make sure we don't have the article available online.
We may have the material, even if it is not on the online catalog! Some U.S. government documents are not in the catalog. Please reach out to one of the following resources:

Once you have verified the material is not available through one of the WKU databases, log into the WKU Interlibrary Loan system (formerly ILLiad) to submit a request:
