Interlibrary Loan Services

Interlibrary Loan (ILL) is a service that allows you to request materials we don’t have at the University Libraries. Penn State faculty, staff, and currently enrolled students are eligible to use the service. You’ll need a Penn State Account and ILL (ILLiad) account to use the service.

How it Works

We recommend that you begin by searching the Libraries Catalog for the materials you need. Our databases and library catalog contain links to e-resources as well as links to request unavailable materials through the Interlibrary Loan service. We also recommend using WorldCat (OCLC FirstSearch) where you can search for and request the holdings of libraries worldwide. Use the "Request Item via Interlibrary Loan" link in the WorldCat record to populate an ILLiad request form. If you know the item you are interested in requesting, you can also fill out a request form manually in your ILLiad account.

Once you’ve submitted your request, our automated system and experienced staff determine the most efficient way to get the item for you, looking at various request networks that are available to us, such as E-ZBorrow (PALCI), UBorrow (Big Ten), and more.

The copyright law of the United States (Title 17, United States Code) governs the making of photocopies or other reproductions of copyrighted material.

Under certain conditions specified in the law, libraries and archives are authorized to furnish a photocopy or other reproduction. One of these specific conditions is that the photocopy or reproduction is not to be "used for any purpose other than private study, scholarship, or research." If a user makes a request for, or later uses, a photocopy or reproduction for purposes in excess of "fair use," that user may be liable for copyright infringement.

This institution reserves the right to refuse to accept a copying order if, in its judgment, fulfillment of the order would involve violation of copyright law.
