We share resources with thousands of libraries. Use this account to request books, articles, or other materials that we don't own. Or if you're a DL student, we will also send library-owned materials to you.

Current authenticated NPS users can request to borrow materials from other libraries in support of learning, teaching, research, and other NPS mission-related efforts.

View ILL Renewal tutorial (3 min.)


  • Login to your Interlibrary Loan account 
  • Under View, click "Checked Out Items"
  • Click the appropriate transaction number
  • Click "Renew Request" located at the top of the page (see note below)

The “Renew Request” link only appears for renewable items.  If you do not see this link, it may be for one of the following reasons:

  • The lender does not allow renewals – please return item by due date
  • A renewal has already been granted and no further renewals are allowed – please return item by due date
  • The item has been recalled by the lender and must be returned immediately

When only the “Clone Request” link appears, you may click that link to request another copy of the item – another copy will be requested once the original loan has been returned.

You may also contact us for assistance at least 3 business days prior to the due date.

Please also note:

  • If you have overdue items, you may be blocked from borrowing other materials until the items are renewed or returned.
  • Your ILL privileges may be suspended, and no further materials may be checked out until the overdue ILL item has been returned.
  • It is your responsibility to replace lost or damaged items.
Please check with the Information Desk, before ordering replacement items.
  • Replacement of items will be considered on a case by case basis with exact replacement of items as the first course of action.
  • Many lending libraries charge a minimum of $100 per item for lost or damaged materials plus processing fees.
  • Textbooks. Students are expected to acquire copies of their required textbooks on your own. Every quarter the library places a number of required course texts on reserve at the library. Please check with us or with your professor to see if a text will be placed on reserve.

  • Books published in the current year. You may use the Book Purchase Form.

  • Audiovisual and microformat materials
