Interlibrary Loan and Document Delivery (IDD): COVID-19 and IDD

A Guide to all IDD Services

Update on IDD Services and Operations

USC Libraries Interlibrary Loan and Document Delivery Department (IDD) and Course Reserves service is currently experiencing operational delays but as the situation improves and restrictions are alleviated, we should return to normal operations. In the meantime, please note the following:

• Home delivery of physical materials may take up to 3-4 additional days. 

• Patrons working with our electronic course reserves system may experience a small delay depending on the materials being requested.

Please note: If you requested materials that can alternatively be purchased in electronic format (e.g., as e-books or streaming videos) you may receive notification the materials are available.

IDD Service Changes During USC Libraries' Closure

IDD Spring 2021 Operations Resume

On behalf of the USC Libraries and IDD team, we would like to thank all students, staff, and faculty for their support and understanding during these recent months. We are definitely keeping busy with all of the requests that you have been submitting!  Also, we would like to thank you for your patience with any request delivery delays as we are doing our best to process requests as quickly as possible with the limited staff that we have onsite.

IDD services including Scan & Deliver and Home Delivery have resumed with onsite scanning and partner institutions fulfilling requests for book chapters, articles, and conference proceedings. Please keep in mind that many of our interlibrary loan partners have yet to reopen fully, but we will do our best to fulfill requests.  

If you submit a request for a physical item that cannot be fulfilled with an eBook, we will process your request via Home Delivery if available from USC's collection.  Please note that both UPS and the US Postal Service is experiencing unprecedented volumes and limited employee availability due to the impact of COVID-19.  We appreciate your patience!

IDD services have changed since USC enacted precautions against the spread of COVID-19.  Please note that the current situation remains fluid and is subject to change. Check this page as well as the Current USC Libraries' COVID-19 page for continual updates. 

ILL Physical Borrowing 

  • IDD has restarted physical borrowing from other libraries for physical items not available or owned by USC Libraries.  Please note that not all libraries across the country are lending physical items, however we will do our best to obtain the item needed.
  • At this time, borrowed physical items will be delivered as any Home Delivery request.  So please be sure your home address is updated in your IDD account.  
  • Please note that borrowed physical items will have shorter circulation periods than normal USC items.  Most items are renewable, however.  
  • In order to facilitate expedited delivery, IDD will still pursue an e-book option for access if available. 

ILL Book Returns

  • Interlibrary loan books can be returned in one of the library drop-off boxes on campus.  There are two located in McCarthy Quad between Doheny Memorial Library and Leavey Library and one behind Leavey Library.  This is an exception to our current rule that ILLs must only be dropped off at the Leavey circulation desk.
  • If coming to campus, please be sure to view Trojan Community Guidelines for news about Campus Access.
  • If you need to return your ILL books and are unable to come onto campus, we do have a dropbox at the USC Hotel on Figueroa.  You can also e-mail us at with the title(s) and transaction number(s) (TN).   We can supply a UPS return label that must be printed out and attached to your return.  Please review our Home Delivery policies for details.
  • Please note that for return shipping, we can only issue a UPS return label.  We are unable to supply US Mail postage or provide refunds if you have already paid to return items.
  • You may also request a renewal if you need your ILL items longer, however these are subject to approval of the owning library if the item was borrowed from another institution.  For details, please see ILL Renewal


Home Delivery

  • All USC faculty, staff, and students can request to have physical materials mailed to their home addresses.  
  • Please submit your request through the Interlibrary Loan and Document Delivery website.  
  • Items are shipped UPS Ground.  Be sure that your current address is up to date on your ILL account. In the Interlibrary Loan and Document Delivery website, check the My Account section to view or change your mailing address.
  • Please note that we can only deliver to U.S. street addresses at this time.  We are unable to ship to P.O. boxes.
  • For more information, please see Home Delivery for policies and procedures.
  • ​Campus Delivery to faculty offices is temporarily suspended.


Scan & Deliver

  • Book chapter and article requests will continue to be filled from USC print resources if available as some libraries will be closed and collections inaccessible.
  • Book chapter and article requests from materials not owned by USC or unavailable will be processed, however please note that most libraries nationwide are only supplying from electronic resources at this time.

We appreciate your patience as we have limited staffing but as always we will do our best to support your learning and research needs.
