  • We try to fill requests as quickly as possible.  Due to COVID-19 measures, some lending libraries may have delayed response times.
  • If you opt out of communication, you will NOT receive notices when your items are available.
  • Rush?  Use "ASAP" in the Notes field.  Avoid the "Need By" date (request deleted after that date).
  • Delivery times vary.  Estimated turnaround times:
    • Articles & Book chapters: 3-5 days
    • Books: 7-14 days. Allow for shipping time. Use MERLIN and MOBIUS where possible.

Important Notes

  1. Interlibrary Loan items are borrowed according to the terms and conditions of the lending library (the library that loans UMSL the item).  There is no standard loan period.
  2. Limit requests to ten or fewer per week so we can process all requests in a timely manner.
  3. Renewals are solely at the discretion of the lending library.
  4. Replacement terms and costs for lost items vary according to the lending library and the item borrowed.
  5. ILL items are seldom recalled, but if they are, please return the item as soon as possible.
  6. Please return items on-time and in good condition. Late and lost items can jeopardize our ability to borrow from other libraries.
