Attention MOBIUS Borrowers: Changes to MOBIUS During April and May

MOBIUS will transition to a new library catalog and resource sharing system in April and May of this year. The migration will begin on April 18th with a 5-week freeze on requesting materials from MOBIUS libraries. To facilitate a smooth transition to the new system, due dates for all MOBIUS materials will be adjusted to May 17th.

MOBIUS Timeline

  • April 17: The last day to request items through MOBIUS
  • April 18: Freeze on requesting from MOBIUS
  • May 17: All MOBIUS item are due
  • May 22: Estimated date that MOBIUS will resume borrowing and lending

Please do not hesitate to reach out to us at if you have questions. We will explore options to ensure you have the materials you need during this transition, or you may request items directly through ILL@MU now.

Checkout practices will remain normal for all MU Libraries, UM system libraries (UMKC, UMSL and Missouri S&T) and University of Missouri Libraries Depositories (UMLD) borrowing; no disruption will occur between MU/UM/UMLD libraries during the MOBIUS transition.

We appreciate your understanding and look forward to resuming MOBIUS borrowing and lending at the end of May. Thank you for your cooperation.
