UMSL Information

New catalog launch

The University of Missouri Libraries are pleased to announce our new catalog interface will go live on June 22, 2022. The new system will allow patrons to search books, journals, online resources, and more in one platform. All items already checked out to patrons will migrate to the new system.  

We will be transitioning to our new system from June 18-21, 2022. During this transition materials will be processed manually which may result in delays in updating your account for items being checked out and returned. We will make the necessary adjustments to dates to avoid fines or other fees.  

Requests for materials not owned by the University of Missouri Libraries can continue to be submitted via Interlibrary Loan or MOBIUS.  

If you have any questions or concerns, please contact your library’s circulation desk.  

Catalog changes coming soon

The University of Missouri Libraries and the State Historical Society of Missouri are delighted to announce that our new catalog will be launching this summer. Our new system will allow users to search books, journals, media, and more across our collections.

The University of Missouri Libraries and the State Historical Society of Missouri will implement the system at the same time. Our launch date will be announced as soon as it is finalized.

Continuance of MOBIUS Services

MOBIUS will not shut off on April 15, 2022, as previously announced. UM System users will be able to keep privileges at all MOBIUS libraries. When we launch our new catalog, there will be a link to the MOBIUS catalog in each UM System Library Catalog.

Disruption of MOBIUS Services

Due to upcoming software changes to the UM System Libraries catalog, all campuses will need to temporarily suspend the borrowing and lending of materials through MOBIUS beginning April 15, 2022 and shift to other methods of obtaining materials for users. MOBIUS is our statewide consortium of academic and public libraries that agree to share materials. The UM System Libraries have every intention of reinstating MOBIUS services as soon as our new software allows. However, we will be without MOBIUS services for at least one year. This disruption does not impact MERLIN items, as those are items shared within our four campus system. Users can still receive materials from other libraries using the Interlibrary Loan process.

We are working with our vendors and MOBIUS to reinstate services as soon as possible. We will alert users as soon as we know more about reinstating MOBIUS across the four campuses. The UM System Libraries apologize for any inconvenience this causes to our users.

Users should:
• Return all MOBIUS items to the library by their due date.
• Check to find out your due dates for MOBIUS materials.
• Review materials checked out from the library and look for items with the green or blue MOBIUS band around the cover.
• Work with library staff to obtain currently checked out MOBIUS items from Interlibrary Loan, if the materials are still needed for research.
