A Systemic View of the UM System, MOBIUS, and WorldCat Catalogs.
The library catalogs at UMKC can viewed as a series of concentric rings, with each ring having access to more material.
Note that even within UM System Libraries, there are concentric rings. You can start with the UMKC Law Library, move out to UMKC as a whole, or all of the UM Libraries on all campuses in Missouri.
Beyond that is MOBIUS, which includes over 70 university libraries and some public libraries. It is important because it picks up St. Louis University and Washington University's law libraries (which are much bigger than UMKC's law library).
Lastly, there is WorldCat (also known as OCLC). WorldCat has a free version available at Worldcat.org, but we subscribe to a version on our databases page (https://umkclaw.link/db) that integrates with our inter-library loan request system. Scroll down to the bottom of the library's databases page to Worldcat FirstSearch and use your SSO to sign in. You should note that both MOBIUS and Merlin are cheaper for the library to use and that Worldcat doesn't not have as generous lending terms (i.e., shorter lending periods). There is no cost to you for using these systems.
Finally, if you have basic bibliographic information (title, author, year), you can use our inter-library loan form and get a librarian working on finding where the title exists in the system and retrieve it for you.
