We describe MOBIUS as "easy and fast" because if you see a regular book that you want at another library, you can have it sent to the University of Missouri-St. Louis quickly, in as little as 3-5 full working days. And the process is a simple one as you will find out presently. There are two ways you can gain access to MOBIUS. One way, as you've seen, is through the button on the library's catalog. And the other way is directly from the UMSL Libraries' homepage.
