To find BOOKS, you have several options beyond the "Books & Media" tab found on the MU Libraries homepage:
MERLIN : Use the MERLIN Catalog to find books at MU and the other campuses of the University of Missouri. If we don't have the book here at MU or if our copy is checked out, you can request it from another UM library by searching ALL MERLIN.
MOBIUS: If the book you need is not available through MERLIN, you can request it from MOBIUS, a statewide network of Missouri college and university libraries.
ILL (Interlibrary Loan): If the book you need is not available through MERLIN or MOBIUS, you can request it via Interlibrary Loan or WorldCAT, an international catalog containing over 95 million records of books and other materials held in libraries worldwide.
