Note: E-books cannot be requested.
If WUSTL has the paper book, consider requesting it (approx. 4 business days to arrive at your pick-up location). The system will email you Ready for pick-up.  Monitor the status through My Catalog.

If WUSTL does not have the book, consider requesting it through the MOBIUS system (approx. 4-7 business days to arrive at your pick-up location).  The system will email you Ready for pick-up.  Monitor the status through My Catalog.
If the book is available in the MOBIUS system, and you don't want to wait for it, you can visit the MOBIUS library and check out the book. Bring your Washington University ID card.  NOTE: You cannot visit St. Louis County Library with your WUSTL ID.  St. Louis County Library does not participate in the on-site MOBIUS visitor check-out program.
Return the MOBIUS book to any Danforth/West Campus library.

If neither WUSTL nor MOBIUS has the book, consider requesting it through the ILLiad Interlibrary Loan System (approx. 2-3 weeks to arrive at your pick-up location).  The system will email you Ready for pick-up.  Monitor the status through your ILLiad account.
Return ILLiad items to the Brown School Library or to Olin Library.
