MOBIUS is a consortium of libraries in Missouri that allows current students, faculty, and staff at member libraries to directly request materials from other libraries.
Interlibrary Loan (ILL) is a service the Law Library provides to Law Students, Law Staff and Law Faculty in which we negotiate borrowing and lending to and from thousands of other libraries

Who may use the Law Library’s Interlibrary Loan (ILL) Service?

Only Law School faculty, staff, and currently enrolled students may use the law library’s ILL service*. Other Washington University faculty, staff and students must use Olin Library’s Interlibrary Loan Department. Everyone else must use their local public library’s ILL service.

*MOBIUS & ILL physical book services require on campus pickup and return.
