We cannot guarantee the arrival date of any ILL material so please plan well in advance.
Tip: If you need a book/book chapter/article over the weekend when all ILL offices are closed, then perform a "WRLC (Georgetown U. + Consortium)" Advanced Search to determine which, if any, local academic library may own a copy. Verify that in the matching catalog results that a book has an 'available' status or that the coverage of the print/electronic journal matches your citation. Then visit the owning library to check-out/scan/download the material on site. (Note: You cannot check-out books directly at any of the local law libraries).
