The MCommunity Directory is
A public directory of people and groups at the University of Michigan. All current members of the U-M community have profiles in the MCommunity Directory. This includes faculty, staff, students, retirees, alumni, and sponsored affiliates. Anyone who has a profile in the directory can create groups in the directory.
An enterprise directory—that is, it covers the entire university. It is part of a larger identity management system that allows the university to know who is and is not a member of the U-M community so that central offices—as well as departments, schools, colleges, and campuses—can grant and remove access to their online resources as needed and appropriate.
To learn about using the directory, managing your own profile and groups, and more, see MCommunity Directory Documentation.
Note: Students can check the Office of the Registrar's U-M Student Rights and Student Records page to learn what information about them is considered "directory information."
