The Bentley Historical Library is now open by appointment only for U-M faculty, students, and staff.

Please use this link to request an appointment.

For all researchers, we are happy to schedule a video consultation before or instead of a visit to the library.

Please email us at bentley.ref@umich to set up a consultation.

The library’s Reference department will continue to receive and respond to remote requests from researchers who are not affiliated with the University, but our ability to check our physical collections remains limited and it may take us a while to respond.

To make a remote research request, please email

To keep our visitors and staff safe, and to comply with state law and university regulations, the Bentley has instituted the following procedures for using the reading room in person.
