The library is located on the University of Michigan’s North Campus, and offers free parking on the south side of the building for those who want to research in person. For tips on how to best find what you need while you’re here, please visit the Researching in Person page.

The Detroit Observatory is also part of the Bentley Historical Library. Constructed in 1854, the observatory was the first research facility built at the University of Michigan. Completely restored with original instruments, it is open for tours on select Sundays, and for viewing nights throughout the year. Please visit the Detroit Observatory page for more information.
