Michigan Room

The Michigan Room is a local history collection housed on the lower level of the Library Headquarters in Port Huron. This collection, of particular interest to historians and genealogists, includes materials about St. Clair County and the Thumb Region such as plat atlases, out-of-print texts on Michigan history, directories, Civil War records, and High School Year Books. None of the Michigan Room materials may be checked out, and must be used in the library with the assistance of a Reference Librarian.

Please Note: Plat Atlases and City Directories are available in PDF format and are LARGE files. They may not load at slower connection speeds.

The freely available Adobe Acrobat Reader is required to view and print PDF files.

To ensure that you are not disappointed, please call ahead for your Michigan Room visit: (810) 987-7323 ext. 124 or 125
