New Ways to Research
We are pleased to announce a new online finding aid/catalog is now available for the John M. Longyear Research Library. Last year the MRHC received a Common Heritage grant from the National Endowment for the Humanities which allowed us to digitize family heirlooms, photographs, special papers and mementos. Thanks to this grant and a generous Longyear descendant, these digitized items and others from the collection will now be available to the public through the online catalog. This project is ongoing and more items will be added soon. Please use the button below to start your search.

It is a good idea to call first to speak with the librarian about your research project. Research materials can then be waiting for you when you are able to come in and view them. 906.226.3571

John M. Longyear, one of the first explorers to survey in the Upper Peninsula, made his home in Marquette in 1873. History was his passion and he amassed a large personal library of early maps, books and photographs of this region. In 1925, through a bequest of Helen Longyear Paul, daughter of J.M. Longyear, the Museum acquired his private collection. This became the nucleus of the J.M. Longyear Research Library.
