The MHS Library
Open to All
The library is free and open to the public, welcoming researchers of all ages and experience levels. The library does not lend materials, but anyone wishing to view the collections can register as a researcher through our Portal1791 online request system and use materials in the library. In many cases, we can reproduce selected materials and send them to researchers who cannot visit the library in person.
Use the Library
Our library consists of an orientation room, a reading room, a reference area, and several microfilm reading stations. The library staff assists researchers with navigating our catalogs and collection guides, developing research strategies, and locating other libraries that may hold materials of interest. Our goal is to help researchers find the resources they need to complete their projects.
The “Visiting the Library” section of our website outlines library policies, procedures, and research practices. We strongly encourage researchers to review this information and to register for a Portal1791 account before visiting the library.
Please contact the Reader Services staff ( or by email) with any questions about preparing to use the library. Or, go to the "Virtual Reference and Chat Services" page to start a live chat with library staff.
