The MHS is open! The library is open by appointment only. Exhibition galleries are open Monday through Friday, from 10 AM to 4 PM.
Please visit our exhibition page for more information. Learn more about our COVID-19 protocols to keep our visitors and staff safe. 

Visiting the Library

The MHS library operates differently from most public or university libraries. While we strive to provide researchers with access to all our collections, our primary concern must be to preserve our unique materials, and for that reason we enforce strict security protocols. The pages in this section—What to ExpectWhat to Bring, and How to Prepare--will help you become familiar with our policies and procedures.

Library Hours

The MHS library is open to the public for onsite research visits. To protect the health of researchers and staff amid the ongoing COVID-19 pandemic, the MHS  has implemented the following temporary policies:

  • The library is open Monday - Friday, 10AM to 4:45PM. 
  • Research is by appointment only. 
  • Appointment requests must be made by 2pm Thursday of the previous week.
  • Researchers must provide proof they have received an FDA approved COVID-19 vaccination prior to arriving at the MHS
  • A well-fitted mask covering the nose and mouth must be worn in all public spaces

Please visit our Appointment Request Form to select your preferred visit dates.   

The MHS Library is committed to providing all researchers with access to our collections and will continue to offer expanded reference and reproduction services. Researchers who are unable to visit the MHS at this time are encouraged to explore our virtual reference options and reproductions services for more information about the resources available to all researchers at this time.
