What to Expect
The MHS library is free and open to the public. All visitors wishing to use the library must create a user account in Portal1791; present a valid, government-issued photographic ID upon arrival; and be photographed by MHS staff.
At each visit all researchers report to the orientation room to check-in and receive an ID badge and lanyard, which must be worn by the researcher at all times while in the library.
Personal belongings are not allowed into the library. Researchers secure personal belongings in the lockers provided. Laptop computers and cameras are the only personal items allowed into the library. These items will be checked by a member of the library staff upon exiting the reading room. For more on this policy see "What to Bring."
All library and exhibition areas are monitored by a recording CCTV system.
Before entering the library, all first-time researchers must create a personal account in Portal1791, the Society's automated request system. We recommend this be done in advance of your visit, but it can also be done at the MHS. Upon arrival at the MHS, researchers complete the registration process by presenting a valid-government issued photo ID and being photographed by MHS staff.
After registering and securing personal belongings, all first-time researchers meet one-on-one with a member of the Reader Services staff to receive a library orientation.
The MHS is a closed-stack, non-circulating library. Researchers place requests for materials using their Portal1791 account. Requests can be made directly from the online catalog, ABIGAIL, or from online collection guides. The Reader Services staff retrieves materials throughout the day up until 45 minutes before the library closes.
Approximately one-third of the MHS collections are located at an offsite storage facility. Requests for offsite materials should be place via Portal1791 at least two business days is required for use of these materials. Materials stored offsite cannot be delivered to the MHS on Saturdays. Requests for materials to be used on Saturdays must be placed by the previous Wednesday. The Society is limited in the amount of material that can be delivered in one day. Researchers needing more than six items from offsite storage should provide additional advance notice.
All offsite materials are identified in ABIGAIL and the Collection Guides with the call number "OFFSITE STORAGE." If you have questions about requesting materials from offsite storage, please contact the reference desk at 617-646-0532 or email@example.com.
Microforms & Surrogate Copies
To ensure long-term preservation of manuscript materials the MHS provides microfilm or digital editions of many of our collections. The MHS also holds the microfiche edition of both the Evan and Shaw-Shoemaker Series of Early American Imprints. Whenever they exisit, reseachers should request the surrogate copy within Portal1791.
The MHS has ScanPro 2000 workstations for researchers working with microforms. The ScanPro allows researchers to create multi-page PDF files that can be emailed or saved to their own USB drive.
A limited number of MHS microfilm collections are available for interlibrary loan and/or purchase. For more information about obtaining microfilm for ILL/purchase please vist the Microforms page.
For security purposes, all researchers must work at individual work tables in the reading room and must submit individual call slips when making requests for materials. At the discretion of the reference librarian, special arrangements can be made to accommodate research teams that must work together to complete a specific project. If you would like to schedule an appointment please review our group research policy and contact the reference librarian at 617-646-0561 to confirm staff availability. Please note that a $45.00 per hour set-up and supervisory fee may apply.
