The day of your visit:

The Historical Collection is located on the third floor of the Welch Medical Library at 1900 East Monument Street, Baltimore, MD 21205. When you arrive for your visit please call 410-955-4797 and we will escort you up to the reading room.

Researchers may bring only silenced cell phones, digital cameras, wallets, pencils, and laptops or tablets without cases into the reading room. Power cords and headphones for electronic equipment are permitted, as are rulers and magnifying glasses. All other materials will be stored for you.

Please wash your hands before entering the Rare Book Room. If you have used hand sanitizer, please thoroughly dry your hands so damaging residue is not transferred to the materials. Researchers will not wear gloves, unless handling artifacts.

While in the reading room, you will have access to one box or up to 3 volumes on your table at one time. Let staff know when you are finished, and they will remove the box/book(s) and set up any additional material you have requested.
