Visit the Library
Open to the public, the library welcomes all researchers who wish to use the collections, view exhibitions, and attend events.
The Library building is currently closed to all researchers, but we are open online. This is a continually evolving situation so please check back for updates.

Availability of Materials
No appointment is required to use the library, but because many of our collections are stored off-site and/or have access restrictions, you are advised to check the availability of materials in advance of your visit.
We strongly encourage you to search HOLLIS Catalog to get more information about the items you think you will want to use. The catalog records will indicate whether items are stored off-site, restricted, or closed. If the item(s) in which you are interested are stored off-site and/or restricted, or if you are having difficulty searching the library holdings, please contact us for further assistance.
When You Arrive
All reading room users are required to register upon their first visit and to show one form of photo identification. Reception staff will assign a locker for any bags, cases, or valuables that you bring into the library. Once you have registered, proceed to the second-floor reference desk, where staff will assist you with filling out call slips and finding the materials you need.
Please read our Library Policies prior to your visit.
All materials are retrieved by staff after a call slip has been submitted. With the exception of reference books, all library materials must be used in the Carol K. Pforzheimer Reading Room.
You are encouraged to bring a digital camera or camera enabled device. Digital photography is allowed for research purposes. Please read our Reading Room Digital Imaging Policy.
The Library also offers scanning services.
Laptop and tablet computers are welcome in the reading room. Electrical outlets and network connections are available at each seat. A wireless network is also available.
