Frequently Asked Questions

OHS’s research library welcomes walk-in researchers and does not require advanced appointments to use the library. Due to space limitations in OHS’s downtown location, most of our library materials are stored off-site and may require up to one week’s notice to retrieve. If you are looking for specific materials or are on a tight research timeline, we recommend contacting reference library staff before visiting by emailing To make the most of your time in the reading room, librarians are available to provide consultations by email and identify relevant collections in advance.

OHS reference library staff will ask researchers to register and store any non-research related items in a private locker. The library’s collections are held in closed stacks and are not open to browsing by visitors. Reference staff can help identify and retrieve collections during visits.

Conducting archival research takes time. Researchers should expect to spend a few hours in the reading room during their visit, depending on the complexity of their research.

Returning researchers should be aware that OHS has reconfigured collections storage to better accommodate current research needs. Some materials that were previously available in our downtown facility are now stored off-site and must be requested at least one week in advance of your visit. This includes serials and government documents, architectural drawings, many microfilmed materials, and selected titles from the book collection.

Researchers may bring their own materials to the library, with a few exceptions. Pens and highlighters are not allowed in the reading room. Please be prepared to use paper and pencil or a laptop or mobile device to take notes. Researchers are allowed to bring their own accessibility tools, such as magnifiers, as long as these tools do not come in direct contact with collections materials. Please check with reference staff before bringing any personal research materials or books into the reading room.

Cell phones must be kept on silent; researchers are asked to exit the library to take phone calls. Food and drink are not allowed in the research library. A drinking fountain is available for public use during visits.

OHS’s research library welcomes visitors of all ages; children under 15 must be accompanied by an adult. Accompanying adults are responsible for minimizing disruption for other researchers and ensuring the safe handling of library materials at all times. Many researchers find that bringing activities for younger children helps occupy their time.

Storage space is limited downtown; only a portion of the library’s collections can be stored on-site. Research library materials are stored based on patterns of use, size of collection, and storage configuration.

Please note that some changes to storage locations were made as part of the library’s reopening in 2021. Materials stored off-site are indicated in the library catalog by the location code GSF. Please check with reference staff at least one week prior to your visit to ensure that the materials you need are available on-site.

OHS allows non-flash photography of library collections materials for personal research use only. To minimize disruption to other researchers and prevent damage to collections materials, please do not bring additional equipment, including scanners, tripods, and lights. We ask that researchers not stand on chairs, place materials on the floor, press book spines, or engage in other activities that compromise the integrity of fragile collections materials.
