Closed Collections

Renovation activities may result in the unavailability of some collections. The following list of closures will be updated regularly and is subject to change. In addition to materials on this list, individual items may be already in use and therefore unavailable at the time they are requested for research. These uses may include classes, conservation, and use by other researchers in the reading room. Additional time may be required to provide access to some items. If you have questions, please contact Houghton Public Services staff.
