- Libraries & Spaces
We are currently installing new doors in the stairwell in Lauinger Library. During this time, visitors will not be able to use landings that are under construction, either to enter that floor or pass through en route to another. We encourage visitors to use the elevators, although the stairwell may still be used to access floors that are not under construction. Landings under construction should only be used in the case of an emergency.
Class of 1929, black and white photograph print (developed out process).
This documentary photograph from the University Archives was conserved in 2012. The photograph had a brittle support and had split in half, due to the emulsion fighting with the support over a long period of time. Heat and humidity had also caused chemical and mechanical decay. Conservation for this photograph included: surface cleaning; removal of tape from the back of the photograph; reattaching the separated halves; mending tears and filling in losses with Japanese paper and wheat starch paste; consolidating losses and lifted areas with gelatin solution; humidification of the print; and hinging the print into a window mat.
