Over fall break, scaffolding went up along the Wall Street side of Sterling Memorial Library as inspectors examined the north nave exterior wall for leakage problems.

University spokesman Tom Conroy said in an email that leaks had been occurring above several windows on that side. He added that the facilities staff is in the process of determining a permanent solution for the problem.

Leakage problems can dramatically shorten a book’s lifespan. In January 2006, steam from a leaking pipe had damaged a collection of books in Sterling’s lower level. While then-evening supervisor Matt Glickman described the books as “relatively low-value,” maintenance personnel were forced to close the downstairs staff section and a study area called “Machine City” for repairs.
