Knight Library is the main facility of the University of Oregon's (UO) library system. It is located on the university's campus in Eugene, Oregon, United States. The library design is emblematic of the architecture of the university's older buildings, and it serves as a hub of student activity. As of 2008 it has a collection of more than 3 million volumes.
Three major renovations of the library, in 1950, 1966, and 1994, have kept the building up-to-date and it is a daily hub of learning and research to University Of Oregon's more than 20,000 students. 1994's $27 million renovation added 132,000 square feet (12,000 m²) to the building. The project was partially funded by Phil Knight, UO alumnus and cofounder of athletic shoe company Nike. The library was renamed Knight Library in honor of Knight's family.
The original 1937 section of the library, designed by Lawrence, contains inscriptions along the tops of each of seven large windows on the main (north) facade. These read, "Philosophia," "Historia," "Religio," "Ars," "Natura," "Societas," and "Litterae," and are meant to represent (in Latin), the seven major disciplines contained in the library's collection.
