The library is an essential study and resource location for UCD students, as well as for many UC Davis alumni.
The main entrance used to face north towards the Quad (the large rectangular grassy field which was the historic geographic center of campus).
When UC Davis shut down during World War II, the main reading room was used to train the Army Signal Corps.
Expansion of the library (stage two) began about 15 years later in the 1960s, which added the south and east sides of the building.
The last expansion stage, which opened spring quarter of 1990,[2] added the western side of the library and once again moved the main entrance to the west.
