Willamette's library was designated as a Federal Depository Library in 1969. It serves as the library for the 5th Congressional District population. The library selects around 20% of the documents available with areas of concentration in earth sciences, education, history, politics, economics, health, accounting, business, government, public policy, human resources, and others. Additionally, the university selects major items from the Census Bureau, Bureau of Labor Statistics, the office of the President, and Congress. Other materials come from the Smithsonian Institution, the Small Business Administration, the Department of State, and the Department of Education to list a few.
